log: provide missing macros
With commit d094a0734cee ("log: allow for message continuation") we have
defined a special log level and category for message continuation. Let's
have a macro for using these.
If logging is enabled log_cont() will create a continuation log output with
the same logging level and category as the previous message.
If logging is not enabled, log_cont() will print like printf().
Provide macros for logging levels LOG_EMERG, LOG_ALERT, LOG_CRIT.
