Use the standard syslog levels on CARP logging messages instead of

simple on/off, allowing more control over how verbose the logging is.
This also allows you to do a further level of filtering in syslog.conf
if you need to.

Also add logging of state changes, inspired by diff provided by
Brian A. Seklecki in PR 5513. These messages are logged by default.
