[pulseaudio-discuss] [PATCHv2 3/7] alsa: add ucm data structures and calls

The UCM stores the mixer settings per use case in configuration files, these
files contains information such:
- list of use case verbs per card or machine
- supported devices per use case verb
- use case sink device
- use case source device
- hardware playback volume control id (per use case verb and device)
- hardware playback mute switch id
- hardware capture volume control id
- hardware capture mute switch id
The new ucm data structures are used to store that info so it can be used by
pulseaudio.
This patch also adds ALSA UCM (Use Case Manager) calls.
It checks if UCM is available for each card and if found, scans each UCM
property verb, device and modifier for the card. It then then creates
mappings for each supported UCM verb and device so that changes to the
pulseaudio profile cause corresponding changes to the UCM verb and
device for the card.
