Log Message:

  src/sys/netinet/tcp_subr.c    1.225
(requested by cube in ticket #1109).

- Make sure we send a reasonable fragment size when IPSEC is configured.
  Otherwise we end up sending a dubious "0" whenever we cannot find a
  proper association for the packet.
- Reset sack_newdata along with snd_nxt to avoid improper integer
  arithmetics that lead to sending data from an incorrect place in the
  stream, making it appear as corrupted.

Patch by Michael Van Elst, based on an analysis by Michael for the IPSEC
stuff and I for the SACK issue.
