Add a new at_shutdown queue, SHUTDOWN_FINAL. This queue is run at
splhigh() after any system dumps have completed. SHUTDOWN_POST_SYNC
isn't quite late enough for disk controllers.
Converted at_shutdown queues to use the queue(3) macros.

This software was developed with the support of the Defense Advanced
Research Projects Agency (DARPA).
Updated the ch(4) driver and chio(1) command to include volume
tag support. These changes have been tested with a Breeze Hill
Q47 DLT and a DEC DLT2500 media changer. The latter has no
volume tag support.
The chio(1) command was updated to include various flags to the
status subcommand. These flags can be used to select additional
information to be displayed (like volume tags).
A new chio(1) subcommand named 'voltag' has been added which allows
for changes to volume tags inside the media changer controller.
This could not be tested as the Q47 does not provide the functio-
nality.
Massive overhaul of the aic7xxx driver:
- Convert to CAM
- Use a new DMA based queuing and paging scheme
- Add preliminary target mode support
- Add support for the aic789X chips
- Take advantage of external SRAM on more controllers.
- Numerous bug fixes and performance improvements.

RECEIVE/SEND processor target requests to the "targ" sample target mode
driver.

Add new functions fill_fpregs() and set_fpregs(), like fill_regs()
and set_regs() but for the floating point register state. The code
is stolen from procfs_machdep.c, and moved out of there into
machdep.c.
These functions are needed for generating ELF core dumps.

Add reallocf to the library. This function is simliar to realloc, but
when it returns NULL to indicate failure, it will also free the memory
that was passed to it, if that was non-null.
This does not change the semantics of realloc.
A second commit will be done to commit the conversion of those places in
the code that can safely use this to avoid memory leaks when confronted
with low memory situations.

Add generic defines ELF_ARCH, ELF_CLASS, and ELF_DATA. These give
the relevant characteristics of the native machine, for building
and checking Elf_Ehdr structures.
Add structures to represent ELF "note" headers. Add defines for the
note types used in ELF core files.

Resynch with working sources before BTX integration.
- Use format-independant module allocator.
- Conditionalise ISA PnP support.
- Simplify PnP enumerator interface.
- Improve module/object searching.
- Add missing depend/install targets in BTX makefiles.
- Pass the kernel environment and module data in extended bootinfo fields.
- Add a pointer to the end of the kernel + modules in bootinfo.
- Fix parsing of old-style kernel arguments.

This implements retrieving the contents of message buffer via sysctl(3)
as "machdep.msgbuf". It's needed in case of using stripped kernels, where
normal dmesg (which has to use kvm) doesn't work.
The buffer is unwound, meaning that the data will be linear, possibly
with some leading NULLs.

Support our "nfsv2" option. (originally added to old amd/amd/host_opts.c
rev 1.5)
The "nfsv2" option is equivant to "proto=udp,vers=2". It is debatable
whether NFS v2 should force "proto=udp" but I figure that is what most people
will expect. Note, I can get the new Amd to mount a 2.2-STABLE box with
"proto=tcp,vers=2". RFC 1094 does not disallow such behavior.

Add provisions for variant core dump file formats, depending on the
object format of the executable being dumped. This is the first
step toward producing ELF core dumps in the proper format. I will
commit the code to generate the ELF core dumps Real Soon Now. In
the meantime, ELF executables won't dump core at all. That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

Support PnP compatibility IDs. This allow e.g. the ed driver to pick
up any PnP NE2000 compatible card, instead of forcing us to always
update ID lists.
