Mark a non-critical memoryleak with XXX comment

Put an XXX: comment here to point out a couple of free() issues on
pnp_read_bytes().

Spotted by: FlexeLint

Added some buggy PC-98 PnP cards support.

- Do not hang if the resource allocation fails.
- Add another quirk entry of SB AWE64.

Handle "identifier strings" right. Each ISA PnP card must have a
mandatory "card" identifier string. A logical devices on the ISA PnP
card may optionally have a "device" identifier string. Do not confuse
them.

The "card" identifier string is assigned to a logical device as the
default description string when the device is found. (If the "card"
identifier string has not been found, use the EISA PnP ID string.
Strictly speaking, this is an error.) We will override it when a
"device" identifier string is found later.

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.

* Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
which call busspace.
* Rework pci config accesses to route through the pcib device instead of
calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

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.

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

* 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.

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