Since aucat supports any parameter combination sio_getcap() doesn't need to query the server for supported parameters. So stop using the AMSG_GETCAP message, and remove it completely from the aucat protocol.

Make aucat audio and midi backends share the same code to communicate with the server. As we're at it use the same protocol for midi and audio. Now, both audio and midi code use the same SNDIO_DEBUG environment variable to turn on/off DPRINTF's.

Don't send the initial position as a clock tick with a negative delta. Add a new ``initial position'' message which is simpler. No bahaviour change, except effects of the protocol version crank.

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)

When starting playback, the client tries to write ``bufsz'' frames instead of ``appbufsz'', which violates the flow control mechanism. Fix this longstanding bug by enabling negative values in AMSG_MOVE messages, this way the client is notified when its stream is attached to the mixer, and can update its max transfer limit. Since this fix changes the AMSG_MOVE message format, we crank the protocol version, and thus remove code specific to the old protocol.

Currently midi capable programs can control midi hardware, but cannot cooperate with other programs. The aim of this change is to allow any program to send midi data to other programs as they were midi hardware. For instance, this change should solve the longstanding problem of using a midi sequencer with software synthesizers. More precisely: - new midicat(1) utility (actually hardlink to aucat(1)). it creates software midi thru boxes, allowing programs to send midi messages to other programs as they were midi(4) hardware. - new midi api in libsndio (see mio_open(3)), to access midi(4) devices and midicat(1) sockets in a uniform way. - new device naming scheme <service>:<unit>[.<option>], common to audio and midi. - new sndio(7) manual describing concepts and naming The current audio device naming still works, but people having scripts or configuration files containing device names could read the sndio(7) man page and slowly start updating device names. discussed with jakemsr@ and deraadt@, help form jmc@

add a writable ``appbufsz'' field to the sa_par structure, containing the program-part of the buffer size, ie the part that is subject to underruns. Useful for apps like cdio(1) that don't have their own rings, or to apps that have a minimum ring size constraint. Setting the ``bufsz'' parameter becomes deprecated. ok jakemsr

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.
