Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Rename all symbols in libmp(3) to mp_*, just like Solaris.

The function pow() in libmp(3) clashes with pow(3) in libm. We could
rename this single function, but we can just take the same approach as
the Solaris folks did, which is to prefix all function names with mp_.

libmp(3) isn't really popular nowadays. I suspect not a single
application in ports depends on it. There's still a chance, so I've
increased the SHLIB_MAJOR and __FreeBSD_version.

Join the 21st century: Cryptography is no longer an optional component
of releases. The -DNOCRYPT build option still exists for anyone who
really wants to build non-cryptographic binaries, but the "crypto"
release distribution is now part of "base", and anyone installing from a
release will get cryptographic binaries.

Put chkey(1), newkey(8), and keyserv(8) into the crypto distribution.

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

WARNS=2 fixes. Also, use __FBSDID(), and sort includes.

Fixed bitrot in DPADD in previous commit.

Fixed some style bugs (mainly disorder).

Enable the new libmp in the build, and disable libgmp and its
henchmen.

$Id$ -> $FreeBSD$

Fixed missing DPADD.
Fixed some style bugs while I'm here (don't override the (correct)
default for MAN1).

This commit was generated by cvs2svn to compensate for changes in r26240,
which included commits to RCS files with non-trunk default branches.

Import chkey.

This program is used to change a user's existing public and secret key pair.
