After opening a card, this command can show the name of the actually
loaded configuration file, either matches the card name or card long name.
So developers can check if there is a device-sepcific configuration file
available for a given card.

Doxygen doesn't preserve formatting that relies only on indentation,
typeset lists of identifiers explicitly.
This makes the HTML docs a lot more readable.
This change comes along the lines of commit 72aa0f8332 ("ucm: reformat
snd_use_case_get() doc").
Some TABs has been added too in order to preserve the aligned look when
reading the source code.

One jack may mute multiple devices, so let's make JackHWMute a list of
device names instead of just a single device name.

Doxygen doesn't preserve formatting that relies only on indentation.
This fixes it by using lists more liberally.
There are probably more places to fix than just
snd_use_case_get_list(), but I only have motivation for fixing this
function's documentation formatting (the next patch will add some more
content to the function's documentation).

add standard value JackDev, JackControl and JackHWMute for speaker
mute control on jack insertion. These values will be applied on
pulseaudio.

I submitted earlier a patch that made the value parameter of
snd_use_case_get() non-const, but as that changed the public API, the
patch couldn't be accepted. This is the same patch, modifying the
internal code so that there are fewer issues with constness, but the
public API is left alone (a comment was added to the function
documentation, though, so that hopefully nobody else will try to fix
the same unfixable problem).

At least PulseAudio needs special handling for dummy devices. To allow
that to happen automatically, the UCM configuration should contain the
information about which PCMs are dummy.

Playback/CaptureChannels has been around for a bit. Playback/CaptureRate
is new and is intended to be used to specify the sample rate at which
the Playback/CapturePCM should be opened.

[=]<NAME>[/[<modifier>|</device>][/<verb>]]
- value identifier <NAME>
- Search starts at given modifier or device if any,
else at a verb
- Search starts at given verb if any,
else current verb
- Searches modifier/device, then verb, then defaults
- Specify a leading "=" to search only the exact
device/modifier/verb specified, and not search
through each object in turn.
- Examples:
"PlaybackPCM/Play Music"
"CapturePCM/SPDIF"
From ValueDefaults only:
"=Variable"
From current active verb:
"=Variable//"
From verb "Verb":
"=Variable//Verb"
From "Modifier" in current active verb:
"=Variable/Modifier/"
From "Modifier" in "Verb":
"=Variable/Modifier/Verb"

At any time, one can query:
_supporteddevs/<modifier>|<device>/<verb>
_conflictingdevs/<modifier>|<device>/<verb>
If a verb is current, one can query:
_supporteddevs/<modifier>|<device>
_conflictingdevs/<modifier>|<device>
Note that at most one of the supported/conflicting devs lists has
any entries, and when neither is present, all devices are supported.
