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.

PulseAudio ALSA modules report errors after calling
snd_pcm_avail_delay(), with a delay lower than the number of samples
available.
Correct delay using Jaroslav's recommendation:
"the result should be 'delay(slave) + mmap_capture_avail(pcm)"

If we try to print this then it causes a read past the end of the array
in snd_pcm_type_name().

For capture stream, the delay must be obtained as last, but we need to
update the ring buffer pointers for the avail_update call. So, rearrange
the code a bit and add hwsync call as first.

Fix required before interrupt disabling routines patch can be applied.

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
time). However, ltmain.sh is copied into the ${srcdir} by libtoolize and
should be safe to check at any time that configure can be run.

For TLV information that indicates that the minimum value is actually
muted, the returned range used the wrong minimum dB value, and
converting dB values to raw control values did not round up correctly
near the minimum.

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.
