Add openaptx package to the OS

Description

Bluetooth audio is based on bluez-alsa, which can support SBC codec by default, and also aptx and aac when they are available.

aptx is the most popular at the moment; SBC is of lower quality.

The openaptx package is needed by bluez-alsa at build time to have aptx support.

Unfortunately there is currently no recipe to build this package.

FFmpeg mentions the legal/patent issue here, https://www.ffmpeg.org/legal.html

For information, the apt-x codec is already in ffmpeg since several months.

ffmpeg does not mention any legal issues.

Let's just keep that in a corner for now, at least we have something to reply to users if they ask.

Thanks Tanikawa-san, this sounds weird that a reverse engineered code can be affected by a proprietary license.

Apparently this is because the algorithm itself is patented. Patents on algorithm do no exist in Europe, but only in US, AFAIK.

In my understanding, apt-X is a proprietary audio codec owned by Qualcomm.
As far as I know, the encoder is already opened for Android O and released as part of AOSP, but decoder is still proprietary.
