c395939120 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.

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

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

bb2b9030e8 * 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.

5b45337d82 Factor out the PnP resource parser so that it can be re-used by pnpbios
and acpi.

4249382df0 This represents essentially a complete rewrite of the ISA PnP code. The
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.
