26e6be8fad glcolorconvert: Apply GstVideoOverlayCompositionMeta buffer to converted buffer
Since glcolorconvert creates a new GstBuffer,
without the GstVideoOverlayCompositionMeta data,
it needs to be copied to not be dropped.

78957c45c2 glcontext: track sharedness with a cookie
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.

6db457a7d9 gl: win32: do not call SetParent in release_parent_win_id()
When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

77e1e70fdc gl: win32: fix crash when finalizing GstGLContext
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting
state to READY then setting a window_handle, and go back to NULL state.

886ea15c52 gl: win32: use a GMainContext to dispatch win32 messages
gst_gl_window_win32_send_message_async() could be called before the
internal window is created so we cannot use PostMessage there.

x11 and wayland backends both create a custom GSource for this,
so there is no reason to not do that for win32.

d4894caacf glcontext: require a shader version to initialize.

18b9519a66 glsyncmeta: ensure that the Fence is going to be executed
Otherwise it could stay client side without being submitted to the GL
server resulting in another context waiting on a Fence that will never
become signalled causing a deadlock.

d5e0d435e4 glframebuffer: don't clear the framebuffer
Breaks attempting to blend with the destination buffer and should be done
explicitly by the callback anyway.
