Almost nothing draws attributes directly and for those things that do
it's trivial to adapt them to instead draw via the cogl_primitive api.
This simplifies the Cogl api a bit.

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.

cogl_meta_texture_foreach_in_region() now directly supports
CLAMP_TO_EDGE wrap modes. This means the cogl_rectangle code will be
able to build on this and makes the logic accessible to anyone
developing custom primitives that need to support meta textures.

CoglMetaTexture is an interface for dealing with high level textures
that may be comprised of one or more low-level textures internally. The
interface allows the development of primitive drawing APIs that can draw
with high-level textures (such as atlas textures) even though the
GPU doesn't natively understand these texture types.
There is currently just one function that's part of this interface:
cogl_meta_texture_foreach_in_region() which allows an application to
resolve the internal, low-level textures of a high-level texture.
cogl_rectangle() uses this API for example so that it can easily emulate
the _REPEAT wrap mode for textures that the hardware can't natively
handle repeating of.
