r318960 (by dab):

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.

Relnotes: yes

r319545:

Don't execute the TODO cases in a subshell

This messes up the testcase counter, as seen in bug 219756.

PR: 212160, 219756

r319546:

Fix the testplan after ^/head@r318960

The number of executed testcases is 128, not 126.

MFC with: r318960

r319548:

Remove TODO for sub testcases added for bug 212160

On closer inspection, the past failures no longer occur on ^/head.

r321261:

Clean up leading whitespace (convert single column spaces to hard tabs)

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

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

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.
