Remove $FreeBSD$: one-line sh pattern

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

Enhance the 'ps' command so that it prints a line per proc and a line
per thread, so that instead of repeating the same info for all threads
in proc, it would print thread specific info. Also includes thread number
that would match 'info threads' info and can be used as argument for
thread swithcing with 'thread' command.

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.

Remove the uarea column from the DDB 'ps' display, and from grog's gdb
scripts.

Rename "msgbuf" to "dmesg", a more easily remembered name.
"Fix" documentation by removing periods and commas.

Remove calls to 'y' macro.

Remove current implementation of kldstat macro.

Add new kldstat, kldstat-v and kernel macros. The kldstat macro is
functionally equivalent to the previous implementation, but it looks
prettier and it matches the kldstat-v macro better. kldstat-v gives
output similar to userland kldstat -v (note lacking space), and kernel
loads a new kernel and dump.

Add documentation for previously undocumented macros, and correct
existing documentation. This is not made any easier by the
brain-damaged format required for the documentation: one line, no full
stops or commas.

Make defproc work.

Get the manual section number for kldstat(8) right. Comment change only.

Add macros for kernel debugging. These have been around for a
while, and they will need some more tuning before they're really
useful, but at the moment they're better than nothing.
