Gets the mesh API working with GLES2

Browse Source 
* clutter/cogl/common/cogl-mesh.c:
	Make sure we use the appropriate cogl_wrap_gl* funcs as appropriate

	* clutter/cogl/gles/cogl-gles2-wrapper.c
	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	In our glColorPointer wrapper we needed to mark our color attribute
	as normalized.

	* tests/conform/Makefile.am:
	When creating unit test symlinks we use the -l gtester option to
	list tests, but when using the PVR SDK the test binary also spews
	out some extra info that caused lots of random symlinks to be
	created. We now grep for lines starting with a '/'

	* tests/conform/test-mesh-contiguous.c
	* tests/conform/test-mesh-mutability.c:
	Use cogl_set_source_color instead of directly calling glColor4ub
