LC3plus expands 509 bytes input -> 7680 bytes output, which is bigger
than current decode buffer.
Make the decode buffer bigger, and put it on heap, not stack.
Codecs may need to fragment a single encoder frame across multiple
packets that are sent consecutively.
Allow codec->encode() to set need_flush=NEED_FLUSH_FRAGMENT, so that
sink should immediately call start_encode + encode with NULL input data,
to produce the next packet.
Previously, other return values than need_flush=1 were unused, so no
need to bump codec ABI for this.
We need exactly 4 hex characters, everything else is refused. We
also copy those characters directly to the output string without
assuming any encoding.
See #2337
Codec switch flag should be cleared on device connection status change,
to deal with codec_switched() callback not being called if device is
suddenly disconnected.
When device is disconnected, running codec switches are not meaningful,
and should be stopped.
The codec switch callback may also trigger A2DP profile switch, which
may reconnect the device. Fix it so this does not happen.

Make helper method to parse thread properties and add 2 new properties
to control name and stack-size of the thread.
Use properties when creating threads with the default utils.
Use the default thread utils instead of pthread_create so that the
properties are used.
Increase the FC filter frequency to 12KHz for better dialogs. This
filter is only applied when making the FC from FRONT channels so that
we keep the high frequency signal on the FRONT mostly.
Increase LFE filter frequency to make slightly more bass.
Disable widen filter by default.
Update config files with the correct defaults.
Not all string functions have a POSIX compliant locale aware version
(eg. strtof_l). Instead uselocale [1] should be used, which allows
switching the locale of a thread to a welldefined one and restoring it
afterwards.

We can't have a default that simply copies channels, that's just
wrong. So we enable PSD again.
PSD does a good job of moving the ambient sound to the back. It's
subtle and almost stereo like but it's better than plain stereo.
The stereo widen has been reduced to make it more like the simple
upmixing.
People that previously wanted the copy-channels-experience had to
manually enable this in pulseaudio so it's not too much to ask
to manually switch the algoritm to simple. I think this is a better
default.

See #2219
The PropInfo either has a registered id (and then also a name from the
type-info) or a custom name as a string.
In all cases, the description contains a free form text that clarifies
the property.
Use the description in the stream controls name.
And use this in spa_json_format_float() where we also avoid invalid
json floats.
Use json float format in some places where we serialize json floats.
Add a unit test.
See #2223
Add a property to select the upmix method. PSD is enabled by default
but a new simple upmixing algorithm is available that duplicates
channels and avoids lowpass filter on the FC and disables widening.
