Remove $FreeBSD$: one-line .c pattern

When parsing a rule to rotate log files on a specific week day,
parseDWM() can advance the time to the next week. If the next week is
in the next month, then tm_mon is incremented. However, the increment
was failing to handle the wraparound from December to January, so when
parsing a rule during the last week of the December, the month would
advance to month 12. This triggered an out-of-bounds read of the
mtab[] array in days_pmonth() after parseDWM() returned. To fix,
this change resets the month to January and increment the year when
the month increment wraps.

The default rule for /var/log/weekly.log triggers this during the
last week of December each year.

newsyslog: Add fallthrough comments to appease Coverity.

Add newsyslog capability to write RFC5424 compliant rotation message.

This modification adds the capability to newsyslog to write the
rotation message in a format that is compliant with RFC5424. This
capability is enabled on a per-log file basis through a new value
("T") in the flags field in newsyslog.conf. This is useful on systems
that use the RFC5424 format for log files so that the rotation message
format matches that of the other log messages. There has been recent
mention of adding an RFC5424 compliant mode to syslogd and at least
one alternative system log daemon (rsyslogd) that already has the
capability to use that format.

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.

Drop the include for <stdint.h>, it was only needed when this was
using __DECONST() for something, and that reference has been removed.

Restructure the time processing routines, mainly to fix up the
"will trim at" message printed when the user requests '-v'. The
previous code would often print the wrong time, such as:
On Sept 22, run: newsyslog -nv /var/log/wtmp
And see: will trim at Mon Sep 1 05:00:00 2003
correct msg: will trim at Wed Oct 1 05:00:00 2003

Correct the calculation of "a leap year" in parseDWM. The calculation
would only match a leap year every 400 years. The parseDWM code first
showed up in April 2000, so the first time this bug would cause any
confusion is in Feb 2004.

Move the parse8601 and parseDWM routines into a new ptime.c file. The
only code-change is to add a "next_time" parameter to both routines (and
that is not used yet). A later update will make "next_time" more useful.
