Do not abort in snd_xxx_close() functions
Remove several memory leaks by not aborting prematurely from a
snd_xxx_close() function when some operation fails.
This can happen when a USB device was unplugged.

Remove bad assert
From: Pierre Ossman <drzeus-list@drzeus.cx>
Freeing the global config update structure when it had been created
without any configs present caused an assertion to trigger. Since this
is a valid scenario and the assertion didn't really protect against
anything, it should simply be removed. Attached patch does exactly that.

pcm - fix the buffer allocation for NONINTERLEAVED mmap access
The previous code did not allocated a separate buffer for all channels
when a NONINTERLEAVED access was used. The result was that only one
"shared" buffer was incorrectly allocated.
Also, the code was a bit cleaned (cosmetic change only).

dmix: add S24_3LE support
Add to the dmix plugin support for the S24_3LE sample format which is

The optimized assembler version uses only 23 bits for sample data so
that the lowest bit can be used for synchronization because there is no
24-bit cmpxchg instruction.

seq: reorganize sequencer client numbers

Allow partial build with selected components
Add --enable-* and --with-pcm-plugins configure options for partial builds.
User can choose the core components (pcm, mixer, rawmidi, hwdep, seq, instr)
via --enable-xxx or --disable-xxx option. As default, all components are
enabled.
The PCM plugins to build can be selected via --with-pcm-plugins option.
For example, to build only rate and linear plugin, pass
--with-pcm-plugins=rate,linear
Passing "all" will select all plugins (it's the default value).
The plug plugin will select linear and copy plugins automatically.
The other auto conversions of plug plugin are enabled only when the
corresponding plugin is selected.

abort snd_pcm_dmix_drain when state is SND_PCM_STATE_XRU
From: Sascha Sommer <saschasommer@freenet.de>
this is a fix for bug 0001559.
Unlike my first guesses the real problem is not in the kernel driver but in
alsa-lib. Whenever the current dmix status is xrun and snd_pcm_dmix_drain
gets called the process will hang forever in the poll function. The reason is
that poll gets called even though the timer already stopped.
As described in the bugtracking system this bug was not noticable with alsa
versions that used the old IOCTLS because the SNDRV_TIMER_IOCTL_STOP ioctl
never reached the timer kernel module.
Attached patch fixes this problem for alsa-lib 1.0.10 by simply calling
snd_pcm_dmix_drop when snd_pcm_dmix_drain gets called in the state
SND_PCM_STATE_XRUN.

While working on an ALSA driver for the audio part of em8300-based MPEG

swapped, and B preambles should only be used on even subframes. The
