correctly rather than all to one file. Patch from Mike Castle

Modify the regex handling so that we can match fortunes in rot13'ed
databases (rot13 the pattern and maintain a second compiled pattern)
and rot13 the rot13'ed fortune before output.
Move the rot13 code to a function since it's now used in three places
instead of just one.
Initialize posfile in one place since it appears to get used without
being initialized when using debugging.
Make a *slight* improvement to the random seeding by squaring the pid
and then xor'ing against the current time, since just xor'ing the time
with the pid will not change if they both advance by one from "odd" to
"even".
Provide a RE_OK() macro that tests if the current compiled pattern
works and a RE_ERROR() macro that prints what went wrong as well
as the particular RE implementation can handle.

This merges in all such remaining changes from the Linux port of the
NetBSD games, except in hunt (where substantial changes from OpenBSD
need to be looked at).
Most noreturn attributes were previously added in bin/6144, with some
others that were missed then in bin/8082. Previous `unused'
attributes were covered in bin/6557, bin/8058 and other PRs (all these
PRs have already been handled and closed).

As soon as POSIX regular expressions are integrated into libc, -lgnuregex
will be going away. Fortune use the old re_comp() & re_exec() regex
routines that are provided by -lcompat.
