We have been unnecessarily creating too many savable types implicitly.

This CL also puts the congestion control logic behind an
interface so that we can easily swap it out for say CUBIC
in the future.

There is a subtle bug where during cleanup with unread data a FIN can
be converted to a RST, at that point the entire connection should be
aborted as we're not expecting any ACKs to the RST.

So that when saving TCP endpoint in these states, there is no pending or
background activities.
Also lift tcp network save rejection error to tcpip package.

is specified, which is equivalent to POLLHUP | POLLERR which are
implicitly added during the poll syscall.

Today when we transmit a RST it's happening during the time-wait
flow. Because a FIN is allowed to advance the acceptable ACK window
we're incorrectly doing that for a RST.

Previously, dual stack UDP sockets bound to an IPv4 address could not use
sendto to communicate with IPv4 addresses. Further, dual stack UDP sockets
bound to an IPv6 address could use sendto to communicate with IPv4 addresses.
Neither of these behaviors are consistent with Linux.
