jonathan 4ae1f36dc9 Commit TCP SACK patches from Kentaro A. Karahone's patch at: 
http://www.sigusr1.org/~kurahone/tcp-sack-netbsd-02152005.diff.gz

Fixes in that patch for pre-existing TCP pcb initializations were already
committed to NetBSD-current, so are not included in this commit.

The SACK patch has been observed to correctly negotiate and respond,
to SACKs in wide-area traffic.

There are two indepenently-observed, as-yet-unresolved anomalies:
First, seeing unexplained delays between in fast retransmission
(potentially explainable by an 0.2sec RTT between adjacent
ethernet/wifi NICs); and second, peculiar and unepxlained TCP
retransmits observed over an ath0 card.

After discussion with several interested developers, I'm committing
this now, as-is, for more eyes to use and look over.  Current hypothesis
is that the anomalies above may in fact be due to link/level (hardware,
driver, HAL, firmware) abberations in the test setup, affecting  both
Kentaro's  wired-Ethernet NIC and in my two (different) WiFi NICs.
