This adds compiler symbol deprecation declarations for old Cogl APIs so
that users can easily see via compiler warning when they are using these
symbols, and also see a hint for what the apis should be replaced with.
So that users of Cogl can manage when to show these warnings this
introduces a scheme borrowed from glib whereby you can declare what
version of the Cogl api you are using:
COGL_VERSION_MIN_REQUIRED can be defined to indicate the oldest Cogl api
that the application wants to use. Cogl will only warn about
deprecations for symbols that were deprecated earlier than this required
version. If this is left undefined then by default Cogl will warn about
all deprecations.
COGL_VERSION_MAX_ALLOWED can be defined to indicate the newest api
that the application uses. If the application uses symbols newer than
this then Cogl will give a warning about that.
This patch removes the need to maintain the COGL_DISABLE_DEPRECATED
guards around deprecated symbols.
This patch fixes a few uses of deprecated symbols in the examples/

This fixes some problems which were stopping --disable-glib from
working properly:
• A lot of the public headers were including glib.h. This shouldn't be
necessary because the API doesn't expose any glib types. Otherwise
any apps would require glib in order to get the header.
• The public headers were using G_BEGIN_DECLS. There is now a
replacement macro called COGL_BEGIN_DECLS which is defined in
cogl-types.h.
• A similar fix has been done for G_GNUC_NULL_TERMINATED and
G_GNUC_DEPRECATED.
• The CFLAGS were not including $(builddir)/deps/glib which was
preventing it finding the generated glibconfig.h when building out
of tree.

To delimit which symbols were considered experimental we used to use
some preprocessor defines to gives experimental symbols an _EXP suffix
so that anyone monitoring the ABI for changes would easily be able to
discount changes made to clearly experimental functions.
These days we simply rely on the gtk-doc "Stability: unstable"
annotation to serve this purpose because changing the actual symbol name
made it slightly more awkward to debug Cogl using GDB and was an extra
mechanical step we decided we could do without.
This patch removes the last remaining _EXP suffix defines in Cogl

The cogl.h header is meant to be the public header for including the 1.x
api used by Clutter so we should stop using that as a convenient way to
include all likely prototypes and typedefs. Actually we already do a
good job of listing the specific headers we depend on in each of the .c
files we have so mostly this patch just strip out the redundant
includes for cogl.h with a few fixups where that broke the build.

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.

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.
