5f925a1580 Revert "libgstgl: cocoa, eagl: don't marshal GL calls to the context thread" 
This reverts commit 797d6415df.

We're frozen for 1.8.0 release and this change might have bigger impact.

797d6415df libgstgl: cocoa, eagl: don't marshal GL calls to the context thread 
Execute GL calls without marshalling them to the context thread. In the cocoa
and eagl backends calling gst_gl_context_activate is cheap and therefore calling
it on the current thread and serializing GL calls with a per-context lock is
more efficient (faster and has less overhead) than marshalling everything to the
context thread.

This optimization cuts a large overhead in g_poll (continuously waking up the
context thread) and in g_mutex_*/g_cond_* (waiting for results from the context
thread).

eb14273631 Revert "gl/eagl: try getting a gles3 context" 
This reverts commit 96b9666d59.
This reverts commit d11385d167.

This breaks the texture sharing with the applemedia elements as
CVOpenGLESTextureCache seems to have an arbitrary restriction on GLES2 only.

c97144b23b gl/eagl: Don't make context uncurrent just to make it current again in the next line 
Also binding the framebuffer again is unnecessary then as it was just bound a
few lines before while the context was current.

dbcae77e02 glcontext: pass display to implentation's _new() 
This allows the context to fail creation based on incompatible
display type's. e.g. glx context with an wayland display handle.

34622c3961 gl/eagl: Don't call anything synchronously from the main thread 
This will deadlock if the main thread is the one who creates the GstGLContext.
All things we call from the main thread should be possible from any thread.

This reverts commit 0bff481011.

It wasn't supposed to be merged and also doesn't fix the problem.

6981a8d15b libgstgl: fix rendering on iOS 
Stop assuming that the handle has been set by the time ->create_context is
called. After bc7a7259f3 set_window_handle always
happens after ->create_context in fact.
