REGRESSION is enabled, allows user space to dictate that sonewconn()

Kernel changes:
Inform hwpmc of executable objects brought into the system by
kldload() and mmap(), and of their removal by kldunload() and
munmap(). A helper function linker_hwpmc_list_objects() has been
added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve
the list of currently loaded kernel modules.
The unused `MAPPINGCHANGE' event has been deprecated in favour
of separate `MAP_IN' and `MAP_OUT' events; this change reduces
space wastage in the log.
Bump the hwpmc's ABI version to "2.0.00". Teach hwpmc(4) to
handle the map change callbacks.
Change the default per-cpu sample buffer size to hold
32 samples (up from 16).
Increment __FreeBSD_version.
libpmc(3) changes:
Update libpmc(3) to deal with the new events in the log file; bring
the pmclog(3) manual page in sync with the code.
pmcstat(8) changes:
Introduce new options to pmcstat(8): "-r" (root fs path), "-M"
(mapfile name), "-q"/"-v" (verbosity control). Option "-k" now
takes a kernel directory as its argument but will also work with
the older invocation syntax.
Rework string handling in pmcstat(8) to use an opaque type for
interned strings. Clean up ELF parsing code and add support for
tracking dynamic object mappings reported by a v2.0.00 hwpmc(4).
Report statistics at the end of a log conversion run depending

reason, seems to be where new flags are getting defined:
INP_DROPPED - The protocol has terminated this connection and the socket
is not reusable: when the socket code enters the protocol,
an error is immediately returned. This will substitute for
NULLing the so_pcb socket field, helping to implement the
invariant that all valid sockets have valid pcb's in TCP.
INP_SOCKREF - The protocol has become the owner of the socket reference,
and will need to free it when freeing the pcb, which will
be used when a TCP socket is closed but still has queued
data.

the error on sparc64 hadn't changed since the last checkin, pass
LINT on other platforms and mpt doesn't work on sparc64 anyway
and the tinderbox build didn't work for me in a cross build case
on my main build machine (which runs RELENG_6). Sigh. Still
need to try harder.
- Introduce invariant that all IPX/SPX sockets will have valid so_pcb
pointers to ipxpcb structures, and that for SPX, the control block
pointer will always be valid. Don't attempt to free the socket or
pcb at various odd points, such as disconnect.
- Add a new ipxpcb flag, IPXP_DROPPED, which will be set in place of
freeing PCB's so that this invariant can be maintained. This flag
is now checked instead of a NULL check in various socket protocol
calls.
- Introduce many assertions that this invariant holds.
- Various pieces of code, such as the SPX timer code, no longer needs
to jump through hoops in case it frees a PCB while running.
- Break out ipx_pcbfree() from ipx_pcbdetach(). Likewise
spx_pcbdetach().
- Comment on some SMP-related limitations to the SPX code.
- Update copyrights.

A) Fibre Channel Target Mode support mostly works
(SAS/SPI won't be too far behind). I'd say that
this probably works just about as well as isp(4)
does right now. Still, it and isp(4) and the whole
target mode stack need a bit of tightening.
B) The startup sequence has been changed so that
after all attaches are done, a set of enable functions
are called. The idea here is that the attaches do
whatever needs to be done *prior* to a port being
enabled and the enables do what need to be done for
enabling stuff for a port after it's been enabled.
This means that we also have events handled by their
proper handlers as we start up.
C) Conditional code that means that this driver goes
back all the way to RELENG_4 in terms of support.
D) Quite a lot of little nitty bug fixes- some discovered
by doing RELENG_4 support. We've been living under Giant
*waaaayyyyy* too long and it's made some of us (me) sloppy.
E) Some shutdown hook stuff that makes sure we don't blow
up during a reboot (like by the arrival of a new command
from an initiator).
There's been some testing and LINT checking, but not as
