Use ACPI_SUCCESS/ACPI_FAILURE consistently.
The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER.
Add AcpiBatteryIsPresent helper to determine whether a battery device
is inserted.
Add ACPI_ALL_DRIVERS to the list of debug layers, now that we own the
namespace for this.

watchpoint support for debugging (under LOADER_DEBUG). Claim the
physical and virtual addresses used to map the kernel from the prom;
we map it ourselves behind the scenes though. Add a reboot command.

While in userland, keep the thread's ucred reference in a shadow
field so that the usual place to store it is NULL.
If DIAGNOSTIC is not set, the thread ucred is kept valid until the next
kernel entry, at which time it is checked against the process cred
and possibly corrected. Produces a BIG speedup in
kernels with INVARIANTS set. (A previous commit corrected it
for the non INVARIANTS case already)

Remove bowrite(), it is now unused.
This is the first step in getting entirely rid of BIO_ORDERED which is
a generally accepted evil thing.

so that this is safe even if VARIABLE is longer than kern.argmax.
There is another instance of CFILES which might need the same treatment,
and might be noticed when doing a "make links".
The same has to be done in RELENG_4 (on some different file).

counter type, as threatened in rev.1.8 (the density doesn't need to
be recorded since it can be derived from other fields). This doesn't
affect binary compatibility, but new utilities won't be able to depend
on the contents of this field because libc/gmon/gmon.c was broken --
it wrote garbage to the spare fields.
Added a history counter type field to struct gmonparam. This breaks
binary compatibility a little, since kgmon wanted to read the whole
struct. Fixed kgmon to only depend on reading the critical earlier
parts of the struct. This should also fix 6+ year old breakage of
binary compatibility when the profrate field was added.
Only initialize the new field in struct gmon for now, so that the
compatibility code for this (in kgmon) gets tested. The compatibility
code has to guesstimate the value. The new field in struct gmonparam
is for the kernel to initialize so that kgmon doesn't have to guess.
- P_INMEM checks in all the functions. P_INMEM must be checked because
PHOLD() is broken. The old bits had bogus locking (using sched_lock)
to lock P_INMEM. After removing the P_INMEM checks, we were left with
just the bogus locking.
- large comments. They were too large, but better than nothing.
Remove obfuscations that were gained in transition in rev.1.76:
- PROC_REG_ACTION() is even more of an obfuscation than PROC_ACTION().
The change copies procfs_machdep.c rev.1.22 of i386/procfs_machdep.c
verbatim except for "fixing" the old-style function headers and adjusting
function names and comments. It doesn't remove the bogus locking.

OUT status. We are, apparently, required to force the f/w to log back in
if we want to try and talk to that disk again. This means either issuing
a LOGIN LOCAL LOOP PORT mailbox command, or by issuing a LIP. I've elected
to issue a LIP because this has a better chance of waking up the disk which
clearly just crashed and burned.
These should not occur at all. If they do, they should be darned rare.

It doesn't actually do it yet though. This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on. make -DNO_WERROR would also bypass all of it.
so that after the first time we can follow the pointer instead
of having to scan the list.
This was the intended behaviour from day one.
