random(6): produce random results

This program is trash and there's no reason to keep it in base. But as long as
we're shipping a silly program named 'random', let's actually make it random.

Final step of eliminating the "games" distribution: Merge src/games
(or what's left of it, at least) into src/usr.bin.

This change will not be MFCed.

All cosmetic.
1) Rename RANDOM_MAX to RANDOM_MAX_PLUS1 to not confuse with random()'s max
2) Use calloc() instead of zeroing fields explicitly
3) "too many lines" -> "too many delimiters" for err()

I was confused a bit by the wrong construction with RAND_MAX
used in randomize_fd.c.
Although the max value is the same currently, RAND_MAX is for rand(),
not for random().
So move RANDOM_MAX const t

So move RANDOM_MAX const to the common file now, make it UL and
use in randomize_fd.c too.
(in any case its old value was 1 less then must be, as noted in
the prev. commit)

bytes back than the buffer, but it isn't EOF[2]. random(6) extensively
tested and believed to be bug free (save performance for large files).

Update random(6) to have the ability to randomize a file/stdin based
off of lines or words. See the man page for details.
