d4894caacf glcontext: require a shader version to initialize.
It's very near pointless to try our GL implementation without shaders.

03908c679e gldisplay: synchronize the searching and creation of GstGLContext's
Ootherwise we could end up with multiple elements in different chains
each creating a context.  Fixes context creation with glvideomixer.

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.

8c56e1bba7 gl: Try harder to load symbols from the correct place
This commit makes the loading of the GModules threadsafe, and
always first tries to load the symbol for the GL library that
is selected for the current context. Only then it falls back
to looking into the current module (NULL), and only as a last
resort the context specific function (e.g. eglGetProcAddress())
is called.

Also add configure parameters to select the names of the library
modules instead of using the defaults, and let the defaults be
independent of the G_MODULE_SUFFIX.
