Sets the "gfx.webrender.force-disabled" preference to false at start up. This is to accommodate changes in Gecko ESR 91 which will automatically use the Web Render layer manager rather than the Client layer manager unless force to do otherwise using this preference. We currently need the Client layer manager for Sailfish Browser.

Title and description say https://wiki.mozilla.org/Platform/GFX/Quantum_Render has a small hint that a different layer manager needs to be used for webrenderer |

@llewelld pushed sailfishos-esr91 to the original as well. We can do incremental changes that are required for esr91 - pr by pr. Finally at the end create one big PR towards next. I'll create similar bracnhes for qtmozembed, gecko-dev, and embedlite-components. |
Changes to gecko mean there's no use for the "confirm" parameter of the embedui:search "loadxml" message. This change therefore removes it.
The window.setBrowserCover() call causes the browser to hang when rendering with ESR 91. This needs to be fixed, but in the meantime disabling the call prevents the hang from occuring. This change prevents the browser page from being rendered on the app cover.
When a window has the "hidden" flag set, the window will immediately be hidden after creation. In addition, such windows are set not to appear in the tab view and are not saved persistently. As a consequence, such windows aren't available for interaction by the user. This is useful for printing, which needs a window to clone the page content into during the print. This window appears as a blank window to the user during the print. This change allows these windows to be hidden.
Adds DuckDuckGo to the user agent overrides.
Adds code to support the 'external' flag, which tells the gecko engine that a request was triggered by an external application. The flag is used to set the Sec-Fetch-* flags appropriately.

This is an ESR 91 change, so currently in draft to prevent it being merged.
