'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).

- Implement hardware volume control for the Maestro chips. This version
only handles the case where both channels are adjusted at the same time.

- The mixer_hwmute() function can be called when a soundcard receives a
mute request.
- The mixer_hwstep() function can be used to adjust the volume of one or
both channels.
- The 'hw.snd.hwvol_step' sysctl determines the amount that mixer_hwstep()
adjusts the volume by on each call.
- The 'hw.snd.hwvol_mixer' sysctl specifies the mixer device to adjust the
volume on for both functions. The values used correspond to the
SOUNDCARD_MIXER_* constants.
