296b4251e3 gl: Fix backwards compat GST_GL_TYPE_* functions/macros 
These have to be macros instead of inline function as they must behave
more or less like an integer literal, i.e. include the function call.

abec124f69 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

2aadd7eaf9 glcontext: implement checking whether a context has been shared 
Some operations are unnecessary when running with only a single GL
context.
e.g. glFlush when setting a fence object as the flush happens on wait.

API: gst_gl_context_is_shared

d5996de5d7 glcontext: fix get_current_gl_api on x11/nvidia drivers 
They require to get_proc_address some functions through the

GL library symbol lookup.
