 * History
 * -------
 *
 * 2003-01-23: switched from t_uac to t_uac_dlg (dcm)
 * 2003-02-28: protocolization of t_uac_dlg completed (jiri)
 * 2003-03-11: updated to the new module interface (andrei)
 *             removed non-constant initializers to some strs (andrei)
 * 2003-03-16: flags parameter added (janakj)
 * 2003-04-05: default_uri #define used (jiri)
 * 2003-04-06: db_init removed from mod_init, will be called from child_init
 *             now (janakj)
 * 2003-04-07: m_dump takes a parameter which sets the way the outgoing URI
 *             is computed (dcm)
 * 2003-08-05 adapted to the new parse_content_type_hdr function (bogdan)
 * 2004-06-07 updated to the new DB api (andrei)
 * 2006-09-10 m_dump now checks if registering UA supports MESSAGE method (jh)
 * 2006-10-05 added max_messages module variable (jh)
 * 2011-10-19 added storage of extra SIP headers (hpw)
 * 2011-12-07 added storage of extra SIP headers from AVP (jh)
