nia | libossaudio: Various OSSv4 fixes to allow reference programs to compile
- Define various new AFMT_*. These are not returned as supported
formats by SNDCTL_DSP_GETFMTS, because it would be very silly to
have Vorbis in the kernel.
- Implement PLAYTGT and RECSRC. For each NetBSD audio device
we only return one playback and recording source, "primary".
- Return preferred channel configuration in capabilities.
Either DSP_CH_STEREO, DSP_CH_MONO, or DSP_CH_MULTI
depending on the current hardware format.
- SNDCTL_DSP_HALT_* simply flushes the audio device.

nia | branches: 1.33.2;
Add some missing channel order related ioctl defines.
These are no-ops (unimplemented) on both FreeBSD and Solaris
and the one piece of code I've found that uses it seems to assume the
call will fail so it should be safe to leave this returning EINVAL.
However, it does need the definitions to compile...

nia | ossaudio(3): Add SNDCTL_DSP_CURRENT_(I|O)PTR
In OSSv4 these are supposed to avoid the wrapping problems with the
older GET(I|O)PTR ioctls but we don't quite get the same benefit here.
XXX: We could probably fake it by maintaining some state in-between calls.

nia | ossaudio(3): Add initial support for the OSSv4.1 Mixer API
One or two calls from this API were supported previously and have been
moved to the correct place.
Mapping the controls correctly is a difficult task. There is a define
hidden in the OSS headers that would allow an AUDIO_MIXER_SET control
to be represented perfectly, but it seems to _only_ exist there, and
no software supports it. So for now only one member of a set can be
set at a time - unfortunate. I've hidden code that should unlock
doing this the proper way under #notyet.
I'm not too happy with the way this code is managing file descriptors.
Currently it has to open a new fd for each ioctl due to OSSv4 deciding
to specify the device number in a structure rather than in the filename.
In the future, we could reuse the file descriptor if the correct one is
detected open.
This allows the mixer programs provided with the OSSv4 sources to compile
and work cleanly. I've observed problems with it failing to work on
secondary devices, and should investigate this later. There may be
a fd leak somewhere.

nia | ossaudio(3): Add SNDCTL_DSP_COOKEDMODE, SNDCTL_DSP_GETERROR
SNDCTL_DSP_COOKEDMODE simply always returns 1.
"Cooked mode" is a silly way the OSSv4 authors chose to refer to allowing
for reprocessed streams. The NetBSD kernel always performs format
conversion and it can't be turned off.
SNDCTL_DSP_GETERROR provides access to the read/write over/underrun
counters. There are other things it might return, but they don't make
sense for our implementation.

nat | branches: 1.23.2;
Adds ioctls and defines for OSSv4 compatibility.
The ioctl definitions and accompanying structures were
taken from FreeBSD's soundcard.h, hopefully providing
some binary compatibility.
The ioctls are as follows:
SNDCTL_SYSINFO: Returns a structure containing
details about the audio device.
SNDCTL_ENGINEINFO - SNDCTL_AUDIOINFO: Returns a
structure with playback/recording
characteristics.
SNDCTL_DSP_GETPLAYVOL, SNDCTL_DSP_SETPLAYVOL,
SNDCTL_DSP_GETRECVOL, SNDCTL_DSP_SETRECVOL:
Retrieves/Sets Playback/Recording volume.
SNDCTL_DSP_SKIP - SNDCTL_DSP_SILENCE: These ioctls
were intended to manipulate the underlying
audio buffer skip or insert silence. These
return EINVAL.
SOUND_VERSION is unchanged, but is definable, It will be
changed when the mixer OSSv4 ioctls are written.

kleink | Determine the 'native' endianness using _BYTE_ORDER from

The previous method of wrapping a definition of _POSIX_SOURCE around the
inclusion of other headers to reduce namespace pollution had the
side-effect of not all required identifiers being defined when included
thereafter by the application itself (due to multiple-inclusion protection),
and is not blessed by that standard.
