Srivats P 5ec7010c51 Fix contention for port streamStats across threads
Tx/Rx stream stats related threads no longer have a direct reference to the
port's stream stats - instead they have their own copy that they keep and
return (in a reset-on-read fashion) when asked for. Each copy also has it's
own lock to prevent contention for read/update/clear.

PcapPort now fetches Tx(Transmitter) and Rx(Poller) stats on demand and
updates the port's stream stats - under protection of a lock.
