    Static markup and dead code cull over xkb/.

    The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
    include/xkbsrv.h, and the world updated to look for it in the new place,
    since it made no sense to define server API in an extension header.  Any
    further work along this line will need to do similar things with XKBgeom.h
    and friends.

 * Support for XkbCF has been dropped in XKB extension by X.org
 * Has never been used in recent NXv3 implementations (e.g. X2Go)
 * Config file parsing is error prone, use setxkbmap API instead

                Use C99 designated initializers in dix Replies

    the initializer for the .length element of the xGetPointerMappingReply
    structure uses the value of rep.nElts, but that won't be set until
    after this initializer runs, so we get garbage in the length element
    and clients using it will generally wedge.

    Easy to verify:

            $ xmodmap -pp

    Fixed by creating a local nElts variable and using that.

        This counter exposes the time in milliseconds since the last

        can set an alarm on this counter to find out when the idle time
        reaches a certain value, without having to poll the server.

What actually happened was that MFLAGS were passed-through more
correctly, which forced make into jobserver mode (due to the inclusion
of --jobserver-fds=... in %{_smp_mflags}), but the processes were not
able to read from their FD's, so it defaulted to non-parallel builds
instead.
