Use __FBSDID().

Properly put macro args in ().

Rework the ISA PnP driver pnp and the PnP resource parser to fix
the following bugs.

- When constructing a resource configuration, respect the order
in which resource descriptors are read, in order to establish
the correct mapping between the descriptors and configuration
registers.
"Plug and Play ISA Specification, Version 1.0a", Sec 4.6.1, May 5,
1994. "Clarifications to the Plug and Play ISA Specification,
Version 1.0a", Sec 6.2.1, Dec. 10, 1994.

- Do not ignore null (empty) descriptors; they are valid descriptors
acting as filler.
"Clarifications to the Plug and Play ISA Specification, Version 1.0a",
Sec 6.2.1.

- Correctly set up logical device configuration registers for null
resources.
"Clarifications to the Plug and Play ISA Specification, Version 1.0a"

- Handle null resources properly in the resource allocator for the
ISA bus.

Convert more malloc+bzero to malloc+M_ZERO.

Ignore resources with a size of 0, as these are disabled (and we don't
deal with them properly elsewhere).

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
Modules

Don't record an irq mask if its empty - it confuses the resource allocator.

Remove unneeded #include <sys/kernel.h>

Allow MAXDEP dependants, not MAXDEP-1.

Don't use too-large stack buffers.

Fix PnP memory range calculations.

* Add some verbose logging to the PnP parser and fix a couple of bugs.
* Move pnp_eisaformat() to pnp.c, declared in <isa/pnpvar.h>.
* Turn the pnpbios code into an enumerator for the isa bus. This allows
all devices known to the bios to be probed automatically.

Currently the pnpbios code is dependant on the PNPBIOS option. As the code
is tested more and when more drivers are converted this will be made the
default. I have PnP changes in the wings for fdc, atkbd, psm, pcaudio, and
joy. Sio already works with pnpbios.

Factor out the PnP resource parser so that it can be re-used by pnpbios
and acpi.
