9dd4f40ad6 gl: Let gst_gl_context_get_thread() return a new reference to the GThread 
Otherwise it might go away in the meantime and the caller has some random pointer.

61b95b0300 glcontext: implement the debug callback 
For both GL_KHR_debug and ARB_debug_output.  This allows us to
receive errors and other hints from the GL instead of querying after
every GL operation.

14f844e1e9 glcontext: Try to open lib{EGL|GL|GLESv2}.so.1 before lib{EGL|GL|GLESv2} 
Fixes issues with .so (without numbering) being installed for development
(such as from mesa-dev) but actual driver (with numbering) coming from
some other place (like nvidia drivers)

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.

790f34c7a6 gl: fix detection of extensions with GL versions < 3 
Mesa, for example returns valid pointers for glGetIntegerv and
glGetStringi even if the gl version is less than that required for
both those functions to supposedly exist.
