rS289879: newsyslog.conf: allow to configure the signal using the signal name.
Summary

Before this patch, signals in newsyslog.conf must be configured using the number (e.g. 30 for SIGUSR1). This patch add the possibility to write the signal name (e.g. SIGUSR1) and adapt the man page accordingly.

signame_to_signum taken from kill(1), manpage changes based on OpenBSD's newsyslog.conf.

I think the whole logic of validating signal should reuse something like https://svnweb.freebsd.org/base/head/usr.bin/timeout/timeout.c?view=markup&pathrev=278810#l103
It would simplify lots of things

Here is a sample test session using the -v (verbose) and -n (don't trim but print actions) options.

At first, we have a simple test config using a signal number (and also an executable path to test compatibility) and see the result with /usr/sbin/newsyslog (testing on 10.2-RELEASE-p5). Then we include a rotation using the signal name and run the patched newsyslog command. As a result it seems to interpret correctly both the signum and shellcmd lines (as the non-patched version does), while successfully parsing and executing the signame line.
