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.
