cogl: Introduce the GE_RET() debug macro

Browse Source 
Some GL functions have a return value that the GE() macro is not able to
handle. Let's define a new Ge_RET() macro which will be able to handle
functions such as glMapBuffer().

While at it, removed the unused variadic dots to the GE() macro.
