Remove $FreeBSD$: two-line .h pattern

Remove /^\s*\*\n \*\s+\$FreeBSD\$$\n/

Use '%zu' and '%zd' as appropriate for size_t / ssize_t.

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.

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

Update udpzerobyte to understand that passing 0 as a length to recv(2)
will cause it to return 0, not EAGAIN.

Add UNIX domain socket support to udpzerobyte, which suggests this
regression test should be moved to the general sockets test area rather
than netinet.

Add IPv6 support to zero-size UDP transmit/receive test.

Regression test for the loopback handling of zero-length UDP packets, which
should be delivered but without payload.
