The async unlink behavior has been working over years.  The option was
provided only as a workaround for 2.4.x kernel.  Let's get rid of it.

This is a merge of a topic branch containing the support for the new
channel map API using control elements.

Set the default value of position_fix -1, and allow user passing
position_fix=0 explicitly to set the "auto" position-fix mode.
Otherwise the auto mode may be switched to others like COMBO of
VIACOMBO when the controller prefers it, thus user can't set the auto
mode any longer.

Also updated the documentation appropriately, too.

For following the standard, define more channel map positions and
shuffle the items a bit:

- As both PulseAudio and gstreamer define MONO channel position
  explicitly, we should follow that, too.  The mono streams point to
  this channel position unless they are explicitly assigned to certain
  channel positions.

- Top-front-* and Top-rear-* positions are added, carried from
  PulseAudio's definitions.

- Move NA and MONO definitions at the top of table right after
  UNKNOWN, since these are more abstract in comparison with other
  practical positions.

There is already a set of channel position definitions in alsa-lib
mixer.h, and it'd be more practical to keep the same order for the
PCM channel map, too.  The value is shifted with 1 to keep zero for
UNKNOWN.

Added a simple support of automute for the front HP jack to AD1882
stack model.  Such an addition is basically an exception -- we really
want to avoid the static quirk codes, but AD1882 parser isn't still
ready for moving to the BIOS auto-parser yet.  So, as a quick fix, I
merged it for now.

In near future, we really need the big clean up of patch_analog.c to
move on to the auto-parser...

On recent kernels, Realtek codec parser tries to optimize the routing
aggressively and take the headphone output as primary at first.  This
caused a regression on VAIO Z with ALC889, the silent output from the
speaker.

The problem seems that the speaker pin must be connected to the first
DAC (0x02) on this machine by some reason although the codec itself
advertises the flexible routing with any DACs.

This patch adds a fix-up for choosing the speaker pin as the primary
so that the right DAC is assigned on this device.
