Log Message:
Pull up revision 1.63 (requested by jonathan in ticket #405):
Rework to make  FAST_IPSEC PF_KEY dumps unicast and reliable:
Introduce new socket-layer function sbappendaddrchain() to
sys/kern/uipc_socket2.c: like sbappendaddr(), only takes a chain of
records and appends the entire chain in one pass. sbappendaddrchain()
also takes an `sbprio' argument, which indicates the caller requires
special `reliable' handling of the socket-buffer.  `sbprio' is
described in sys/sys/socketvar.h, although (for now) the different
levels are not yet implemented.
Rework sys/netipsec/key.c PF_KEY DUMP responses to build a chain of
mbuf records, one record per dump response. Unicast the entire chain
to the requestor, with all-or-none semantics.
Changed files;
        sys/socketvar.h kern/uipc_socket2.c netipsec/key.c
Reviewed by:
        Jason Thorpe, Thor Lancelot Simon, post to tech-kern.
Todo: request pullup to 2.0 branch.  Post-2.0, rework sysctl() API for
dumps to use new record-chain constructors. Actually implement
the distinct service levels in sbappendaddrchain() so we can use them
to make PF_KEY ACQUIRE messages more reliable.
