This fixes the mute/unmute logic. This was broken due to
a forgotten push for a commit

This fixes the compilation for hosts (Ubuntu, fedora, opensuse),
that do not have alsalib-1.1.6
Notice that this fix needed another one in app-template, since
the OS detection was broken.
These are the changes brought by the bump of app-templates:
(3dc85ec - Thierry Bultel) common.cmake: fixed erroneous search path for os-release
(7fa5e5a - Romain Forlot) Fix: missing gcov symbol in compiled binaries
(76e12e7 - CorentinLGS) app-templates doc: Changed doc to fit new format.
(02f45f1 - Romain Forlot) Update Docs
(52ae181 - Romain Forlot) Fix: typo
(f0b24b0 - Romain Forlot) Rollback about TEST build type
(e841a77 - Romain Forlot) Adding a TEST build type
(994ebc1 - Romain Forlot) Change default compilation options.
(85d5ffd - Romain Forlot) Test widget only if there are test materials
(d14bdce - Romain Forlot) Handles more test LABELS.
(70cf8fd - Romain Forlot) Missing flag for COVERAGE build type
(3c99b8a - Romain Forlot) Create a test widget

When a sound card has multiple devices, it is invalid to set
the slave name of the dmix as "hw:cardname" because alsa does
not know which device to use.
The fix consists in using the device number, when it is given.

This adds sound playback for incoming sound from
connected bluetooth devices.
In this version, the softmixer relies on a modified
bluez-alsa version (https://github.com/iotbzh/bluez-alsa),
that provides an ioplug PCM bluezalsa connection proxy.
The softmixer api has a new verb to dynamically set the
device to listen to:
afb-client-demo ws://localhost:1234/api?token=\uuid=123 smixer bluezalsa_dev '{"interface":"hci0", "device":"F6:32:15:2A:80:70", "profile":"a2dp"}'
In this way it is possible to switch from a bluezalsa audio source to
another without any further configuration.
For now, only interface hci0 is supported.
This commit also migrates the softmixer binding to API v3

Now uses two threads for in the playing loop
The first one reads from the capture device (ie, a phys. capture, or snd_aloop) and writes
data to a circular buffer. The second one gets data from the circular buffer and outputs
it to the playback. This model solves a lot of correlated timing bugs between read & write
tasks.
The read tasks only wakes up the write task when the buffer is 80% full.
The buffer size big enough to hold 2 seconds of sound.
The mute implementation has also been simplified, since it has been found out that it was possible
to recover from an interrupted read, by calling snd_pcm_start additionnally to snd_pcm_prepare.
Thus, the mute code consists in listening to an extra file descriptor in the read loop.
Reading from that descriptor gives the mute or unmute command sent at higher level (in the
PCM control event callback).
When a 'mute' order is get, the capture sound fd is simply backup and replaced by '-1' in the
set of the poll of the read task.
When a 'unmute' order is get, the fd is simply restored.
The start threshold is only computed for capture, and hardcoded to 1 for playback.
This removes most of the remaining EPIPE on playback.
The stop threshold has been removed. It had bad side effects on the amount of writeable
data returned by snd_pcm_avail_update (was returning too small chunks)

Uses the same logic as 'aplay' to set the start & stop
thresholds. With this fix, there are no more
periodic EPIPE errors when writing to playback

when the stream is muted (due to the configuration, or
due to a HAL request), the read/write loop is stopped.
The benefit is that muting will work with capture devices
that do not implement the mute in their driver.
The inconvenient of stopping the read loop is that it
has made appear an unexpected side-effect: the poll on
capture does not trig for further incoming frames.
The workaround is to completely close, then reopen
and configure the capture PCM.

This fixes the numerous XRUN issues seen on some cards.
The trick is to set the buffer_size & period size in
hw parameters. These ones are calculated from an expected
maximum latency.
Also, the writei is done in a loop to be robust to overruns
and partial writes.
