Alter the way PINGs for /sping and lag check are used.

Browse Source 
We now send PING <server> :<server> for /spings, and
PING LAG!<cookie>.<tv_sec>.<tv_usec> :<server> for lag checks.  The cookie is
set randomly at server connect time, and means that clients connected to the
same bouncer shouldn't act on each other's lag checks.

We can now remove in_sping entirely - previously it would get out of synch if
you disconnected with a sping in progress.
