Remove $FreeBSD$: one-line .c comment pattern

Remove /^/[*/]\s*\$FreeBSD\$.*\n/

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.

Allow user to omit font size specification when loading a font. In addition
the following fixes had been made:

- check the size of the font being loaded and compare it with possible sizes
to minimise possibility of loading something that is not a fontfile at all
and turning console screen into garbage;

- prevent buffer overflow (and coredump as a result ) when loading valid
uuencoded file with size that exceeds allocated buffer;

- correct and improve several error messages.

Add a -s option for setting the current vty. This should make
life easier if a PS/2 mouse locks up the keyboard (frequent-ish,
but not repeatable).
Tidy up code (a bit) and make it -Wall

Is this a 2.2 candidate ? (although it doesn't -Wall in 2.2 because
of the lack of sys/sysproto.h
