o Use 8 space hard tabs
o Eliminate trailing white space (while I'm here, just in a couple of places)
o wrap mostly at 80 columns (printf literal strings being the notable
exception)
o use return (foo) consistantly
o use 0 vs NULL more consistantly
o use queue(3) xxx_FOREACH macros where appropriate (some places used it
before, others didn't).
o use BSD line continuation parameters
Pendants will likely notice minor style(9) violations, but for the
most part the file now looks much much closer to style(9) and is
mostly self-consistant.

specific snd_mixer device rather than global across all mixers.
- Add per-mixer mute status and saved mute_level so that the mixer_hwmute()
function can now toggle the mute state when the mute button is pressed.
- Create a dynamic sysctl tree hw.snd.pcmX when a pcm device is registered.
- Move the hw.snd.hwvol_* sysctl's to hw.snd.pcmX.hwvol_* so that they
are now properly device-specific. Eventually when the mixers become
their own devices these sysctl's will move to live under a mixerX tree.
- Change the interface of the hwvol_mixer sysctl so that it reports the
name of the current mixer device instead of the number and is settable
with the name instead of the number.
- Add a new function mixer_hwinit() used to setup the dynamic sysctl's
needed for the hwvol support that can be called by drivers that support
hwvol.

to the SYSCTL_ADD_FOO() macros is a constant that should be turned into
a string via the pre-processor. Instead, require it to be an explicit
string so that names can be generated on the fly.
- Make some of the char * arguments to sysctl_add_oid() const to quiet
warnings.
'chancount' never got up to equaling 'maxchans'. As a result,
pcm_makelinks() was never called, and one always had to set the sysctl to
get the /dev/mixer and other symlinks generated in the DEVFS case. Instead,
change the test in pcm_addchan() to call pcm_makelinks() after the first
channel is initialized, since the aliases are linked to channel 0.

the file verifier. The NFS client is supposed to do a SETATTR after a
successful O_EXCL open/create to clean up the attributes. FreeBSD's
client code was generating a SETATTR rpc but was not generating an access
or modification time update within that rpc, leaving the file with a
broken access time that solaris chokes on (and it doesn't look very
nice when you ls -lua under FreeBSD either!). Fixed.
especially on strings passed from argv; rename system() to exec_shell(),
and make it static; use strlcpy() and make sure it works; use proper
type (size_t) to be passed to malloc()/realloc().
Use getusershell() to make sure the SHELL environment variable passed is
safe to use. Add new option -s to allow anal users to pass things like
perl; this option is here along with getusershell() checking since the
such checking is only intended to affect things like suidperl that might
call apply(1).

While there fix the layout of function headers (noticable in long headers)
Fix up some style nits. It's Perl and should be written in that style.
Bump __FreeBSD_version to reflect the move.
For the moment, <sys/select.h> includes <sys/selinfo.h> to allow
clients time to catch up.
