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.

Correct a few more definitions, capitalize header fields consistently.

Clarify ~. escape definition, remove duplicate entry, and shorten a
definition.

Add support for ~_, ~x, ~i, ~a, ~A, ~<, and ~r! tilde-escapes. Improve
tilde-escapes documentation.

Teach boring old mail(1) about the use of the REPLYTO environment
variable which is de-facto standard for MUAs.

Teach bomail to generate an in-reply-to header so threading MUAs and
mail->news gateways won't lose context.

While i was at it, removed two gratuitous standard violations for
functions starting with an underscore.
