178bbc253d glcontext: keep a ref to the active thread
With the macOS/iOS implementations, the active thread can change
multiple times over the life of a pipeline which would expose a race in
the thread tracking.

Fix by taking a ref on the active thread while the context is active.

22e78529dd gstglcontext: is_shared should return FALSE if no group
If a sub class of GstGLContext does not create a group
then it currently crashes:

0 g_atomic_int_get (&share->refcount)

f22390e46e glcontext: fix race between creation/shutdown
626bcccff9 removed some locks that
allowed the main loop quit to occur before the context was fully
created.

2776cef25d attempted to readd them but
missed the scop of the quit() call.

Also remove the use of g_thread_join() as that's not safe to use when
it's possible to lose the last reference from the GL thread.

db51c90d5d 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.

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

78957c45c2 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.
