The C API allows overriding the notification providers and managers for customizing the handling of
notifications. We decided to go for a single manager and a single provider which provide more idiomatic
GObject API - signals.

[GTK] Enable depth 32 for the RedirectedXCompositeWindow
https://bugs.webkit.org/show_bug.cgi?id=139028

On gtk/X11, the layout compositing is done in the web process.
If one needs to handle alpha with the rest of the application
then it is not enough to make to browser's window as RGBA.
The shared redirected window needs to be RGBA as well.
(The shared X composite window between UIProcess and WebProcess).

This allows an end-to-end RGBA solution when the application
wants to interact with the alpha channel at compositing time.
For example for transparent Web UI.

[WK1] new http/tests/notifications/legacy/notification-request-permission-then-navigate.html test is crashing
https://bugs.webkit.org/show_bug.cgi?id=139494

Reviewed by Alexey Proskuryakov.

Call window.open() after the page has been loaded because our test infrastructure
asserts that testRunner.waitUntilDone() must have been called *before* window.open()
is called. Since testRunner.waitUntilDone() is called is js-test-post.js, calling
window.open() after page load fixes the issue.
