7f59cefafb glcontext/cocoa: handle sending one message during shutdown
gst_gl_window_quit() will attempt to send a message but will be called
from GstGLContext's finalize handler and so the weak ref that backs
gst_gl_window_get_context will return NULL as it has already been
cleared.  We need that context in send_message_async to decide whether
to run the provided callback immediately or queue in GCD

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.

d75eb628d6 gl/cocoa: keep refs over async operations
Avoids dereferencing dead objects

What happens in the autovideosink case is that context 1 is created and
destroyed before all the async operations hae executed on the associated
window.  When the delayed operations execute, they then reference dead
objects and crash.

We fix this by keeping refs over all async operations so the object
cannot be deleted while async operations are in flight.

7b42f26b80 applemedia/gl: Update code to use ARC
All code interacting with Objective-C objects should now use Automated
Reference Counting rather than manual memory management or Garbage
Collection. Because ARC prohibits C-structs from containing
references to Objective-C objects, all such fields are now typed
'gpointer'. Setting and gettings Objective-C fields on such a
struct now uses explicit __bridge_* calls to tell ARC about
object lifetimes.

90889bc73f libgstgl: cocoa, eagl: don't marshal GL calls to the context thread
Execute GL calls without marshalling them to the context thread. In the cocoa
and eagl backends calling gst_gl_context_activate is cheap and therefore calling
it on the current thread and serializing GL calls with a per-context lock is
more efficient (faster and has less overhead) than marshalling everything to the
context thread.

This optimization cuts a large overhead in g_poll (continuously waking up the
context thread) and in g_mutex_*/g_cond_* (waiting for results from the context
thread).

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.

0c459222f8 gstglwindow_cocoa: fix slow render rate
In gst_gl_window_cocoa_draw we used to just call setNeedsDisplay:YES. That was
creating an implicit CA transaction which was getting committed at the next
runloop iteration. Since we don't know how often the main runloop is running,
and when we run it implicitly (from gst_gl_window_cocoa_nsapp_iteration) we only
do so every 200ms, use an explicit CA transaction instead and commit it
immediately. CA transactions nest and debounce automatically so this will never
result in extra work.

Depending on the platform, it was only ever implemented to 1) set a

Instead, provide a set_preferred_size () that elements/applications
can use to request a certain size which may be ignored for
videooverlay/other cases.
