Remove $FreeBSD$: two-line .h pattern

Remove /^\s*\*\n \*\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.

Enhance and expand kernel privilege regression tests in support of
work present in FreeBSD 7.0 to refine the kernel privilege model:

- Introduce support for jail as a testing variable, in order to
confirm that privileges are properly restricted in the jail
environment.

- Restructure overall testing approach so that privilege and jail
conditions are set in the testing infrastructure before tests
are invoked, and done so in a custom-created process to isolate
the impact of tests from each other in a more consistent way.

- Tests now provide setup and cleanup hooks that occur before and
after the test runs.

- New privilege tests are now present for several audit
privileges, several credential management privileges, dmesg
buffer reading privilege, and netinet raw socket creation.

- Other existing tests are restructured and generally improved as
a result of better framework structure and jail as a variable.
For exampe, we now test that certain sysctls are writable only
outside jail, while others are writable within jail. On a
similar note, privileges relating to setting UFS file flags are
now better exercised, as with the right to chmod and utimes
files.

dd a series of regression tests to validate that privilege requirements are
implemented properly for a number of kernel subsystems. In general, they
try to exercise the privilege first as the root user, then as a test user,
in order to determine when privilege is being checked.

Currently, these tests do not compare inside/outside jail, and probably
should be enhanced to do that.
