Some changes to make COGL pass distcheck with Automake 1.11 and anal-retentiveness turned up to 11. The "major" change is the flattening of the winsys/ part of COGL, which is built directly inside libclutter-cogl.la instead of an intermediate libclutter-cogl-winsys.la object. Ideally, the whole COGL should be flattened out using a quasi-non-recursive Automake layout; unfortunately, the driver/ sub-section ships with identical targets and Automake cannot distinguish GL and GLES objects.
