98249a57db gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

564ab3031b gstgl: Add a new window type for WinRT
This is needed for using GstGL with ANGLE as the GLES implementation
in Universal Windows Platform apps that use the Windows Runtime
(WinRT) instead of Win32, which is deprecated and not allowed in
Windows Store apps.

This has been tested with Servo on the Microsoft HoloLens 2, and seems
to work quite well.

0314b482f3 Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

6a37bf9bb9 gl: Don't restore the viewport on function exit
Doing so involves retrieving the current viewport from OpenGL which as
with any glGet operation, is expensive.

This means that the various sinks need to reset the viewport on draw.

In the process, fix resizing on cocoa.

4be04f8315 gl: don't export symbols that are not supposed to be public
Make a bunch of symbols private that are currently leaked
accidentally because they have a gst_* prefix and are used
internally. We mark those we can't make static with
G_GNUC_INTERNAL so that they get hidden with the autotools
build as well (although we could just pass -fvisibility=hidden
there too).

f532e699df gl/window: remove use of main_context_push/pop_thread_default()
No-one's using/depending on it (it would have criticalled and not worked)
and it's causing more problems than it's solving.  Store the GMainContext
in the public struct instead for subclasses to optionally use instead of
relying on the push/pop state to be correct.

7306f2de2c glwindow: move g_main_context_push/pop_thread_default() to run()
Calling g_main_context_push_thread and then g_main_context_invoke()
(used by gst_gl_window_send_message_async()) in the same thread will
cause the invoked function to run immediately instead of being delayed.

This had implications for the creation of the OpenGL context not waiting
until the main loop had completely started up and as a result would
sometimes deadlock in short create/destroy scenarios.

126ee924c0 glwindow: don't use g_thread_join() to join the navigation thread
Using g_thread_join() in _finalize() handlers may result in a deadlock
joining the current thread when the last reference is held by a signal
handler.

e.g.:

error 'Resource deadlock avoided' during 'pthread_join (pt->system_thread, NULL)'

The backtrace looks like this:
[...]

gst_gl_window_x11_finalize ()
g_object_unref ()
g_value_unset ()
g_signal_emit_valist ()

OSX/iOS and possibly other platforms.

1403a6871f glwindow: Hide navigation specific internal API and add API to asynchronously send navigation events
Exposing the navigation thread's main context, GSourceFuncs and structs called
key_event and mouse_event is exposing a bit too much of the internals. Let's
just go with two functions to asynchronously send navigation events on the
window with the same API as the synchronous ones.

63bbe9406a glwindow: add API to request a resize event on the next draw
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.
