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.

r319546:

Fix the testplan after ^/head@r318960

The number of executed testcases is 128, not 126.

Remove TODO for sub testcases added for bug 212160

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

- Remove unnecessary TESTSDIR setting
- Use SRCTOP where possible for clarity

Remove unused variable (SRCDIR)

MFC various moves of tools/regressions/ tests to the new infrastructure.

- r263220 Migrate tools/regression/sbin/ to the new tests layout.
- r263222 Add Makefile missed in r263220.
- r263226 Migrate tools/regression/{usr.bin/lastcomm,usr.sbin}/ to the new tests layout.
- r263227 Migrate most of tools/regression/usr.bin/ to the new tests layout.
- r263345 Expand tabs that sneaked in into spaces.
- r263346 Migrate tools/regression/usr.bin/make/ to the new tests layout.
- r263348 Add Makefiles missed in r263346.
- r263351 Migrate tools/regression/usr.bin/pkill/ to the new tests layout.
- r263388 Mark multi_test as requiring /usr/share/dict/words.
- r263814 Fix path to the run.pl script to let these tests run.
- r264742 Prevent building tests when bootstrapping make.

This is 'make tinderbox' clean.

Migrate tools/regression/{usr.bin/lastcomm,usr.sbin}/ to the new tests layout.

This change was originally going to only migrate the usr.sbin tests but, as
it turns out, the usr.sbin/sa/ tests require files from usr.bin/lastcomm/
so it's better to just also migrate the latter at the same time. The other
usr.bin tests will be moved separately.

To make these tests work within the test suite, some of them have required
changes to prevent modifying the source directory and instead just rely on
the current directory for file manipulation.

Spelling fixes for tools/

Add some $FreeBSD$ tags so svn will allow the commit.

Expand / correct newsyslog regression tests:
- Test newslog with clasic naming of rotates files to actually test
the correct number of log files as newsyslog now does the correct
thing post r220926.
- Add some more newsyslog tests which tests keeping 0, 1, and 2
logfiles.

Add regression tests for newsyslog. These are far from a complete
test of newsyslog, as they were mainly made to test 'newsyslog -t',
but they do test the basic functionality.

The test 'framework' was based on dds@'s code in
src/tools/regression/bin/mv/.

Note that currently these tests are not fully correct for the
non-timestamp based rotation case, as it seems like newsyslog actually
by default keeps a file too much around.
