Gather preconnection use vs waste statistics

I now gather statistics only in the transport socket
classes TcpClientSocket*.  All other socket classes
forward significant data (that they are used in
a speculation) to their transport class, where
this data is stored, and then dumped when the
TCP socket is closed.

This CL also repaired a slight miscount in bytes
read and written on Windows, as error codes
were mistakenly accumulated as byte counts.

This CL repaired a significant undercounting 
in linux/mac via StatsCounter (the logging counter
appears correct).

Libjingle support is minimal (NOTREACHED), but
I don't know that there are subresources that will
be speculatively preconnected from that class (and
it is less obvious how the class uses underlying
sockets, if at all).
