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.

sys: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

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.

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.

"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.

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
