Add includex11dir as a path to the includes, sans X11/.

Turn Xpoll.h into a generated file. In the modular tree, substitute in
    whichever of fds_bits or __fds_bits is being used for the member of
    fd_set on the system; in the monolithic tree, substitute in fds_bits
    unconditionally, as that's the way it was before thanks to
    _XOPEN_SOURCE being defined.
