Commit 1b2dd815 (Registers gtypes for all public objects and structs)
introduced GCCism's in its use of varargs, which broke the build of Cogl
on other non-GCC compilers, such as Visual Studio.
Define the COGL_GTYPE_DEFINE_BASE_CLASS and COGL_GTYPE_DEFINE_CLASS macros
using ISO-style varargs so that the build of Cogl can be fixed on non-GCC
compilers.
