c3612847ef glimagesink: don't make gst_glimage_sink_handle_events call _ensure_gl_setup
gst_glimage_sink_handle_events can be called from the overlay interface and from
the main thread before GL is setup. Before this change, that would call
_ensure_gl_setup() and deadlock on OSX.

Change things so that it's always safe to call gst_glimage_sink_handle_events()
without stuff deadlocking.

ab8990c89f glimagesink: fix possible deadlock on osx
Remove gst_glimage_sink_handle_events call in gst_glimage_sink_init. It was
unnecessary and when the element was instantiated from the main thread, caused a
deadlock in OSX creating the context (thread).

0fa95fe809 glimagesink: resize the viewport correctly on a caps change
with force-aspect-ratio=true, if the width or height changed, the
viewport wasn't being updated to respect the new video width and height

Otherwise, it is only possible for the sink pads and the src pads to

to another feature so support that.

6491af9ffc glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.
