        WebDriver: ensure we close all windows handles when closing the session
        https://bugs.webkit.org/show_bug.cgi?id=176508

        Reviewed by Brian Burg.

        The spec says that when closing the session all top level browsing contexts should be closed. We are currently
        checking if we have an active top level browsing context and then we try to close it before trying with the
        rest. It can happen that we are in an inconsistent state, for example if the current top level browsing context
        has been closed by JavaScript or another action and the user didn't switch to another one before closing the
        session. In such case, closing the session will fail with NoSuchwindow and any other window open will not be
        closed. It's safer to always ask for all window handles and close them, which is what the spec says too.

        (WebDriver::firstWindowHandleInResult): Helper class to get the first window handle in the result array.

        WebDriver: handle click events on option elements
        https://bugs.webkit.org/show_bug.cgi?id=174710
        <rdar://problem/33459305>

        Reviewed by Brian Burg.

        Option elements are considered as a special case by the specification. When clicking an option element, we
        should get its container and use it when scrolling into view and calculating in-view center point instead of the
        option element itself. Then, we should not emulate a click, but change the selected status of the option element
        like if it were done by a user action, firing the corresponding events. Now we check whether the element is an
        option to call selectOptionElement() or performMouseInteraction().

        WebDriver: wait until navigation is complete before running new commands and after a click
        https://bugs.webkit.org/show_bug.cgi?id=174670

        Reviewed by Brian Burg.

        We are already waiting for navigation to complete after navigation commands (go, back, forward, refresh), but
        the spec says we should always wait before executing a new command and also after a click. This is causing test
        testShouldBeAbleToNavigateBackInTheBrowserHistoryInPresenceOfIframes to sometimes fail, because it does .click()
        + .title and expects the title to tbe the one of the page loaded by the click. Since the load happens very fast,
        the test usually passes, but in a real case with a slower load, the title of the previous page will be returned
        most of the times.

        WebDriver: correctly handle main frame handles
        https://bugs.webkit.org/show_bug.cgi?id=174668

        Reviewed by Brian Burg.

        When I switched to use std::optional instead of empty strings for the browsing contexts in WebDriver, I forgot
        that automation uses empty string for frames to refer to the main frame. We should handle that case, because we
        are currently considering empty strings as valid browsing context. It's not a big deal because Automation
        converts back the empty string received to the main frame, though. We should also ensure we close the current
        browsing context when switching to a new top level browsing context. This patch adds to helper private methods
        to switch browsing contexts that deal with the special cases.

        Add initial implementation of WebDriver process to run the HTTP server
        https://bugs.webkit.org/show_bug.cgi?id=166682

        Reviewed by Brian Burg.

        Add WebDriver process that runs the HTTP server and implements an initial set of commands. Most of the code is
        cross-platform, only the HTTP server implementation, the code to launch the browser and the communication with
        the remote inspector requires platform specific code. This patch includes the GTK port implementation, using
        libsoup for the HTTP server, and GLib for launching the browser and communicating with the remote
        inspector. This implementation follows the w3c spec (https://www.w3.org/TR/webdriver) as close as possible, but
        using the official selenium python tests as reference.
