Fixes symtoms described in http://bugs.skysql.com/show_bug.cgi?id=454
...
Added DCB state check to backend error evend handler. If state isn't DCB_STATE_POLLING anymore, socket is closed with purpose or error occurred but it has already been handled.
Client doesn't hang anymore at least with the documented method.

Moved error messages about broken pipe to DEBUG build since in cases we've seen it is due to socket closing in same host. Other case is that MaxScale attempts to write COM_QUIT (ending message) to socket that other thread already closed.
...
Added counter clean-up code to readwritesplit closeSession. If operation counters have leaked, that is, due to some error in query routing some counter have been left positive, it is zeroed at session ending. This ensures that there is no garbage in global counter even if individual session wouldn't clean up its counters.

Fixed bug in session command resul handling. In case where backend sent error message the session command cursor wasn't updated properly.
Added check to bref_clear_state, if bref's waiter counter would go negative, decrement to global operation counter is skipped.

Added status bit BREF_QUERY_ACTIVE to indicate if a query, other than session command, sent to backend for execution. The flag is cleared when the first packet belonging to the response arrives.
...
The flag is part of the active operation counting, which is utilized in load balancing. The active operation count per backend is used by default as criteria when router chooses to which backend a query should be routed.

Setting and clearing BREF_WAITING_RESULT also includes atomic increment and decrement of corresponding backend server's current operations counter, backend_server->stats.n_current_ops.
