This commit makes the following changes:
- Keep track of the time of the last read in the transport.
- Use this in the keepalive implementation to decide when to send out
keepalives.
- Address the issue of keepalives being sent every [Time+Timeout] period
instead of every [Time] period, as mandated by proposal A8.
Proposal A8 is here:
