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.

If a sub class of GstGLContext does not create a group
then it currently crashes:
0 g_atomic_int_get (&share->refcount)
1 _context_share_group_is_shared (context->priv->sharegroup)
2 gst_gl_context_is_shared
3 _default_set_sync_gl

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.

626bcccff9 removed some locks that
allowed the main loop quit to occur before the context was fully
created.
2776cef25d attempted to readd them but
missed the scop of the quit() call.
Also remove the use of g_thread_join() as that's not safe to use when
it's possible to lose the last reference from the GL thread.

It's been removed and thus compiling anything against GstGLMemoryEGL
would error with:
In file included from gstomxvideodec.c:41:0:
usr/include/gstreamer-1.0/gst/gl/egl/gstglmemoryegl.h:32:41: fatal error: gst/gl/egl/gstglcontext_egl.h: No such file or directory

Otherwise, when the application reuses the same UIView, we were getting
draw notifications on the previous view/layer's which weren't valid anymore
and were referencing pointers that had been freed.

- xcb is supposedly thread-safe!
videotestsrc ! glimagesink now doesn't spuriously result in a
'call XInitThreads()' error however if anybody else is using X11,
then XInitThreads() still needs to be called and multiple glimagesink's
still need XInitThreads().
Everything still takes libX11 handles as they are compatible with the xcb
variants. Unfortunately we cannot move fully over to xcb due to GLX being
entirely based on Xlib. It's also impossible to transform a xcb_connection
to a Display which means we require X11 handles.
The spec allows the core/compatibility profiles to be used
with #version 150.
Also tighten up the tests to check for default profiles being chosen
correctly.
The change to use GST_EXPORT for symbols under Windows requires
GST_EXPORTS for internal use, and that is also needed under Autotools.
The same thing is done for gstreamer-1.0.dll in -core.
The calling convention may be deprecated, but we still need it for
OpenGL. The build issue was caused by an incorrect syntax being used for
the WINAPI (__stdcall) prototype in function pointers which was accepted
by GCC but is rejected by MSVC.
