This remove cogl-internal.h in favour of using cogl-private.h. Some
things in cogl-internal.h were moved to driver/gl/cogl-util-gl-private.h
and the _cogl_gl_error_to_string function whose prototype was moved from
cogl-internal.h to cogl-util-gl-private.h has had its implementation
moved from cogl.c to cogl-util-gl.c

Removing CoglHandle has been an on going goal for quite a long time now
and finally this patch removes the last remaining uses of the CoglHandle
type and the cogl_handle_ apis.
Since the big remaining users of CoglHandle were the cogl_program_ and
cogl_shader_ apis which have replaced with the CoglSnippets api this
patch removes both of these apis.

Since the original patch was done after removing deprecated API
this back ported patch doesn't affect deprecated API and so
actually this cherry-pick doesn't remove all remaining use of
CoglHandle as it did for the master branch of Cogl.
Previously the Xlib renderer data was meant to be the first member of
whatever the winsys data is. This doesn't work well for the EGL winsys
because it only needs the Xlib data if the X11 platform is used. The
Xlib renderer data is now instead created on demand and connected to
the object using cogl_object_set_user_data. There is a new function to
get access to it.

Xlib headers define many trivially named objects which can later cause
name collision problems when only cogl.h header is included in a program
or library. Xlib headers are now only included through including the
standalone header cogl-xlib.h.

we've got into a bit of a mess with how we name platform specific
symbols and files, so this is a first pass at trying to tidy that up.
All platform specific symbols should be named like
cogl_<platform>_symbol_name and similarly files should be named like
cogl-<platform>-filename.c
This patch tackles the X11 specific renderer/display APIs as a start.

This adds Xlib and Win32 typesafe replacements for
cogl_renderer_handle_native_event, cogl_renderer_add_native_filter,
cogl_renderer_remove_native_filter. The old functions are kept as an
implementation detail so we can share code.

Instead of using _cogl_xlib_add/remove_filter we now use
_cogl_renderer_add/remove_native_filter. The _cogl_xlib_add_filter API
was only required as a stop gap while EGL support was still in Clutter
because in that case we were using the stub winsys and didn't have a
CoglRenderer.
This removes the redundant _cogl_xlib_trap/untrap_errors functions that
simply wrap equivalent functions in the _cogl_renderer_xlib namespace.
These were originally only required while the EGL winsys was being
handled in clutter and so there wasn't a CoglRenderer in all cases.
Since we no longer have any xlib based backends in Clutter that depend
on the stub winsys in Cogl we can now remove all the special case code
we had for this in cogl-xlib.c
Instead of having cogl_renderer_xlib_add_filter and friends there is
now cogl_renderer_add_native_filter which can be used regardless of
the backend. The callback function for the filter now just takes a
void pointer instead of an XEvent pointer which should be interpreted
differently depending on the backend. For example, on Xlib it would
still be an XEvent but on Windows it could be a MSG. This simplifies
the code somewhat because the _cogl_xlib_add_filter no longer needs to
have its own filter list when a stub renderer is used because there is
always a renderer available.
cogl_renderer_xlib_handle_event has also been renamed to
cogl_renderer_handle_native_event. This just forwards the event on to
all of the listeners. The backend renderer is expected to register its
own event filter if it wants to process the events in some way.
This migrates all the GLX window system code down from the Clutter
backend code into a Cogl winsys. Moving OpenGL window system binding
code down from Clutter into Cogl is the biggest blocker to having Cogl
become a standalone 3D graphics library, so this is an important step in
that direction.
