* eval.c (eval_init): Make seed argument optional in make-random-state.

* rand.c (make_random_state): Do argument defaulting on seed.
Also, mix getpid() into the seed.
(random_fixnum): Bugfix: do proper defaulting on optional
agument, rather than relying on nil.
(random): Fix 2014-02-05 regression. This was totally broken,
ignoring the random state passed in and using the global
random state. This function must only use the state passed in;
there is no defaulting to the global random state.

* txr.1: Documenting that seed is optional in make-random-state.
Describing what guarantees can be expected with regard to
calls made close together temporally.
