395cbdc103 Simplify handling of "client data" by having a pointer to it only in DCB and not in session structure. Change name of session->client to session->client_dcb for greater clarity. Temporary free of client data in DCB, to be moved to authenticator when it becomes a module. Fix incorrect name of listener_alloc. 2016-02-23 11:13:21 +00:00

ec281849aa Remove explicit calls to parse_query. 
Now that all query classifier functions parse the query if it
has not been parsed, there is no reason for any module to call
parse_query explicitly.

a8535f42af Remove all traces of logfile_t 
The earlier log file based approach for enabling and disabling
messages has now been completely replaced with the syslog priority
based approach.

Similarly as with log files before it is now possible to enable
and disable a log priority for a particular session, even though
it apparently has not been used much.

The local test-programs of the logging has got minimal attention
only to make them compile. They should get an overhaul as they did
not work before either.
