    Random fixes. E.g., (random) never returned negative values. · d8ed26bd

    * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
    subseconds part to the entropy, as that's a bit more random.
    Prefer signed to unsigned, since the signedness doesn't matter and
    in general we prefer signed.  When given a limit, use a
    denominator equal to INTMASK + 1, not to VALMASK + 1, because the
    latter isn't right if USE_2_TAGS_FOR_INTS.
    * sysdep.c (get_random): Return a value in the range 0..INTMASK,
    not 0..VALMASK.  Don't discard "excess" bits that random () returns.
