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.

dcb_close sets some session fields to NULL:

dcb->session->client = NULL;

There is a local copy of dcb->seesion before setting it to NULL

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.

Added simple_mutex_t dcb->mutex to DCB struct to protect processing of single dcb in poll.c:poll_waitevents. This is a coarse locking but seems to work with multiple threads at least with very simple load.
