- There's no need to overwrite the default device method with the default one. Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily. Discussed with: jhb, marcel - While at it, use DEVMETHOD_END. Discussed with: jhb - Also while at it, use __FBSDID.

Sound Mega-commit. Expect further cleanup until code freeze.
For a slightly thorough explaination, please refer to [1] http://people.freebsd.org/~ariff/SOUND_4.TXT.html .
Summary of changes includes:
1 Volume Per-Channel (vpc). Provides private / standalone volume control unique per-stream pcm channel without touching master volume / pcm. Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for backwards compatibility, SOUND_MIXER_PCM through the opened dsp device instead of /dev/mixer. Special "bypass" mode is enabled through /dev/mixer which will automatically detect if the adjustment is made through /dev/mixer and forward its request to this private volume controller. Changes to this volume object will not interfere with other channels.
Requirements: - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which require specific application modifications (preferred). - No modifications required for using bypass mode, so applications like mplayer or xmms should work out of the box.
Kernel hints: - hint.pcm.%d.vpc (0 = disable vpc).
Kernel sysctls: - hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer bypass mode. - hw.snd.vpc_autoreset (default: 1). By default, closing/opening /dev/dsp will reset the volume back to 0 db gain/attenuation. Setting this to 0 will preserve its settings across device closing/opening. - hw.snd.vpc_reset (default: 0). Panic/reset button to reset all volume settings back to 0 db. - hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value.
2 High quality fixed-point Bandlimited SINC sampling rate converter, based on Julius O'Smith's Digital Audio Resampling - http://ccrma.stanford.edu/~jos/resample/. It includes a filter design script written in awk (the clumsiest joke I've ever written) - 100% 32bit fixed-point, 64bit accumulator. - Possibly among the fastest (if not fastest) of its kind. - Resampling quality is tunable, either runtime or during kernel compilation (FEEDER_RATE_PRESETS). - Quality can be further customized during kernel compilation by defining FEEDER_RATE_PRESETS in /etc/make.conf.
Kernel sysctls: - hw.snd.feeder_rate_quality. 0 - Zero-order Hold (ZOH). Fastest, bad quality. 1 - Linear Interpolation (LINEAR). Slightly slower than ZOH, better quality but still does not eliminate aliasing. 2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC quality always start from 2 and above.
Rough quality comparisons: - http://people.freebsd.org/~ariff/z_comparison/
3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be directly fed into the hardware.
4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.
5 Transparent/Adaptive Virtual Channel. Now you don't have to disable vchans in order to make digital format pass through. It also makes vchans more dynamic by choosing a better format/rate among all the concurrent streams, which means that dev.pcm.X.play.vchanformat/rate becomes sort of optional.
6 Exclusive Stream, with special open() mode O_EXCL. This will "mute" other concurrent vchan streams and only allow a single channel with O_EXCL set to keep producing sound.
Other Changes: * most feeder_* stuffs are compilable in userland. Let's not speculate whether we should go all out for it (save that for FreeBSD 16.0-RELEASE). * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org> * pull out channel mixing logic out of vchan.c and create its own feeder_mixer for world justice. * various refactoring here and there, for good or bad. * activation of few more OSSv4 ioctls() (see [1] above). * opt_snd.h for possible compile time configuration: (mostly for debugging purposes, don't try these at home) SND_DEBUG SND_DIAGNOSTIC SND_FEEDER_MULTIFORMAT SND_FEEDER_FULL_MULTIFORMAT SND_FEEDER_RATE_HP SND_PCM_64 SND_OLDSTEREO
Manual page updates are on the way.

Rename the sound device drivers:
- `sound' The generic sound driver, always required.
- `snd_*' Device-dependent drivers, named after the sound module names. Configure accordingly to your hardware.
In addition, rename the `snd_pcm' module to `sound' in order to sync with the driver names.

many changes:
* add new channels to the end of the list so channels used in order of addition
* de-globalise definition of struct snddev_info and provide accessor functions where necessary.
* move the $FreeBSD$ tag in each .c file into a macro and allow the /dev/sndstat handler to display these when set to maximum verbosity to aid debugging.
* allow each device to register its own sndstat handler to reduce the amount of groping sndstat must do in foreign structs.

Use INTR_TYPE_AV for the interrupt handlers because: 1: most drivers are sensitive to timing, and 2: the handlers are MPSAFE and need a chance to get into the kernel before some other non-mpsafe handler blocks the ithread on Giant in shared irq cases.

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.

Update for pnp adjustments regarding NPNP.
Also, optimize out a mess of #if's that were duplicating work already done by config(8). For example, if a file is marked as "dev/sound/pci/foo.c optional pcm pci" then it's only added if pcm *and* pci are present, so #if NPCM > 0 and #if NPCI > 0 are totally redundant. A bit more work is still needed.

Remove the 'ivars' arguement to device_add_child() and device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree.
