MXS-421 Allow specifying a facility when logging

Browse Source 
In principle a syslog priority consists of a syslog level
bit-or:d with a syslog facility. That's clear from the syslog
man page, but not so clear from the code in syslog.h.

Anyway, to make it possible to log using a specific facility
(instead of the default LOG_USER), we must allow priorities
that include a specified facility.
