When resuming from suspend, prime play buffers with silence, otherwise the client would underrun by more than its own buffer size, which currently is not allowed (causes the client to deadlock). Set the minimum client buffer size to two blocks. Single block buffers don't work properly yet. with help from jakemsr

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

if the device is dying, don't try to stop it, otherwise this would trigger the code to free() it, which will try to stop it, and so on

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@

make the code "more correct": add reference counters to aproc structures so we can keep a pointer to the device. Beside some simplifications, this allows to easily handle the situation where the audio device desappears. No change in the behaviour.

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

When resampling, don't require the sample frequency to be an integer. This removes the arithmetic constraint between the sample frequency and the block size and all the associated code. Now aucat can work in server mode with any block size. ok jakemsr

expose the block size in the sndio API by making par->round writable and thus remove the ugly rate <-> block-size table from sio_setpar(3). Handle the block size negociation in aucat(1), since it has few constrains the code is overally simpler. ok jakemsr@, major crank suggested by deraadt@

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.
