Clean up and add some test cases for ALU instructions.

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.

Correct copyright date in the BPF regression test.

Adjust BPF JIT compiler regression tests to catch up with r199603.

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

Merge local copy of bpf_validate() with bpf_filter.c.

Merge bpf_filter.c r182425 and add test cases for jump range checks.

While I am here, fix stupid typos in test0080.h and make it JIT compiler only.

Move comments to the right places.

Merge bpf_filter.c r182412 and remove additional local checks.

While I am here, use more realistic value for illegal code test case.

Merge bpf_filter.c r182380 and remove additional local checks
for BPF_STX and BPF_LDX|BPF_MEM instructions.

Add a test case for null filter.

Add more test cases for invalid instructions and add comments
about bpf_validate(9) issues.

Remove some hacks from regression test since bpf_filter.c builds fine now.

Add a trivial bpf filter benchmark.

Use sys/net/bpf_jitter.c instead of rolling our own version
since it is compilable on user land now.

Reflect sys/net/bpf_jitter.h changes to regression test.

Add simple bpf(9) regression tests and test cases.
