Seigo Tanimura 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
