Minor KNF along the way.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

isaki | branches: 1.1.2;
file linear.c was initially added on branch isaki-audio2.
|
| 1.1.2.1 |
| 21-Apr-2019 |
isaki | Reimplement audio subsystem.
http://mail-index.netbsd.org/tech-kern/2019/04/01/msg024944.html
At first step, audio and devices tightly coupled to audio.
audio.c -> dev/audio.c: completely rewritten.
mulaw.c -> audio/mulaw.c, audio/alaw.c: improve quality.
audiovar.h, mulaw.h: should be removed.
audio/linear.c: efficient new linear-linear converter.
auconv.[ch]: should be removed but need some functions for now.
aurateconv, auvolconv: removed (new audio.c handles it).
audiobell.c: efficient and small new bell driver.
audiobelldata.h: removed 4KB sine wave data.
pad/pad.c: catch up audio, but not cloneable for now.
