Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

The OpenSL volume interface is not available for audio inputs on
Android so we apply the volume ourselves on the PCM data.

Don't use relaxed load and stores, we need to be stricter to avoid
problems with high frequency re-fills of the buffer. If we don't enforce
ordering we might end-up spending more time trying to acquire an open
slot in the buffer. Updating processes bytes is also moved off the
"OpenSL" thread.
Added some comments for improved readability.

According to our own docs we should always return 1.0 (MAX) volume level
if the device doesn't support setting the volume, which is the case
for OpenSL ES on Android.

We where very strict about tearing down the audio device. While this is
a good strategy to avoid unnecessary resource usage, it also causes
excessive re-allocations, e.g., when transiting from start to stop and
back again. This can increase latency, especially in case where a short
clip is re-played at a high frequency.
This change also decrease the chance of the player ending up in some
unknown state where it drops audio clips without any warning.

The old code was assuming that the interface was expecting power
values, while it actually uses amplitude values. In addition the
difference between the min/max values where used, resulting in
quite high gain values.
