6008862bc2 Change callers of mtx_init() to pass in an appropriate lock type name. In
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

Tested on:	i386, alpha, sparc64

995231304d - Provide toggles to show debug messages. Set new sysctl variables
hw.midi.debug and hw.midi.seq.debug to 1 to enable debug log.

- Make debug messages human-frendly.

- Implement /dev/music.

- Add a timer engine required by /dev/music.

- Fix nonblocking I/O.

- Fix the numbering of midi and synth devices.

05331bc6d4 - Do not uiomove with a mutex locked.
- Move from msleep/wakeup to condvar.

- Return either zero or a positive errno value from a function.
  Return additional result via references.

- Unify the typedef of callback functions.

Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

46700f1259 Use INTR_TYPE_AV for the interrupt handlers because:
1: most drivers are sensitive to timing, and
2: the handlers are MPSAFE and need a chance to get into the kernel
before some other non-mpsafe handler blocks the ithread on Giant in
shared irq cases.

87a636ccb0 - Mutexify midi(4). The driver runs under the giant lock by default.
If you ever want to run midi(4) out of the giant lock, uncomment
MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS
and INVARIANTS.

- midi_info, midi_open and seq_info are now tailqs, allowing arbitrary
numbers of devices to be configured.

- Do not send an active sensing message to reset midi modules.

- Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated
upon initialization.

fb0ef52838 Finally merge newmidi.
(I had been busy for my own research activity until the last weekend)

Supported devices:

SB Midi Port			(sbc + midi)
SB OPL3				(sbc + midi)
16550 UART			(midi, needs a trick in your hint)
CS461x Midi Port		(csa + midi)

OSS-compatible sequencer	(seq)

Supported playing software:

playmidi			(We definitely need more)

Notes:

/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).

EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.

TODO:

MSS/PCI bridge drivers
Midi-tty interface to support general serial devices
