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.

50a11e4a77 gl/cocoa: Disable hack for NSApp iteration with a special #define 
The hack causes deadlocks and other interesting problems and it really
can only be fixed properly inside GLib. We will include a patch for
GLib in our builds for now that handles this, and hopefully at some
point GLib will also merge a proper solution.

A proper solution would first require to refactor the polling in
GMainContext to only provide a single fd, e.g. via epoll/kqueue
or a thread like the one added by our patch. Then this single
fd could be retrieved from the GMainContext and directly integrated
into a NSRunLoop.

eeda7a29ce glbufferpool: Always recalculate buffer size 
Actually we should always recalculate buffer size since our buffer size
even when not-padded is smaller for many sub-sampled formats. This is

45ac36ca26 glmemory: Handle upload/download flags from map 
Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

6bb113f685 gl: add a sync meta for synchronizing across GL contexts 
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.

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.

f803a9e746 GstGLWindow: Introduce navigation thread 
This thread dispatches navigation events. It is needed to avoid deadlocks
between window backend threads that emit navigation events (e.g. X11/GMainLoop
thread) and consumers of navigation events such as glimagesink, see
https://bugzilla.gnome.org/show_bug.cgi?id=733661

GstGlWindow_x11 thread is changed to invoke the navigation thread for navigation
dispatching, instead of emiting the event itself. Othe backends beside X11 do
not dispatch navigation events yet, but should use this thread when dispatching
these events in the future.

The navigation thread is currently part of GstGLWindow and not implemented in
separate subclasses / backends. This will be needed in the future.

gst_gl_window_x11_get_surface_dimensions is also changed to use a cached value
of the window's width, height. These values are now retrieved in the X11
thread, function gst_gl_window_x11_handle_event. This change is needed because
otherwise the XGetWindowAttributes gets called from the navigation thread,
leading to xlib aborting due to multithreaded access (if XInitThreads is not
called before, as is the case for gst-launch)

We cannot do it as the winsys may crash if we initialize too late.

Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts.  These GL contexts are generally
accessed from different threads.  Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur.  This concurrent access could result in crashes or abortion
by the winsys (xcb).

b84a2eaf9f gl: rename platform cocoa to cgl 
Before:
GST_GL_PLATFORM=cocoa GST_GL_WINDOW=cocoa
gst-launch-1.0 videotestsrc ! glimagesink

After:
GST_GL_PLATFORM=cgl GST_GL_WINDOW=cocoa
gst-launch-1.0 videotestsrc ! glimagesink

but still pass --enable-cocoa to configure script
because currently it can only be used with cocoa API.

We could later have cgl/gstglcontext_cgl.h that manages
a CGLContextObj directly and cocoa/gstglcontext_cocoa.h
would just wrap it.
So that it could be used with other Apple's window APIs.

313dfbb500 gl/upload: switch the 'master' texture for YUY2, UYVY 
From d4bcef3204 on, using a RGBA
texture to hold the data causes the glmemory to have half width
and a scaling of [2, 1].  Using a LA texture solves this problem
however cannot be attached to the framebuffer for copying into
a RGBA texture.  Which will be solved by moving to EXT_texture_rg.
