Separate out CoglClipStackState from cogl-clip-stack.c CoglClipStackState has now been renamed to CoglClipState and is moved to a separate file. CoglClipStack now just maintains a stack and doesn't worry about the rest of the state. CoglClipStack sill contains the code to flush the stack to GL.

Fixes for --disable-glib 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. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 4138b3141c2f39cddaea3d72bfc04342ed5092d0)

COGL_END_DECLS
cogl: Implement retained clip stacks This adds three new internal API functions which can be used to retain the clip stack state and restore it later: _cogl_get_clip_stack _cogl_set_clip_stack _cogl_clip_stack_copy The functions are currently internal and not yet used but we may want to make them public in future to replace the cogl_clip_stack_save() and cogl_clip_stack_restore() APIs. The get function just returns the handle to the clip stack at the top of the stack of stacks and the set function just replaces it. The copy function makes a cheap copy of an existing stack by taking a reference to the top stack entry. This ends up working like a deep copy because there is no way to modify entries of a stack but it doesn't actually copy the data.
