ubik: log important messages at default log level
Many important ubik messages (e.g., errors, warnings, sync state
changes) are logged at log level 5 (-d 5) or higher. Many sites are
reluctant to run ubik servers at a logging level higher than the default
due to the large number of extremely noisy informational messages at log
level 5. Therefore, many important log messages are never seen.
Instead, issue critical errors, warnings, and other important messages
at log level 0 so that they are always seen, even at the default logging
level.
In addition, disambiguate the two "I am no longer sync-site" messages by
adding a unique reason text to each.
