This adds the framework needed to check for winsys specific extensions (such as GLX extensions) using a similar mechanism to the cogl-feature-functions header. There is a separate cogl-winsys-feature-functions header which will contain macros to list the extensions and functions. cogl_create_context_winsys now calls _cogl_feature_check for each of these functions. _cogl_feature_check has had to be changed to accept the driver prefix as the first parameter so that it can prepend "GLX" rather than "GL" in this case.
