FILE REMOVED
Simplify internals and rewrite file header parsing code: - remove -M, -t, -w, -C, -x flags that don't make sense anymore - make "-j off" the default (sndiod already does the job) - don't limit the number of played/recorded files. - add support for floating-point encoded files. - add support for apple .aiff and sun/next .au files

Simplify and improve the way options are parsed and remove ~300 lines
of code that becomes unused. Few command line arguments changes are
required though:
- stream definitions (-ios) now must follow devices definitions they
are attached to (-fMn)
- the -n option is now a special "loopback" device and is thus used
like -f, eg it must precede streams
- in midicat, midi thru boxes are not created automatically anymore,
the new "-M" option must be used for that
- channel numbers (-Cc options) correspond always to channel numbers
of the hardware.
- the -u option isn't needed anymore
- increase the log verbosity so user errors are logged
without using -d
tested by many, help from jmc

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 traces to help tracking subtle timing bugs often causing underuns and overruns; such bugs are hard to debug with ktrace or a debugger. They are also handy to debug or monitor code using aucat. To enable traces, compile aucat with ``make DEBUG=-DDEBUG'' and use the -d option multiple times. ok jakemsr

Allow any program using aucat to act as MMC slave and MTC master transparently. Multiple audio applications can be started synchronously from external software/hardware supporting the standard Start/Stop/Relocate messages. The server clock is exposed through MTC, allowing non-audio software/hardware to be synchronized to audio applications.

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@

in server mode, create /tmp/aucat-userid/ directory with permissions 0700, and create sockets in it. This prevents one local user to eavesdrop or disturb audio programs of other users. if you're using the ``-s socket'' option with an absolute path as argument, please update it to use a socket name. requested by many, bits from jakemsr and otto 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.

factor code that discards data from abuf strucure into a single abuf_rdiscard() routine. Similarly add abuf_wcommit() routine for writing. The purpose is to stop manupulating FIFO pointers in various places outiside abuf.c, its too error prone. No behaviour change. ok jakemsr

if aucat is resumed (after suspend), kernel buffers are empty, thus write() syscall succedes and consumes aucat buffers until kernel buffers are full. If aucat buffers are smaller than kernel ones, they will underrun, and aucat will terminate, since underruns are not handled yet. This changes is an improvement until SIGCONT handler is implemented. The correct approach is to add a handler for SIGCONT to: call dev_stop(), reset all buffers, bring play and record in sync, fill play buffers and call dev_start(). 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@
