aucat (server):
- make the ``-m mode'' option per subdevice, allowing
subdevices to be play-only or rec-only even if the
server is full-duplex
- add ``monitoring'' mode (with ``-m mon''). This is a
record-only stream from which played streams can be
recorded (kind of ``record what you hear'').
- allow MIDI devices to be subscribed to the controlling
MIDI port of the server, ie what midicat does (with -f
option), but using the -q option.
- add flow control to the protocol, and serialize clock
ticks (sio_onmove() calls) and data chunks. This should
fix certain full-duplex programs, broken with ``magic''
block/buffer size combinations.
- enable 3 block latency which is the minimum theoretical.
Make -z and -b options correspond to device parameters.
- make sio_getcap(3) the same for aucat and sun backends,
ie return whatever is supported (``everything'' in the
aucat case, since everything is actulally supported).
aucat (player):
- enable ``-m mode'' option to select between monitoring
and recording when ``-o file'' is used.
- plug MIDI code to non-server codepath. The MIDI control
device is specified with the ``-q device'' option, as in
server mode.
- impliment lseek()'ing within files (controlled
through MIDI). Necessary to use aucat with a MIDI
sequencer.
midicat (thrubox):
- rename ``-f'' flag to ``-q'', so it has the
same name as in aucat (-f is still working)

add minimal server capability to aucat(1). When started in server mode, it listens on an unix socket and mixes/demultiplexes any number of full-duplex streams, doing necessary format conversions and resampling on the fly. programs can use the new libsa(3) library to play and record audio. The library provides a very simple API to connect to the audio server; if aucat(1) isn't running, it uses the audio(4) driver transparently instead.

move all device related stuff from aucat.c to a new dev.c file. The new dev_xxx() routines expose a "high level" self-contained interface to the device. At initialization, the device is opened and two chains of aproc structures are created: * a playback chain that exposes a (initially) empty mix aproc to which the rest of the code can attach new streams to be played * record chain that exposes a (initially) empty sub aproc to which the rest of the code can attach new stream to to record The rest of the code, has just to use dev_attach() routine to attach streams. While we're at it, add a ``devops'' structure containing pointers to the device-specific routines. This will allow later to add support for other type of device than the Sun API. Also, write the .wav headers in file_del(), so put all header related data in the file strucuture. This allows to close() the file, as soon as wpipe_xxx() aproc terminates. This will be useful for the server, because it will need to close() descripts of closed connections immediately. add mix_pushzero() routine to fill the mixer with silence. It will be used to avoid the mixer to underrun when there are no input streams. Since we always have at least one input stream there's no behaviour change. ok jakemsr

add support for: - recording, full-duplex operation - format conversions and resampling on the fly - mixing on the fly of multiple inputs of different formats - up to 16 channels, simplistic "routing" of channel ranges - more linear encodings (in raw and wav files) the old behaviour is fully preserved if none of the new -i and -o options are used. code and fixes from jakemsr@ and eric@, suggestions by others. ok "go ahead" deraadt@
