GN change disallows sources that aren't a source, header, or object file.
We need to pass `process_only` flag to process_version to not create source_set
out of the version file.

Disallow non-buildable sources in binary targets

When adding a file that's not a source, header, or object file to a source_set,
loadable_module, shared_library, executable, or static_library, gn will now
generate an error like the following:

ERROR at //third_party/protobuf/proto_library.gni:369:15: Only source, header,
and object files belong in the sources of a
source_set. //out/Test/pyproto/google_apis/gcm/protocol/mcs_pb2.py is not one of

    Store |initiator_origin| in FrameNavigationEntry.

    Changes in this CL
    ==================

    This CL:

    1. Updates FrameNavigationEntry::UpdateEntry and
       FrameNavigationEntry's constructor so that they both take
       |const base::Optional<url::Origin>& initiator_origin| which
       gets stored in a new FrameNavigationEntry::initiator_origin_ field.

    2. Updates callers of FNE::UpdateEntry and FNE's constructor to
       provide/propagate the initiator as needed.  This includes
       adding an |initiator_origin| parameter to
       - NavigationEntryImpl's constructor
       - NavigationEntryImpl::AddOrUpdateFrameEntry
       - NavigationController::CreateNavigationEntry
       (the list above is not necessarily exhaustive/complete)

    3. Uses the new |FrameNavigationEntry::initiator_origin()| from
       NavigationEntryImpl::ConstructCommonNavigationParams (which
       used to always provide |base::nullopt| initiator for history
       navigations - always treating them as browser-initiated, rather
       than replaying the original initiator).

    The changes above makes sure that the right Sec-Fetch-Site http request header is
    "replayed" during history navigations.  The CL adds browser tests and
    WPT tests to cover the new, desired behavior.

    Follow-up changes
    =================

    This CL does not:

    - Use |FrameNavigationEntry::initiator_origin()| in GetOriginForURLLoaderFactory
      in render_frame_host_impl.cc (this will be done in a follow-up CL at
      https://crrev.com/c/1672176)

    - Handle persisting |FrameNavigationEntry::initiator_origin()| for
      session restore (this is tracked in a separate https://crbug.com/976055).

    This CL moves the files that are currently in the
    //components/signin/core/browser:shared GN target into the structure
    described in this document:

    https://docs.google.com/document/d/1p_kahITGFgv7PehQ61-thRVR3Hrdaf3tLryMytTRPYs/edit#

    Namely, files intended for usage by the entire signin component and its
    consumers are moved into a new //signin/public/base/ directory. Files
    that are conceptually part of the IdentityManager public interface are
    moved into //signin/public/identity_manager/.

    This change was done in two parts:

    1. A script that did the code moves and corresponding renames,
       include path changes, etc.
    2. Manual followup that changed GN files and DEPS to reflect the new
       structure.

    For ease of reviewing, I uploaded 1 as the original PS and 2 as PS2.

    windows spellchecker integration.

    This CL aims to implement windows spellchecker integration in Chromium
    project, so that user can switch to use windows spellchecker or
    hunspell spellchecker at run time. We need to implement platform
    agnostic interfaces to integrate windows spellchecker into Chromium. We
    also need to refactor some code to enable runtime switch between
    Windows spellchecker and hunspell spellchecker.

    We have outlines following steps to achieve the goal:

    (1) Implement spellcheck_platform interface.
          spellcheck_platform is an interface that platform-specific
          spellchecker needs to implement. Create spellcheck_platform_win.cc
          which contains Windows specific logic. All COM calls are happeninn
          on the background thread. spellcheck_platform API are all async.

    (2) Refactor SpellCheckHostChromeImpl.
          SpellCheckHostChromeImpl is a derived class from SpellCheckHost
          which provides basic spellcheck support. Mac has separate
          implementation located at spell_check_host_chrome_impl_mac.cc.
          Windows can share the same implementation, therefore, I move the
          code to the base derived class at spellcheck_host_chrome_impl.cc
          and delete mac specific file.

    (3) Refactor SpellingRequest.
          SpellingRequest is owned by SpellCheckHostChromeImpl and is
          currently located at spell_check_host_chrome_impl_mac.cc file.
          Created seperate files spelling_request.h and spelling_request.cc
          for defination and declaration of SpellingRequest.

    (4) Refactor CreateNativeSpellingEngine().
          CreateNativeSpellingEngine() used to live in seperate files for
          different spellcheckers. For platform specific spellchecker, it
          is located at platform_spelling_engine.cc. For hunspell
          spellchecker, it is located at hunspell_engine.cc. In order to
          enable runtime switch between those two spellcheck services, We
          need to have a uniformed definiation. Therefore, I create a new
          fine spelling_engine.cc base class and put a uniformed defination
          of CreateNativeSpellingEngine().

    (5) Define USE_RENDERER_SPELLCHECKER build flag
          We already have USE_BROWSER_SPELLCHECKER build flag. The decision
          to use platform specific spellcheck or hunspell spellcheck is
          made at build time. It's not the case anymore. We want to switch
          between spellcheck services at runtime. use browser spellcheck
          (platform specific spellcheck) and use renderer spellcheck
          (hunspll spellcheck) are no longer mutually exclusive. I created
          USE_RENDERER_SPELLCHECKER build flag to indicate usage of
          hunspell spellcheck service.

    (6) create feature flag kWinUseBrowserSpellChecker.
          In order to enable runtime switch between two spellcheck services.
          We need to have a feature flag to indicate which spellcheck
          services to use. I created kWinUseBrowserSpellChecker. The flag
          only has effect on Windows.

    (7) Create spellcheck::UseBrowserSpellChecker()
          In order to enable runtime switch between platform specific
          spellcheck and hunspell spellcheck, we need a runtime check
          instead of build time check. I created a runtime check an put it
          in file spellcheck_features.cc. For Windows, the method will check
          for feature flag kWinUseBrowserSpellChecker to determine which
          spellcheck service to use. On all other platforms, it will return
          build time flag.

    After these steps, we enabled Windows Spellcheck Services integration
    and also achieved runtime switch between platform spellchecker and
    hunspell spellchecker for windows platform.

    ProfileManager::RegisterTestingProfile() now takes a std::unique_ptr

    This commit clarifies previously established ownership semantics of
    Profiles within ProfileManager through the use of unique pointers.
    Changes were made to the parameters of
    ProfileManager::RegisterTestingProfile() and
    ProfileManager::RegisterProfile() to take a std::unique_ptr instead of a
    raw pointer. A further change was made to the return type of
    ProfileManager::CreateProfileAsyncHelper() from a raw pointer to a
    unique pointer. All callers to the aforementioned functions (including
    unit tests) that made calls to the two functions are updated to pass in
    unique pointers.

    WebUI: Move md_select_css.html from html/ to cr_elements/

    This is done for two reasons.
    1) Consistency: md_select_css.html and action_link_css.html are the only
       <dom-module>s that don't reside under cr_elements/ or
       cr_components/. Other shared styles (like hidden_style_css.html) are
       already under cr_elements/.
    2) For the purposes of auto-generating Polymer3 files, moving those files
       over eliminates a corner case (with regards to path rewriting) that
       otherwise needs to be handled by polymer_modulizer().

    Also note that |flattenhtml| was unnecessarily used for md_select_css.html,
    removed as part of the move.

    action_link_css.html will be moved in a separate CL.

    [Sync] Remove encryptor_ member from Cryptographer

    The only reason to have Encryptor dependency inside Cryptographer is
    methods related to so-called bootstrap token. They provide logic
    related to persistence of custom passphrase keys and strictly don't
    seem to belong Cryptographer level. While we can't factor them out
    right now, because it would mean intrusive and big changes in Directory
    codepath, we reduce this dependency by replacing |encryptor_| member in
    Cryptographer class with |encryptor| parameter in corresponding methods
    family. It allows to simplify significant amount of code, related to
    plumbing Encryptor, while it's actually not needed.

    This allows us to use this mechanism in CSS:

      @media (prefers-color-scheme: dark) {

    to vary styles for Chrome web UI in dark mode while also disabling via
    feature on certain platforms.

    This unblocks us from migrating to the @media query (from the existing
    [dark] attribute syntax) and later removing a bit of JS/C++ custom code
    in favor of simply using the web platform.

    SyncPrefs: Change default value of "IsSyncRequested" to false

    This is achieved by migrating the "SyncSuppressed" pref to a new
    "SyncRequested" pref.

    Before this CL, there was a pref called "sync.suppress_start", which was the
    inverse of the "IsSyncRequested" flag in SyncPrefs/SyncUserSettings. It was
    false by default, meaning Sync was considered "requested" even if the user
    had never even attempted to turn on Sync.

    This CL migrates the value over to a new "sync.requested" pref, which is the
    inverse of the old pref, and has the correct default value (not requested).

    If the old pref has an explicit value, then the migration is simply
    "sync.requested := !sync.suppress_start". If the old pref does not have a
    value, then there's generally nothing to migrate (and thus the implicit value
    of "IsSyncRequested" will change to false, which is the sane default state).
    However, as one special case of the migration, if the old pref is not
    explicitly set, but "IsFirstSetupComplete" is true, then that means Sync was
    actually enabled, but (probably through some past bug in the Sync setup flow)
    "SetSyncRequested(true)" was just never called. To correctly migrate users
    in this state, we set the new "sync.requested" pref to true.

    Apart from the migration edge case mentioned above, the different default
    value does not introduce a behavior change: All sync setup flows must anyway
    call SetSyncRequested(true) since they can't be sure what the previous value
    was.

We populate this field from `network::ResourceRequest`s

    Split cache: Network Isolation key for navigation resources

    Adds network isolation key in the ResourceRequest for navigations to be
    propagated to net::URLRequest. The key is also updated for redirects.

    Updates NavigationRequestInfo to have a network isolation key as a
    member instead of top frame origin. Also updated the corresponding
    intercepting browser tests in navigation_browsertest.

    Added browser tests to verify if the navigation resources (both main
    frame and sub frame) are expected to be cached including the redirect use
    case.

    Also removing the code in url_request_http_job.cc that was using top frame
    origin to create NIK if it was not already populated. This is because with
    this change we would have NIK being created in browser process for subresources,
    navigation resources and dedicated worker resources which were earlier using the
    top frame origin.

    (Note that sub-resources URL requests do not use this path and have their
    network isolation key filled up in the URLLoaderFactory).

    Prepare browser tests for NoRendererCrashesAssertion.

    This CL adds ScopedAllowRendererCrashes to browser tests that
    (expectedly or unexpectedly) might trigger a renderer crash.

    Right now a browser test might pass, even if a renderer process crashed
    during the test execution.  After https://crrev.com/c/1650463 a renderer
    crash will trigger an explicit test failure, but before this enforcement
    can start, existing tests that experience renderer crashes (expectedly
    or unexpectedly) need to declare this via ScopedAllowRendererCrashes.

    This CL was uploaded by git cl split.

    Bug: 972220

Theme switching broke due to the introduction of "preferred color
scheme" into native theme. See Chromium change below.

On top of SetDarkMode that we already were doing, added
SetPreferredColorScheme that sets preferred color scheme to our
selection.

Also, had to patch ChromeContentBrowserClient to catch switching
preferred color in web prefs when the system color is switched. That
gets triggered by the system color change, for example via control panel
on Windows. The Windows specific implementation watches a registry value
and updates preferred color scheme in the native theme. Would be great
to intercept it there, but in that layer we don't have access to our
setting stored in profile prefs, from what I can tell. Hence, the patch
to ChromeContentBrowserClient where the setting is used. Ugly.

    Set preferred color scheme for high contrast

    This change adds logic to update the preferred color scheme based on
    the OS high contrast theme. If high contrast is not enabled, preferred
    color scheme will continue to be based on the OS dark mode state.

    A PreferredColorScheme enum was added to NativeTheme to keep track
    of the current high contrast/dark mode preferred color scheme.

    The updated preferred color scheme is used to evaluate the
    prefers-color-scheme media query.

Can't use it as is right now. The proxy is commented out in
`BraveContentBrowserClient::CreateWebSocket`.

    [websocket] Reland: "Split interface mojom::WebSocketClient"

    This CL splits the interface to two parts so that WebRequestProxyingWebSocket or
    extensions proxy only handshake of WebSocket:

    interface WebSocketHandshakeClient {
      OnStartOpeningHandshake(WebSocketHandshakeRequest request);
      OnFinishOpeningHandshake(WebSocketHandshakeResponse response);
      OnAddChannelResponse(string selected_protocol, string extensions);
    };

    interface WebSocketClient {
      OnDataFrame(bool fin, WebSocketMessageType type, array<uint8> data);
      OnFlowControl(int64 quota);
      OnDropChannel(bool was_clean, uint16 code, string reason);
      OnClosingHandshake();
      OnFailChannel(string reason);
    };

    Performance gain of receive-arraybuffer-1MBx100.html:
    Mine: 1050 ms
    ToT : 1221 ms

    Relanding:
     The previous patch was reverted because of a browser test
    of "--disable-features=NetworkService". This patch fixes it to adapt
    a WebRequestAPI test to both expectations.

    Reland "[WebSocket] Add --websocket-renderer-receive-quota-max command line flag."

    Reason for reland: the culprit was not this patch.

    This patch was reverted because of compile failure on android:
    https://chromium-review.googlesource.com/c/chromium/src/+/1660391

    However, relanding this don't cause compile failure.

    [WebSocket] Add --websocket-renderer-receive-quota-max command line flag.

    This patch adds the flag that overrides default threshold value
    that the renderer calls AddReceiveFlowControlQuota() to the browser per
    receiving this amount of data so that the browser can continue sending
    remaining data to the renderer.
    Default value is 32k Bytes.

    The more the value is, browser tends the less stop sending packets
    and then consumes more memory.

    This flag will be used to investigate the performance issue.
    You can use this flag both on chrome and content_shell:
    $ ./chrome.exe --websocket-renderer-receive-quota-max=3000000
    This flag sets the threshold 3M Bytes.

    Implementation detail:
    This patch moves the default value constant from blink to
    net/websockets/websocket_channel.h so that we can pass the command line
    flag to the renderer.
    This change also enables us to modify the value while considering sent buffer
    from a server later on for further optimization.

    Rename WebSocketHandshakeClient messages

    In preparation to removing AddChannelRequest, rename AddChannelResponse
    to OnConnectionEstablished. OnFinishOpeningHandshake has been confusing
    because it doesn't mean successful handshake finish (i.e., connection
    establishment). Rename it to OnResponseReceived. Rename
    OnStartOpeningHandshake to OnOpeningHandshakeStarted for consistency.

    Remove mojom::WebSocket::AddChannelRequest

    ...in order to remove the unnecessary overhead on the browser process
    when downloading / uploading payloads. With this CL, both
    mojom::WebSocket and mojom::WebSocketClient only pass though the proxy
    interface implemented in extensions/browser/api/web_request.

    With this CL,

    1) NetworkContext::CreateWebSocket takes additional parameters. This
    makes the state transition in network::WebSocket a bit simpler.

    2) blink::mojom::WebSocketConnector is introduced.
    mojom::WebSocketConnector::Connector corresponds to
    mojom::WebSocket::AddChannelRequest.

    3) mojom::WebSocket is passed as a parameter of
    mojom::WebSocketHandshakeClient::OnConnectionEstablished.

    4) Instead of mojom::WebSocket, the extensions module now receives
    a function to initiate a WebSocket opening handshake.

    5) ContentBrowserClient::WillCreateWebSocket is split into three:
    WillInterceptWebSocket, GetWebSocketOptions and CreateWebSocket. This
    incurs an additional thread hop, but it will be fixed once the
    extensions module for WebSocket is moved to the UI thread.

    This improves [1] in my environment.

    With the change   : 389MB/s

This commit is a squash of 4 commits from #3281.

- Fix setting preferred color scheme logic for brave theme change
- Fix system dark mode change affect brave theme on Win10
    When brave theme is set to dark or light, system dark mode change
    should not affect brave theme.
- CleanUp: Delete SystemThemeSupportDarkMode
    Upstream added ui::NativeTheme::SystemDarkModeSupported().
    Replace ours with upstream one.
- Add dark mode change test by modifying reg value for Windows
    This test can verify whether theme change notification is delivered
    or not.
    If brave theme option is not default, system dark theme change should
    not trigger theme change notificagtion delivery.
