Remove $FreeBSD$: one-line sh pattern

pkgbase: Put a lot of binaries and lib in FreeBSD-runtime

All of them are needed to be able to boot to single user and be able
to repair a existing FreeBSD installation so put them directly into
FreeBSD-runtime.

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.

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

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

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

- Continue, in case of error.
- Add WARNS?= 6

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

Set WARNS=2 on programs that compile cleanly with it; add $FreeBSD$
where necessary.

Oops. fsync(8) should have been fsync(1). (repo-copied by peter)
Change reference from update(4) to syncer(4).

Add fsync(8). This becomes useful with the advent of MAP_NOSYNC etc.
