Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

Remove isic(4). It is part of ISDN, which we are now retiring.

Add z3rambd to files.amigappc, hopefully this will fix amigppc build.

Fix fallout from recent ed driver replacement. Makes amigappc build again.

Port amiga calls config_console() from machdep.c now, so we have to do

Ok by releng@.

branches: 1.24.8; 1.24.12;
Include new bppcsc(4) driver from amiga.

Include new IOBZCLOCK option to make amiga/dev/ioblix_zbus.c compile again.

branches: 1.22.2; 1.22.4;
IOBlix files were missing.

Include majors.amigappc instead of majors.amiga.

Some improvements based on the work of Adam Ciarcinski.
Adapted everything to integrate with current 5.99 source.
Added an Amiga PIC for interrupt handling.

Status:
A CSPPC machine probably boots into single user, but only few devices
will attach without problems (e.g. keyboard, serial, parallel, floppy disk,
the RTC, CC graphics, sometimes Ariande ethernet and A4000 IDE.
BPPC support is prepared, but unfinished and untested (I don't own a BPPC).

A problem which has to be solved is interrupt acknowledging, which may happen
twice. Once in the amiga drivers from sys/arch/amiga/dev and then in the PPC
specific pic_amiga.c.

branches: 1.19.10;
Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

Bring some stuff up-to-date. To be continued.

pregenerate grf_ultms.c, so that gspa isn't needed during kernel build

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

Moved binary compatibility options from arch directory to cpu directory

Removed m68k OSes binary compatibility (this is a powerpc port, right?)

defflag GRF_NTCS before GRF_PAL (which has an option-dependency on
GRF_NTSC).

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to

- The new grammer ``device-major'' is introduced to ``files''.

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
