Add META_MODE support.

Still need to add real targets under targets/ to build packages.

Switch primes(6) from using unsigned long to using uint64_t. This fixes
'limited range of type' warnings about comparisons on 32-bit systems, and
allows 32-bit systems to compute the full range of primes.

Correctly enumerate primes between 4295098369 and 3825123056546413050.

Prior to this commit, primes(6) relied solely on sieving with primes up
to 65537, with the effect that composite numbers which are the product
of two non-16-bit primes would be incorrectly identified as prime. For
example,
# primes 1099511627800 1099511627820
would output
1099511627803
1099511627807
1099511627813
when in fact only the first of those values is prime.

This commit adds strong pseudoprime tests to validate the candidates
which pass the initial sieving stage, using bases of 2, 3, 5, 7, 11,
13, 17, 19, and 23. Thanks to papers from C. Pomerance, J.L. Selfridge,
and S.S. Wagstaff, Jr.; G. Jaeschke; and Y. Jiang and Y. Deng, we know
that the smallest value which passes these tests is 3825123056546413051.

At present we do not know how many strong pseudoprime tests are required
to prove primality for values larger than 3825123056546413050, so we
force primes(6) to stop at that point.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead

For variables that are only checked with defined(), don't provide
any fake value.

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

Last commit was slightly hasty: #include <string.h> is required on
-CURRENT to be WARNS-safe (but not -STABLE for some reason)

Kill obsolete #include <memory.h> which I didn't spot earlier because
it's still in the NetBSD version.

Style fixes to: #include ordering; use const and static; ANSI functions;
various usage synopses; bogus and/or unnecessary casting; exit values;
use LINE_MAX instead of magic numbers; declare extern variables in a
header; add $FreeBSD$ where missing.

Revert the last commit, it made the Bruce filter flip:

PR7402 was even less suitable for committing almost verbatim than at
first appearance. Rev.1.9 of primes.c has at least the following defects.

- no update for man page.
- no update for usage string.
- blowing away of a previous commit to change EOF to -1 in getopt() test.
- blowing away of a previous commit to fix printf format errors.
- new printf format errors.
- one gratuitous ANSIism.
- two style bugs.
- ... and a partition in a pear tree.

Hopefully that's the last of the 64-bit cleaning of src/games. That is,
without adding -Wall to the compiler flags. That's not a pretty sight.

Wargh! Who went and changed all the getopt() comparisons from -1 to
EOF? The getopt(3) manpage clearly states that the return value is *-1*,
not EOF! Besides, getopt(3) isn't reading from a file. :)

Noticed-while: merging to 2.2 (where this is correct).
