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

Add WARNS flag.  (It was left at my local in previous commit..)

Fix paths and flags.
- aurateconv is gone.  mulaw is a part of audio inseparably.

Bump default value of WARNS for modules from 3 to 5, and
explicitly set WARNS for modules that fail with WARNS=5.

Also, turn on -Wno-missing-noreturn for clang for some files.

At the moment, among ~ 360 modules,
- 2 (lua and zfs) need WARNS=0
- 1 (solaris) needs WARNS=1
- 136 need WARNS=3 (mostly due to sign-compare)
- 4 need WARNS=4
- others can be compiled with WARNS=5

Discussed on tech-kern.

update from HEAD

Sync with HEAD

file Makefile was added on branch tls-maxphys on 2017-12-03 11:38:59 +0000

Define the NWSMUX symbol for the spkr module (for modules, we cannot
use the wsmux.h file created by the needs-flag in sys/conf/files)

Sync with HEAD

Sync with HEAD.  (Note that most of these changes are simply $NetBSD$
tag issues.)

Create a single combined module for spkr_pcppi and spkr_audio, and
build it for all architectures.

By doing this, we can handle pcppi, audio, or both attachments with
non-built-in modules.

XXX Still to do: the module currently cannot be unloaded, and the
XXX spkr device(s) currently cannot be detached.  (Really, two
XXX sides of the same problem.)

sync with latest. this should either be called spkr_pcppi or made to work
with both busses.

Add spkr_pcppi.c

Revert to previous.  Add PCPPISPEAKER flag to fix build.

Fix building of the spkr module.  The module now is the synthesized speaker.
