Add a "device number" component in sndio(7) device names, allowing a
single aucat instance to handle all audio and MIDI services. Since
this partially breaks compatibility, this is a opportunitiy to fix few
other design mistakes (eg ':' being used by inet6, type name vs api
name confusion, etc..). This leads to the following names:
type[@hostname][,unit]/devnum[.option]
The device number is the minor device number for direct hardware
access (ie the 'N' in /dev/audioN). For aucat, this is the occurence
number of the -f (or -M) option.
There's a compatibility hook to keep old names working if only one
aucat server is running.

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

Handle all streams the same way because there's no actual difference between audio files and client connections. Clean up the way command line options are handled and clarify this in the manual page: stream parameters (-Ccehjmrtvx) must precede stream definitions (-ios) and per-device parameters (-abz) and stream definitions (-ios) must precede device definitions (-f). Since there's no ``server'' and ``non-server'' modes anymore, make the -l option just detach the process. ok and help from jakemsr and jmc

Allow the audio device to be opened only while it's actually used. This is necessary for uaudio devices, for instance to start aucat before the device is plugged. Or to unplug a device whithout having to restart aucat when another device is plugged. This is controlled with the new -a option. Allow multiple audio devices to be used concurently, i.e. multiple ``-f devname'' options to be used; -f options must follow per-device options, which is what we do for other options.

adds the necessary bits to join channels (ex stereo->mono) or expand channels (ex mono->stereo). It's switched on/off with the ``-j'' option, (default is "on").

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.

Branch: MAIN
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@
