Add net log entries that summarize transmit and receive byte counts.

Tx/Rx summaries are integrated into the net log at the last point that bytes were transmitted or received.

Hopefully this will help resolve http://crbug.com/37729 by showing if we've received bytes over the network when we hit the "Waiting for cache" bug.

This change also modernizes the use of NetLog:
 - ClientSocket now has a net_log() accessor
 - ClientSocket::Connect no longer takes a NetLog, instead the TCPClientSocket constructor takes one, others use their transport socket's NetLog
 - TCPClientSocket creates a new source id with source type SOCKET

Also updates PassiveLogCollector infrastructure:
 - The LiveRequestsObserver lets a RequestTracker update a RequestInfo just before it is displayed.  This allows ConnectJobs to be associated with URLRequests while connecting and then reassociated if they are late-bound to a different request.
