Remove unnecessary call to (random t).

Change (random t) to (random), now that the latter is more random.

Change (random t) to (random), now that the latter is more random.

* src/fns.c (Frandom): Set the seed from a string argument, if given.
Remove long-obsolete Gentzel cruft.
* src/lisp.h, src/sysdep.c (seed_random): Now takes address and size, not long.
(init_random): New function.
