glapi: Move public function/variable declarations to glapi.h.

glapi defines an interface that is used by DRI drivers.  It must not be
changed in an ABI incompatible way.  This commit moves all
functions/variables belong to the interface to glapi.h.  Instead of
including u_current.h from glapi.h, u_current.h now includes glapi.h.
