From: Eric leblond <eric@xxxxxx>
This patch adds new SQL schema for MySQL and PGsql. The goal is to improve the one
line per entry format. There is no more a big table with all fields because this
sort of storage is causing bad performance (databases don't like to have a lot of
NULL fields to store).
Main changes are :
* Add new schema for MySQL and PGsql
* Use call to configurable procedure in SQL OUTPUT modules
* Arguments of a procedure are given by the list of fields of a selected table

+-- general notes:
+-- - tables are split using the protocol
+-- - keys are created outside the table, when possible
+-- - foreign keys (constraints) are added using ULOG2_ADD_FOREIGN_KEYS()
+-- - some procedures for maintainance are provided (suppressing entries, compressing tables, running ~VACUUM)
+-- - security is set to INVOKER, which means the permissions of the connected client are used. To create an abstraction layer, DEFINER could be used (with precautions on DELETE ..)
+
+
+-- (most constraint) ulog2_ct >> tcp,udp,icmp >> ulog2 (least constraint)
