Update sound-related manpages to account for the recent change in device and module naming. The following files were repo-copied: csa.4 -> snd_csa.4 gusc.4 -> snd_gusc.4 maestro3.4 -> snd_maestro3.4 sbc.4 -> snd_sbc.4 uaudio.4 -> snd_uaudio.4 The pcm(4) manpage wasn't renamed to sound(4) as there are nearby plans to rename "device sound" to "device snd", to address the ambiguity in naming, so pcm.4 is linked to sound.4 for the moment. (We also mumble something about the future plans in the manpage.) Removed links from pcm.4 to als4000.4 and emu10k1.4 -- they now have their own snd_*.4 manpages. Fixes for recent snd_*.4 manpages: added missing "device sound" to the SYNOPSIS, fixed hints (they are still "hint.pcm.<unit>" in most cases). MT5 after: 3 days

.Sh DESCRIPTION
The
.Nm
driver provides support for the ESS Maestro3 and Allegro-1 sound chips
under the PCM framework.
These chips are mostly found in laptop computers and feature an AC97 mixer,
a multi-channel sample rate converter that can mix up to four digital audio
streams in hardware, recording support, and external volume control buttons.
.Pp
The firmware for the sound processor is licensed under the GNU Public

The driver has no way of determining this configuration, so a hint may be
used to override the default guess.
