New TCP reassembly code. The new code reduces the memory needed by

out-of-order packets and builds the infrastructure needed for sending
SACK blocks (to be added shortly).

Fix to ensure that the correct MSS is advertised for loopback
...
TCP connections by using the MTU of the interface. Also added
a knob, mss_ifmtu, to force all connections to use the MTU of
the interface to calculate the advertised MSS.

From 4.4BSD-Lite2 (noted by Frank van der Linden):
...
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time. However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere). Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

Implement an infrastructure to allow larger initial congestion windows.
...
The sysctl'able variable "tcp_init_win", when set to 0, selects an
auto-tuning algorithm for selecting the initial window, based on transmit
segment size, per discussion in the IETF tcpimpl working group.
Default initial window is still 1 segment, but will soon become 2 segments,
per discussion in tcpimpl.

In the PRU_RCVD entry point, if TF_DELACK is set, don't send the window
...
update now, since it will be sent within 200ms when the delayed ACK is
sent. Instrument how many hits we get on this optimization.
