. memory corruption fix in stats/threading.
. fix for the excessive page flush bug leading to higher bandwidth than expected
with vorbis streams from certain source clients.
. avoid the ::ffff: part from IPv6 within an IP.

The other main change is the YP thread which is started from a dummy client
handle instead of the slave thread. it should now only startup from the worker
if there is work scheduled. Whether the slave thread can reduce wakeups would
need to be investigated.

command auth was updated but the performance results are similar to URL auth.
Other some internal code cleanups are also done. stats seems to be working much
better now.
