Try to fix problem if balancing free client DCB and free session so that auth data is always available and client DCB is not freed until session is ready to be freed. Also fix problem in auth logic.

Changes to improve robustness of SSL processing, separate it so far as possible from protocols. Separate the detailed mechanism of authentication from the MySQL protocol with a view to making it into a module later.

971d1d5de2
Redesign logic of SSL connections to work with status in client DCB instead of in the protocol. This eases the way to moving SSL logic out of a specific protocol (currently MySQL) so as to be available across any protocol. Also, some simplification.

8367d93746
Migrate SSL functionality out of service and into listener. Develop config handling accordingly, including making provision for SSL parameters in servers for future use in implementing SSL to backend servers. Some elements still to be tidied mainly in mysql_client.c - but that will be part of detaching the SSL authentication from the MySQL protocol.

Unify DCB close processing to single function dcb_close. Remove dcb_add_to_zombieslist (incorporating logic into dcb_close). Alter logic so that DCB that is just allocated will still go to zombie list if dcb->fd is not closed.

session.c:session_free:if session is child of another service (tee in this case), it is the parent which releases child's allocated memory back to the system. This now also includes the child router session.
dcb.h: Added DCB_IS_CLONE macro
tee.c:freeSession:if parent session triggered closing of tee, then child session may not be closed yet. In that case free the child session first and only then free child router session and release child session's memory back to system.
tee.c:routeQuery: only route if child session is ready for routing. Log if session is not ready for routing and set tee session inactive
mysql_client.c:gw_client_close:if DCB is cloned one don't close the protocol because they it is shared with the original DCB.

...
tee.c:closeSession removed unnecessary dcb_free, router/service closes all backend DCBs and the client DCB, and client DCB is the one that was tried to free in closeSession.
readwritesplit.c:routeQuery now handles untyped and typed GWBUFs. Untyped means that read buffer may consist of incomplete and multiple MySQL packets. Typed buffer always consists of a single MySQL packet (which can be split to many buffers inside GWBUF).
Fixed Coverity cases #84840 and #84841

Session-specific logging. Added functions
...
void session_enable_log(SESSION* ses, logfile_id_t id)
and
void session_disable_log(SESSION* ses, logfile_id_t id)
Which switch specific log type on/off if the log type in question is not generally enabled.
Each thread carries a thread-specific struct log_info_t which includes members for current session id and bitfield for enabled log types for the current session. That information is checked before actual log write functions are called.
Each file where session-specific logging is used, must include the following exports:
/** Defined in log_manager.cc */
extern int lm_enabled_logfiles_bitmask;
extern size_t log_ses_count[];
extern __thread log_info_t tls_log_info;
