Remove $FreeBSD$: one-line sh pattern

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

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.

Add a warning regarding localhost-only listening daemons inside jails.
Apparently binding only to 127.0.0.1 inside of a jail actually binds
to the jail IP address as well (in effect, bind to all available
interfaces in the jail).

Add Id keywords

added two new files: allowed_domains.txt and allowed_ips.txt.
domains/ips listed in these files are *NOT* filtered,
even if listed in domains.txt or ips.txt.

someone added netcom.com to the domains.txt file,
resulting in all mail from netcom.com being blocked.

- Fix some very minor typos.

improve anti-spam rulesets: check_relay, check_mail, check_rcpt.
break each ruleset into identified sections. (called groups).
note which groups can be reordered.
each group accepts and returns the same strings,
as much as possible.
reactivate Paul Vixie's RBL (in check_mail)
add rules to limit mail relaying to a list of hosts and domains
in the R class (check_rcpt, not active on hub.freebsd.org)
