session was assigned state SESSION_STATE_READY outside protected block, and backend dcb thread saw authentication data and session in SESSION_STATE_ALLOC state, which trapped. Moved state assignment inside protection block.

Added spinlock protection for the session association to the DCB and
...
reworked the reference count mechanism on the session. Introduced a
FREE state for the session and alter the session destruction flow so
that we only remove the session when all the DCB's have singled they
have finished processing events for the DCB rather than when the first
thread decides to clsoe the DCB.

Added spinlock ses_lock to struct SESSION to ensure that for each session closeSession is called only once.
...
closeSession is called from mysql_backend.c:gw_read_backend_event, and from dcb.c:dcb_close.
This is part of Bug #163 .
