Previously, it used atoi(3) to parse the unit parameter, which would silently
yield a unit of 0 in the presence of an invalid unit number.  As most users of
mpsutil(8) are likely to have at least a unit 0, this is could have confusing
results.

This behaviour was particularly unintuitive if one incorrectly passed an
adapter device name, or a device path, instead of a unit number.  In addition
to using strtoumax(3) instead of atoi(3) to parse unit numbers, support
stripping a device name (e.g. mps1) or path (e.g. /dev/mps2) to just its unit
number.

Currently newsyslog supports <include> directive that is used
in our default /etc/newsyslog.conf in the following form:

<include> /usr/local/etc/newsyslog.conf.d/*

While this is suitable for ports installing their own rules
for logs rotation, this also makes newsyslog break entire
processing of all files if it encounters single line it cannot parse.
This includes lines referring to nonexistent username/group for log
ownership, so newsyslog stops calling errx() function in the parser.

With this fix, newsyslog uses warnx() instead of errx() in such cases
to print a warning, recover gracefully and continue with execution.

Among other cases, this unbreaks initial creation of log files
having flag "C" at boot time (newsyslog -CN). This is most important
for systems having RAM-based /var file system like nanobsd(8)-based
that rely on newsyslog to bring system log files into existence.
