ucm: modifiers names must be compound parse
Modifier names must end in a .index to ensure we can support
same named modifiers. However the modifier index will be for internal
use only and the client will not use the index when setting modifier.
The modifier selection for same name modifiers will be based upon supported
device.

Version-check libtool correctly when doing an out-of-tree build
libtool is only created at the end of ./configure, so it doesn't make
sense to grep it in ./configure (the check would always fail the first

should be safe to check at any time that configure can be run.

ucm: core - Add initial Use Case Manager support.
This patch adds audio Use Case management support to alsa-lib.
UCM is designed to abstract the audio device hardware mixer controls into
high level abstract use cases.
The use case manager works by configuring the sound card ALSA kcontrols to
change the hardware digital and analog audio routing to match the requested
device use case. The use case manager kcontrol configurations are stored in
easy to modify text files.

Some broken applications like Audacious don't set any timing parameters.
While the alsa-lib behaviour is to select the smallest period size and
biggest buffer size, the result is the generation of thousands
interrupts per second.
If user asks for 1dB the snd_tlv_convert_from_dB will not find
the raw value, since the 1dB is not part of either range.
To fix this, we will store the previous non maching range's
maximum raw value. If the dB value is not found in the next range,
we will check, if the requested dB value is in between the current
and the previous range, and if it is than pick the apropriate raw
value based on the xdir (up or down rounding).
