Fix PAWS (Protect Against Wrapped Sequence numbers) in cases when hz >> 1000 and thus getting outside the timestamp clock frequenceny of 1ms < x < 1s per tick as mandated by RFC1323, leading to connection resets on idle connections.
Always use a granularity of 1ms using getmicrouptime() making all but relevant callouts independent of hz.
Use getmicrouptime(), not getmicrotime() as the latter may make a jump possibly breaking TCP nfsroot mounts having our timestamps move forward for more than 24.8 days in a second without having been idle for that long.

- Tighten up the Timestamp checks to prevent a spoofed segment from setting ts_recent to an arbitrary value, stopping further communication between the two hosts. - If the Echoed Timestamp is greater than the current time, fall back to the non RFC 1323 RTT calculation.

Remove RFC1644 T/TCP support from the TCP side of the network stack.
A complete rationale and discussion is given in this message and the resulting discussion:
http://docs.freebsd.org/cgi/mid.cgi?4177C8AD.6060706
Note that this commit removes only the functional part of T/TCP from the tcp_* related functions in the kernel. Other features introduced with RFC1644 are left intact (socket layer changes, sendmsg(2) on connection oriented protocols) and are meant to be reused by a simpler and less intrusive reimplemention of the previous T/TCP functionality.

Add support for TCP Selective Acknowledgements. The work for this originated on RELENG_4 and was ported to -CURRENT.
The scoreboarding code was obtained from OpenBSD, and many of the remaining changes were inspired by OpenBSD, but not taken directly from there.
You can enable/disable sack using net.inet.tcp.do_sack. You can also limit the number of sack holes that all senders can have in the scoreboard with net.inet.tcp.sackhole_limit.

Much delayed but now present: RFC 1948 style sequence numbers
In order to ensure security and functionality, RFC 1948 style initial sequence number generation has been implemented. Barring any major crypographic breakthroughs, this algorithm should be unbreakable. In addition, the problems with TIME_WAIT recycling which affect our currently used algorithm are not present.

Temporary feature: Runtime tuneable tcp initial sequence number generation scheme. Users may now select between the currently used OpenBSD algorithm and the older random positive increment method.
While the OpenBSD algorithm is more secure, it also breaks TIME_WAIT handling; this is causing trouble for an increasing number of folks.
To switch between generation schemes, one sets the sysctl net.inet.tcp.tcp_seq_genscheme. 0 = random positive increments, 1 = the OpenBSD algorithm. 1 is still the default.
Once a secure _and_ compatible algorithm is implemented, this sysctl will be removed.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Restructure TCP timeout handling:
- eliminate the fast/slow timeout lists for TCP and instead use a callout entry for each timer. - increase the TCP timer granularity to HZ - implement "bad retransmit" recovery, as presented in "On Estimating End-to-End Network Path Properties", by Allman and Paxson.
