b9cdc9d4b0 glcontext: correct precondition for get_gl_version 
The intention was to assert if both maj and min were NULL (as there would be no
point calling the function).  Instead if either maj or min were NULL, the assert
would occur.

Fix that.

8a67cd90b3 glcontext: fix get_current_gl_api() on win32 
Another case of incorrect calling conventions.

Using this function on win32 would corrupt the stack pointer and end in
massive hilarity.

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

2c0aca52a8 gstglcontext: micro optimization to gst_gl_context_thread_add 
Invoke the callback right away when called on the context thread. Removes
overhead when nesting libgstgl calls (for example when working with the sync
meta).

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.

85834d6bbc glcontext: add specific error message when missing GL_SHADING_LANGUAGE_VERSION 
GL_SHADING_LANGUAGE_VERSION was introduced since ES 2.0, but in some
android emulator doesn't support this feature. To prevent confusion for
developer, the error message need to be more clear.

be9ad5eeb2 glcontext: track sharedness with a cookie 
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.
