Removed COGLhandle and changed shader and program functions to be

wrapped in reference-counted CoglHandles instead.

	* clutter/cogl/gl/cogl-shader.c: 
	* clutter/cogl/gl/cogl-shader.h: 
	* clutter/cogl/gl/cogl-program.c: 
	* clutter/cogl/gl/cogl-program.h: 
	New files to hold the shader and program functions.

	* clutter/cogl/gl/cogl.c: Removed shader and program functions.

	* clutter/cogl/common/cogl-handle.h: New header to define
	COGL_HANDLE_DEFINE which helps build functions to create
	reference-counted handles. This reduces the amount of duplicated
	code.

	* clutter/cogl/gl/cogl-texture.c: 
	* clutter/cogl/gles/cogl-texture.c: 
	* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE
	from cogl-handle.h to avoid duplicating some of the common code.

	* clutter/cogl/gles/cogl-defines.h.in: 
	* clutter/cogl/gl/cogl-defines.h.in: Removed COGLhandle

	* clutter/cogl/gl/cogl-context.h: Added handle arrays for programs
	and shaders.

	* clutter/cogl/gl/cogl-context.c (cogl_create_context): Added
	initialisers for shader_handles and program_handles.
	(cogl_destroy_context): Added calls to g_array_free for all handle
	arrays.

	* clutter/cogl/gl/Makefile.am (libclutter_cogl_la_SOURCES): Added
	cogl-{program,shader}.{c,h}

	* clutter/cogl/common/Makefile.am
	(libclutter_cogl_common_la_SOURCES): Added cogl-handle.h

	* clutter/cogl/gles/cogl.c:
	* clutter/cogl/cogl.h.in: Programs and shaders are now wrapped in
	CoglHandles instead of COGLhandles. cogl_program_destroy and
	cogl_shader_destroy is now replaced with cogl_program_unref and
	cogl_shader_unref. cogl_program_ref and cogl_shader_ref are also
	added.

	* clutter/clutter-shader.c: Converted to use CoglHandles for the
	programs and shaders instead of COGLhandles.

	* cogl/cogl-sections.txt: Added cogl_shader_ref,
	cogl_shader_unref, cogl_is_shader, cogl_program_ref,
	cogl_program_unref, cogl_is_program and cogl_is_offscreen.
