Add initial 'cogl' implementation. 'cogl' is a simple abstration
layer over GL and GL/ES used by clutter internally. It should
eventually allow clutter applications to be run on both GL and GL/ES
with just a recompile as well as provide more debugging and potentially
profiling information for GL and GL/ES usage.
This commit contains the initial GL implementation.
