    mesa: do not use _glapi_new_nop_table() for DRI builds

    Commit 4bdbb588a9d38 introduced new _glapi_new_nop_table() and
    _glapi_set_nop_handler() functions in the glapi dispatcher (which
    live in libGL.so).  The calls to those functions from context.c
    would be undefined (i.e. an ABI break) if the libGL used at runtime
    was older.

    For the time being, use the old single generic_nop() function for
    non-Windows builds to avoid this problem.  At some point in the future
    it should be safe to remove this work-around.  See comments for more
    details.

    v2: Incorporate feedback from Emil.  Use _WIN32 instead of
    GLX_DIRECT_RENDERING to control behavior, move comments.
