Add contains() function that checks if an item is in an idxset. Add
isdisjoint(), issubset(), issuperset() and equals() functions that
element-wise compare two idxsets.
Add complementary functions to the existing idxset search(), first(),
next() functions that work in the reverse direction: reverse_search(),
last() and previous().
Add steal_last() to remove and return the last item in the idxset.

The existing code meant to generate device groups for combination ports
is tightly coupled to port creation. Similar functionality would be
useful to generate nonconflicting device groups for multiple profiles as
well, so this tries to rewrite it into a more reusable state.
Several things (e.g devices, mapping contexts) use idxsets to store a
device selection. This also switches this conformance check and device
group generation to using idxsets to make it easier to work with those,
with the eventual aim to unify device group representations.
Also try to adjust users of these functions to use idxsets these will
need/return, without causing too much interference.

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.
