From RFC 793 s3.9 p58 Event Processing:
If RECEIVE Call arrives in CLOSED state and the user has access to such a
connection, the return should be "error: connection does not exist"
Fixes#1598
PiperOrigin-RevId: 293494287
All inbound segments for connections in ESTABLISHED state are delivered to the
endpoint's queue but for every segment delivered we also queue the endpoint for
processing to a selected processor. This ensures that when there are a large
number of connections in ESTABLISHED state the inbound packets are all handled
by a small number of goroutines and significantly reduces the amount of work the
goscheduler has to perform.
We let connections in other states follow the current path where the
endpoint's goroutine directly handles the segments.
Updates #231

The implementation follows the linux behavior where specifying
a TCP_USER_TIMEOUT will cause the resend timer to honor the
user specified timeout rather than the default rto based timeout.
Further it alters when connections are timedout due to keepalive
failures. It does not alter the behavior of when keepalives are
sent. This is as per the linux behavior.

Set the snd/rcv buffer sizes so that the test is deterministic and runs in a
reasonable amount of time. It also ensures that we disable any auto-tuning of
the send/receive buffer which may happen.

Ioctl was returning just the buffer size from epsocket.endpoint
and it was not considering data from epsocket.SocketOperations
that was read from the endpoint, but not yet sent to the caller.

This fixes a bug introduced in cl/251934850 that caused
connect-accept-close-connect races to result in the second connect call
failiing when it should have succeeded.

Adds support to set/get the TCP_MAXSEG value but does not
really change the segment sizes emitted by netstack or
alter the MSS advertised by the endpoint. This is currently
being added only to unblock iperf3 on gVisor. Plumbing
this correctly requires a bit more work which will come
in separate CLs.

This CL also cleans up the error returned for setting congestion
control which was incorrectly returning EINVAL instead of ENOENT.
