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.

5f87cc0b65 glcontext: add a method to add a context to another share group
Intended for use with wrapped contexts that are created shared with gst's
gl contexts in order to manage the internal sharegroup state correctly.

e.g. with caopengllayer (which is used in glimagesink and caopengllayersink
on OS X), we create a CGL context from the gst context and the sharing state
was not being correctly set on either GL context and gst_gl_context_is_shared()
was always returning FALSE.

With 11fb4fff80 only flushing with multiple
shared contexts, the required flush was not occuring causing screen
corruption or stuttering.

Note: this didn't affect GST_GL_API=opengl pipelines

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.

66407b9877 glcontext: fix get_current_gl_api on x11/nvidia drivers
They require to get_proc_address some functions through the
platform specific {glX,egl}GetProcAddress rather than the default
GL library symbol lookup.

eba6f6b80f gl/calayer: provide the exact GL api version for the wrapped context
Otherwise we could end up being mistaken for the diference between a
gl3 and a gl2 context resulting in a failure getting the list of
extensions from the wrapped context due to the difference between
glGetString and glGetStringi for the GL_EXTENSIONS token.

1c1084881b Revert "libgstgl: gstglcaopengllayer: set the layer as opaque"
This reverts commit 6f152d381c.

The layer shouldn't be always opaque, it should be made a property.

019367c128 glwindow: remove width/height from _draw()
Depending on the platform, it was only ever implemented to 1) set a
default surface size, 2) resize based on the video frame or 3) nothing.
Instead, provide a set_preferred_size () that elements/applications
can use to request a certain size which may be ignored for
videooverlay/other cases.

0e835bc374 gl/cocoa: move to CGL and CAOpenGLLayer for rendering
Removes the use of NSOpenGL* variety and functions.  Any Cocoa
specific functions that took/returned a NSOpenGL* object now
take/return the CGL equivalents.
