Remove many obsolete files. The majority of these are simply no
longer included as part of the OpenSSL distribution. However, a few
we just don't need and are explicitly excluded in FREEBSD-Xlist.
Add a quick check that device actually has sound capabilities. The problem
is that some cards built around fm801 chip have the same device ID, only
have radio tuner onboard, but no sound capabilities. Therefore, with such
card inserted and `device pcm' in kernel the user has a big problem, as
the fm801 driver effectively hangs the machine when trying to initialise
nonexistent ac97 codecs (it does 500 retries with 1 second interval!).
It would be better if MediaForte's engeneers were smart enough to put
different device ID into such cards, but it isn't an option.
Since pam_get_authtok(3) doesn't know about our options structure, setting
the PAM_ECHO_PASS option on-the-fly is a NOP (though it wasn't with the
old pam_get_pass(3) code). Instead, call pam_prompt(3) directly. This
actually simplifies the code a bit.

vm_page_sleep_busy() with vm_page_sleep_if_busy(). At the same time,

Add a bunch more cards that are known to work.
Add a warning about the Symbol LA-4100 series of cards. You gotta
load special firmware, and the wi driver in the tree doesn't support
that yet.
- Optimize wakeup() and its friends; if a thread waken up is being
swapped in, we do not have to ask for the scheduler thread to do
that.
- Assert that a process is not swapped out in runq functions and
swapout().
- Introduce thread_safetoswapout() for readability.
- In swapout_procs(), perform a test that may block (check of a
thread working on its vm map) first. This lets us call swapout()
with the sched_lock held, providing a better atomicity.
Add definitions for statistical and high-resolution profiling. The calling
conventions for _mcount and __cyg_profile_func_enter are different, so
statistical profiling kernels build and link but don't actually work.
IWBNI one could tell gcc to only generate calls to the former.
Define uintfptr_t properly for userland, but not for the kernel (I hope).
The data cache on UltraSPARC III is not directly mapped, so don't assert
that. This breaks assumptions made by some of the cache flushing code,
but UltraSPARC III has different methods for invalidating cache lines
anyway.
Create a new thread state to describe threads that would be ready to run
except for the fact tha they are presently swapped out. Also add a process
flag to indicate that the process has started the struggle to swap
back in. This will be needed for the case where multiple threads
start the swapin action top a collision. Also add code to stop
a process fropm being swapped out if one of the threads in this
process is actually off running on another CPU.. that might hurt...

Create a new header <machine/_stdint.h> for storing MD parts of
<stdint.h>. Previously, parts were defined in <machine/ansi.h> and
<machine/limits.h>. This resulted in two problems:
(1) Defining macros in <machine/ansi.h> gets in the way of that
header only defining types.
(2) Defining C99 limits in <machine/limits.h> adds pollution to
<limits.h>.

If we are in hostap mode, do not go into promisc mode. This causes
problems with the firmware and will result in a) poor performance and
b) the inability to associate certain types of cards (most notibly

Revert rev 1.131.
1.131 is slightly broken, and I would commit the fix to that here, but it
has been reported that any deviation from the original code is causing
problems with some 82557 chips, causing them to lock hard.
Until those issues have been figured out, going back to the original

Make a temporary copy of the output data in the generic sysctl handlers
so that the data is less likely to be inconsistent if SYSCTL_OUT() blocks.
If the data is large, wire the output buffer instead.
This is somewhat less than optimal, since the handler could skip the copy
if it knew that the data was static.
If the data is dynamic, we are still not guaranteed to get a consistent
copy since another processor could change the data while the copy is in
progress because the data is not locked. This problem could be solved if
the generic handlers had the ability to grab the proper lock before the
copy and release it afterwards.
This may duplicate work done in other sysctl handlers in the kernel which
also copy the data, possibly while a lock is held, before calling they call
a generic handler to output the data. These handlers should probably call
SYSCTL_OUT() directly.

Wire the sysctl output buffer before grabbing any locks to prevent
SYSCTL_OUT() from blocking while locks are held. This should
only be done when it would be inconvenient to make a temporary copy of
the data and defer calling SYSCTL_OUT() until after the locks are
released.
Fix a bug introduced in previous commit. Due to the interaction of the
direct physical mappings with virtual page colour, we need to flush the
data cache when a page changes colour. I missed one case which broke

Revert the previous delta; uintfptr_t needs to be available to
userland for libc/gmon to compile, so the typedef in <machine/types.h>
