Add package variable $DBQUERY_MAXTRIES, to control query retry in the
case that the mysql server goes away suddenly. Defaults to 1, which gives us the behaviour we have now. Used like this after loading libdb: $libdb::DBQUERY_MAXTRIES = 5; The query will be retried this many times. For infinite retry, set it to zero! Note that I'm not entirely sure if queries are atomic, so beware if you use this. Also some minor cleanup of $scriptname usage, some of which was duplicated in the connect routine.
