alsa: mixer - use safe dB range values when the override mask is unset

Use safe values for the min_dB and max_dB fields when the position mask
is unset to avoid breakage for the upper levels.

If the range is incorrect, the volume range shown in pavucontrol shows
strange values.

(Thanks to Wim Taymans for the idea.)

alsa: mixer - add support up 8 mixer channels

We have at least one USB hardware which supports the 8
channels in one mixer element:

  https://github.com/alsa-project/alsa-ucm-conf/pull/25

POSITION_MASK_CHANNELS define was added for the future extensions.

The override_map variable was changed from bool to mask (unsigned int).
The channel map override settings is handled for channels up to eight now.

Also added missing override-map.3 .. override-map.8 to the configuration
parser array.

The driver channel position was added to the override mask arguments
(syntax is driver:pulseaudio like left:all-left). If ommited, the ALSA's
channel positions are guessed by index.

switch-on-port-available: Switch to headset or mic on unknown avail

On some Dell AIO machines, there is no internal mic, only a multi
function audio jack, so the only input devices are headphone-mic and
headset-mic, and they share the Jack with headphone.

When there is no headset plugged in that Jack, the headphone-mic
and headset-mic are off. And since there is no available port under
the analog input source, this source is unlinked (if there is
internal mic, the source will not be unlinked). so the only pa-source
left in the PA is analog-stereo-monitor.

After the headset is plugged, we need to let switch_to_port() handle
headset-mic and headphone-mic conditionally, this will guarantee the
source will be created if it is unlinked before plugging, and then the
input profile could be selected correctly.

alsa-mixer: Handle the index for ALSA mixer jack identifiers

Some systems have two jacks with same name but different index, we need
to take index into consideration to use both jacks.

alsa-mixer: Support dual Front Headphone Jack

There are dual Front Headphone Jacks with different indices or with
different names, they can be found on HP EliteDesk 800 SFF and HP
EliteDesk 800 DM, respectively.

alsa-mixer: Use unambiguous descriptions with dual headphone outputs

Previously both paths had description "Headphones", which I assume can
cause confusion with users who see two ports with identical names. I
don't have this kind of hardware myself nor have I heard complaints from
users, this is just something I noticed while reading the configuration
files.

alsa-mixer: Move HP EliteDesk 800 SFF/DM second headphone output to path analog-output-headphones-2

The two headphone outputs should be handled in separate paths so that
volume control can be implemented properly for both outputs.

alsa-mixer: Add support for the Headphone,1 element

This is seen at least on HP EliteDesk 800 DM and HP EliteDesk 800 SFF.

This is used by the analog-output-headphones-2 path, but all other paths
on the same sink need to handle the element too. The existing
configuration is inconsistent between files regarding whether headphone
outputs should be muted or not when not using them. I chose to be
consistent within files, which means that Headphone,1 handling is
inconsistent between files in the same way that the existing Headphone
and Headphone2 handling is. (My opinion is that unused paths should be
always muted, but I didn't want to do that policy change in this patch.)

ladspa-sink: do not call pa_sink_suspend if PA_SINK_IS_LINKED is false

While module-ladspa-sink is still being loaded and before pa_sink_put() is
called there may be an attempt to reconfigure master sink when avoid-resampling
is true. This breaks attempting to suspend ladspa-sink which is still in INIT
state.

Fix this by skipping pa_sink_suspend if PA_SINK_IS_LINKED is false.
