glapi: Allow normal entry points to be skipped.

Reorganize glapitemp.h such that it is possible to skip normal entry
points or protocol entry points by defining
_GLAPI_SKIP_NORMAL_ENTRY_POINTS or _GLAPI_SKIP_PROTO_ENTRY_POINTS.

Protocol entry points are those with different GLX protocols.  They are
skipped in libglapi.a when GLX_INDIRECT_RENDERING is defined.
