ptrace_set_pc(), and cpu_ptrace() so that those functions are free to
acquire Giant, sleep, etc. We already do a PHOLD/PRELE around them so
that it is safe to sleep inside of these routines if necessary. This
allows ptrace() to be marked MP safe again as it no longer triggers lock
order reversals on Alpha.

snprintf() and vsnprintf() in FreeBSD kernel land).
This is needed by the Intel Centrino 2200BG driver. Unfortunately, this
driver still doesn't work right with Project Evil even with this tweak,
but I'm unable to diagnose the problem since I don't have access to a
sample card.
- Add <sys/param.h> and <limits.h> where required (do not depend on other
headers pulling it in).
- __dead -> __dead2
- #if defined() -> #ifdef
- Remove ugly PRIu64 macros and use %llu w/ (unsigned long long) cast.
All changes looped back to OpenBSD (where applicable) for easier sync in the
future.

This adds support for cardbus ATA/SATA controllers. I get roughly the
same transfer speeds as on true PCI controllers. Nice to be able to add
a couble of "real" disks to a laptop :)
add tapmtx, which protects globale variables.
Notes:
- The EBUSY check in MOD_UNLOAD may be subject to a race. Moving the
event handler unregister inside the mutex grab may prevent that race.
- Locking of global variables safely is now possible because tapclones
is only modified when the module is loading or unloading, thanks to
phk's recent chang to clone_setup().
- softc locking to follow.
255; USB keychains exist that use 256 as the number of heads. This
check has also been removed in Darwin (along with most of the other
head/sector sanity checks).
Only cy, bs and wd in the tree still use it. I have a replacement for
cy that I need to test on ISA and PCI cards. bs and wd are pc98 only
drivers that appear to no longer be necessary. I'll be removing them
when I hear back from the pc98 people.
rdp(4), le(4), stl(4), stli(4), ctx(4), spigot(4).
Take a guess that the following devices correspond to removed drivers
and blow their entries away too: "Genius and Mustek hand scanners"
(gsc(4)?) and "GPB and Transputer drivers" (gpib(4)?).
this driver is being retired. Remove it from the tree. If someone
wants to update it to the latest APIs and can test the hardware, it
can return to the tree.
