In case this causes trouble for some other chipsets add a comment how to
proceed. If we don't get bugreports, this should be removed after a while
(some releases?).

Apologies to everyone who has run portsnap in 7.0-CURRENT since
Tuesday; if there is a file "/.portsnap.INDEX" on your system, you can
delete it (or even better, move it to /usr/ports/.portsnap.INDEX).

believe that there are PC98 systems with an OPTi chip.
I don't know enough about this special PC architecture to be sure about
this, so let's find out by letting people with such a system complain in
case this commit breaks the sound system for them. It's easy to revert
then.

same as today: do no power management. 1 means be conservative about
what you power down (any device class that has caused problems gets
added here). 2 means be agressive about what gets powered down (any
device class that's fundamental to the system is here). 3 means power
them all down, reguardless. The default is 1.
The effect in the default system is to add mass storage devices to the
list that we don't power down. From all the pciconf -l lists that
I've seen for the aac and amr issue, the bad device has been a mass
storage device class.
This is an attempt at a compromise between the very small number of
systems that have extreme issues with powerdown, and the very large
number of systems that gain real benefits from powerdown (I get about
20% more battery life when I attach a minimal set of drivers on my
Sony). Hopefully it will strike the proper balance.

(wchar_t is defined in stddef.h, and only two files need more than that.)
Portability: Since the wchar requirements are really quite modest,
it's easy to define basic replacements for wcslen, wcscmp, wcscpy,
etc, for use on systems that lack <wchar.h>. In particular, this allows
libarchive to be used on older OpenBSD systems.
The OpenFirmware console isn't used on real systems anymore and
I never get to multi-user mode in psim. There are problems with
zs that need to be resolved before these lines can be enabled.
This eliminates disconcerting warnings on boot.

list of frame sniffers so that trapframes can be detected. The kluge
is needed because this version of gdb only supports appending a
sniffer to the list of sniffers and the moment kgdb gets a chance to
add its own frame sniffer, the target's default frame sniffer is
already in the list. Since the default frame sniffer claims any
frame thrown at it, kgdb's frame sniffer never gets to smell (a
process much akin to tasting, but with lesser chance of hurling :-)
This commit adds dummy frame sniffers that never claim a frame and
as such don't fix anything yet. However, we now have frame sniffers
and they are being called, so it's just a matter of adding meat to
the bones and we'll be able to properly unwind across trapframes.

* New definition CHN_F_HAS_VCHAN.
- channel.c
* Use CHN_F_HAS_VCHAN to mark channel with vchan capability instead
of relying on SLIST_EMPTY(&channel->children) == true for better
clarification and future possible usages of children (like
'slave' channel).
* Various fixes, including blocksize / format bps allignment,
better 24bit seeking (mplayer, others).
* Improve format chain building, it's now possible to record something
to a format non-native to the soundcard through various feeder format
converters or to higher sampling rate. This also gains another feature,
like doing vchan mixing on non s16le soundcard such as sb8.
- sound.c
* Increase robustness within various function that handle vchan
creation / termination (these function need a total rewrite, but
that would cause other major rewrite within various places too!).
As far as its robustness can be guaranteed, leave it as is.
* Optimize channel ordering, prefer *real* hardware playback
channels over virtual channels. cat /dev/sndstat should look
better.
* Increase sndstat verbosity to include bufsoft/bufhard allocation.
- vchan.c
* Fix LOR 119.
- http://sources.zabbadoz.net/freebsd/lor.html#119
* Reorder / increase robustness of vchan_create() / destroy().
Enforce destroy_dev() during destroy operation, fix possible
panic / dangling character device.
- http://lists.freebsd.org/pipermail/freebsd-current/2005-May/050308.html
* Tolerate a little bit more during mixing process, this should help
non s16le soundcards.
Note: Recoring in a non-native rate/format may result in overruns. A friendly
application is wavrec from audio/wavplay. The problem is under
investigation.
