After previous patches, we should be generating no combination ports, so
we don't need to store multiple devices per mapping. Simplify the code
based on this.

A previous commit makes mapping names depend on the UCM device name.
Since UCM device names are unique, this means a mapping will at most
have one port and thus no combination ports can be generated.
This removes the dead code in the pa_alsa_ucm_add_ports_combination()
function, unrolls the remaining code in its helper functions that it
used, and renames it to pa_alsa_ucm_add_port() to signal that it no
longer generates combinations.

Currently each UCM verb generates one profile named the same as the
verb, meaning it's trivial to know which verb the profile belongs to.
This will be slightly harder to do when we generate multiple profiles
per UCM verb (e.g. to make use of conflicting devices).
It would still be possible to parse the profile name to get the UCM
verb, but instead let's keep track of the struct instance representing
the profile's associated verb. This also lets us remove a block of code
searching for the verb by its name.

instead of combined devices.]

While switching profiles, it's possible that we will want to do more
work besides switching UCM verbs. The alsa-card module already has our
profiles as structs, but passes in only the names instead of the entire
struct. Make things work with the struct instead, so we can add other
things (like a UCM context) to it and use those here.

Modifiers currently keep their conflicting and supported devices's
names, and these names are resolved to devices every time we need to use
them. Instead, resolve these device names while creating the modifier
struct and keep track of the resulting device structs in idxsets, same
as how device structs keep track of their support relations.

Strip the alibpref from the device string in the mapping name. This
name is used to generate the node name eventually and we don't want
this random identifier in it.
Fixes#1362
libacp is a port and wrapper around the pulseaudio card profile code.
It uses a set of templates for construct a card profile and mixer port
settings. It also has support for UCM when available for the hardware.
