ntpd(8): Don't use OpenSSL's RAND API

The !USE_OPENSSL_CRYPTO_RAND path uses arc4random_buf() correctly.

In general, we should prefer to avoid things OpenSSL does poorly when a good
alternative exists in libc.

usr.sbin/ntp: don't emit versions w/ make -s

<sys.mk> defines ECHO=echo when not using make -s, and ECHO=true when using
make -s.

export ECHO for ntp products and use it in the mkver script to echo the
version. This suppresses the output as appropriate. ECHO is given a default
value to make sure things still work as expected for anyone that isn't
redefining ECHO.

MK_OPENSSL makes RELEASE_CRUNCH redundant here

Since these things are more completely controlled by the MK_OPENSSL knob, remove
RELEASE_CRUNCH here. It's no longer needed for the release and other users can
use the more proper knob if they so desire.

Fix overlinking again after recent ntp updates
Fix building WITHOUT_OPENSSL

Convert usr.sbin to LIBADD
Reduce overlinking

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

The last big commit: let usr.sbin/ use WARNS=6 by default.

- Import the HEAD csup code which is the basis for the cvsmode work.

Update the various files to sync with vendor import of 4.2.4p5.
sntp includes a copy of libopts in itself in vendor code, rewrite the
Makefile to compile and use only one copy. It is an internal library, not
installed.

NOCRYPT -> NO_CRYPT

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.

Discussed on: freebsd-current, in late April 2004

Include support for NOCRYPT & NO_OPENSSL world.

It does survive « make release ».

Uses an upcoming patch from the vendor branch (ntp-stable) of ntp-keygen.

Follow the trend of moving MAINTAINER lines from Makefile into
src/MAINTAINERS.

These two patches makes it easier to compile custom versions of
NTP on FreeBSD:

The first one allows one to avoid installing the html files.

The second one allows one to override the CLOCKDEFS on the
make command line.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Please welcome the brand new ntp4 daemon & utilities in the FreeBSD tree.
This is the second part of the commit (the third -- link in usr.sbin/Makefile)
will be done after a more complete review by phk & obrien.

NOTE: the number of drivers included in the default configuration is very
minimal, mainly local clocks and the one I use RAWDCF. Anyone wanting to
have a more complete version will find recompilation very easy.

It builds and runs on both alpha & i386. It also does survive "make world".
