The jack instances created in patch_sigmatel.c may be double-freed.
The device management code checks the invalid element, and thus there
is no real breakage, but it spews annoying warning messages.
But, we can't simply remove the release calls of these jack instances
because they have to be freed when the codec is re-configured.

Now, a new flag, bus->shutdown is introduced to indicate that the bus
is really being unloaded, i.e. the objects managed by the device
manager will be automatically deleted.  We release these objects only
when this flag isn't set.

The SPDIF output is toggled at each time any SPDIF status bits are changed
because of the known problems on some codecs.  But, this also results in
loosing the sync, and the problem is more obvious on HDMI output over
SPDIF.  Since the toggle is necessary only for some codecs, we should
check whether this workaround is needed and skip if unnecessary.

Added a new mixer switch to enable/disable the sharing of the default
PCM stream with analog and SPDIF outputs.  When "IEC958 Default PCM"
switch is on, the PCM stream is routed both to analog and SPDIF outputs.
This is the behavior in the earlier version.

Turning this switch off has a merit for some codecs, though.  Some codec
chips don't support 24bit formats for SPDIF but only for analog outputs.
In this case, you can use 24bit format by disabling this switch.

In some cases, the BIOS sets up only the HP pins with different assoc
and sequence numbers, e.g. on FSC Esprimo with ALC262.

This patch adds a fix-up for such a case.  When multiple HPs are defined
and no line-outs is found, the configurator tries to re-assign some pins
from HP list to line-out, judging from the sequence number.
