kernel: Fix some wrong porting of *_TRYLOCK() macros.

Of these three, only CHN_TRYLOCK() is used in actual, active code,
but it is in the SNDCTL_DSP_SYNCSTART ioctl which in turn is not
used in base or in dports.

ARCMSR_LOCK_TRY() and PCM_TRYLOCK() are not used at all.

sound - Fix default & unit specs for /dev/dsp and /dev/mixer

* /dev/dsp{0,1} was overriding the unit number and forcing the currently
set default dsp unit, so it didn't matter if you specified /dev/dsp0 or 1,
it still used hw.snd.default_unit.

* Get rid of the devfs aliasing for /dev/dsp and /dev/mixer. Instead, use
the cloner code to lookup the default dsp and default mixer when /dev/dsp
or /dev/mixer is opened.

This simplifies default handling significantly.

sound: Make device cloning work

* Some lockstatus() calls were wrong and needed to be compared
with LK_EXCLUSIVE

* The sound device caches dynamically created devices and tries
to reuse them, but devfs got angry if the clone code passed
it a device which was already in the filesystem namespace. devfs
had to be modified in 2c94b9eeb85c6cfa5ff918aa58ce484b27fc7c91
and eb1c7cbc9e1052820efc6b0b7a94c40a7d45b329

* The clone code was designed to clone to new unit numbers, not
clone an existing unit into multiple channels

Fix pcm unit translation so /dev/dspN actually maps to pcmN. Before
e.g. /dev/dsp* all mapped to pcm0.

At this point the sound device can be used, albeit by only one
application at the same time.

* snd_au88x0 has been removed. According to the FreeBSD commit message, it
never even got compiled into the kernel or as a module.

* Drop the ds1, csa and maestro3 drivers due to restrictive license terms
or the need to use binary blobs. These drivers are not built by default
on FreeBSD.

This removes the following modules:

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

Fix the way <sys/ioccom.h> is included throughout our tree.

The original intention was to include it only in header files which
define ioctl codes and not in .c or .h files which include headers
that define ioctl codes.

Adjust the tree to follow this idea.

Call selwakeup() from an MP-protected taskqueue.

Before, we would call selwakeup() from interrupt context. This
was working as long kern.intr_mpsafe == 0. selwakeup() however needs
the MP lock held, so we can't call it directly from the interrupt
when running with kern.intr_mpsafe=1.

Instead, perform the wakeup from a "bottom half" taskqueue SWI to make the
sound devices intr_mpsafe, as they claim to be.

Allow vchans to have their own volume control.

This means you can use two processes producing audio and change their volume
independently (if they implement mixer controls themselves).

Say hello to a sound system update from FreeBSD. This includes the long
awaited Intel High Definition Audio (HDA) a.k.a. Azalia support.

The generic sound support module has been renamed to sound.ko and the
"everything included" module is called snd_driver.ko now. Apart from
that, everything should continue working as normal, just better.

Do a major clean-up of the BUSDMA architecture. A large number of
essentially machine-independant drivers use the structures and definitions
in machine-dependant directories that are really machine-independant in
nature.

Split <machine/bus_dma.h> into machine-depdendant and machine-independant parts
and make the primary access run through <sys/bus_dma.h>.

Remove <machine/bus.h>, <machine/bus_memio.h> and <machine/bus_pio.h>. The
optimizations related to bus_memio.h and bus_pio.h made a huge mess,
introduced machine-specific knowledge into essentially machine-independant
drivers, and required specific #include file orderings to do their job.
They may be reintroduced in some other form later on.

Move <machine/resource.h> to <sys/bus_resource.h>. The contents of the file
is machine-independant or can be made a superset across many platforms.

Make <sys/bus.h> include <sys/bus_dma.h> and <sys/bus_resource.h> and
include <sys/bus.h> where necessary. Remove all #include's of
<machine/resource.h> and <machine/bus.h>. That is, make the BUSDMA
infrastructure integral to I/O-mapped and memory-mapped accesses to devices
and remove a large chunk of machine-specific dependancies from drivers.
bus_if.h and device_if.h are now required to be present when using <sys/bus.h>.

Replace the the buffer cache's B_READ, B_WRITE, B_FORMAT, and B_FREEBUF
b_flags with a separate b_cmd field. Use b_cmd to test for I/O completion
as well (getting rid of B_DONE in the process). This further simplifies
the setup required to issue a buffer cache I/O.

Remove a redundant header file, bus/isa/i386/isa_dma.h and merge any
discrepancies into bus/isa/isavar.h.

Give ISADMA_READ/WRITE/RAW their own independant flag definitions instead of
trying to overload them on top of B_READ, B_WRITE, and B_RAW. Add a
routine isa_dmabp() which takes a struct buf pointer and returns the ISA
dma flags associated with the operation.

Remove the 'clear_modify' argument to vfs_busy_pages(). Instead,
vfs_busy_pages() asserts that the buffer's b_cmd is valid and then uses
it to determine the action it must take.
