Merge head r232686 through r233825 into projects/pf/head.

Don't run through time checks when entry is definitely oversized. This
leads to newsyslog rotating on (size OR time) if both are specified.

Further fix a typo and spelling classic correctly in function names,

Replace index() and rindex() calls with strchr() and strrchr().

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

Fix an old bug in newsyslog where we kept one log file more than was
requested in newsyslog.conf. This was only the case using the non-time
based filenames (.0, .1, .2 etc.).

The change also makes newsyslog clean clean up the old extra logfile so
users don't end up with a single stale logfile which won't be rotated
out.

This change also cleans up some code a bit to avoid more copy / paste
code and removes some old copy / paste code in the process.

Add support for creating the archived log filenames using a time-stamp
instead of the traditional simple counter.

Using the time-stamp based file-names, once a log file is archived, it
will not change name until it is deleted. This means that many backup
systems will only perform one backup of the archived log file, instead
for performing a new backup of the logfile upon each logfile rotation.

This implementation is separate from the patches in the mentioned PR,
as I wasn't aware of the existence of the PR until after I had
implemented the same functionality as the patches in the PR provide.
Unlike the PR, this new code does honor the 'log count' in
newsyslog.conf so old logfiles are deleted. This new code does not
currently support never deleting the archived logfiles.
