bluez-alsa: removed the PCM hack, and build a shared lib
This removes the deprecated PCM proxy hack, and brings mandatory features for the softmixer. This change applies on top of the latest bluez-alsa master of 2018-12-04 and brings 3 patches: 1) builds a shared library and links bluez-alsa and ioplug controls & pcm to it. 2) func log by default 3) increase the number of max connections from clients (pcm & ctrls) ----- Upstream status for the patches: 1) pending. Based on a submitted PR that is not clean enough and that the maintainer does not want to take before at least 6 months https://github.com/Arkq/bluez-alsa/pull/95 2) pending. Was submitted as part of the Ofono support in bluez-alsa, but was not retained. See the original PR for Ofono for that. 3) pending. The maintainer is OK with this but wants to refactor the client-server protocol in the coming months. In a private mail of 12/06/2018: "Yes, you can increase this hardcoded limit as a temporary workaround. I've put in there (and made it rather low) as a reminder, that clients are stored in the list, which might not be optimal for larger number of connected clients. In the future bluealsa will support audio mixing, so connecting many clients to a single transport will be a common case. So, I've thought about incorporating more efficient structure for storing (in particular searching) connected client - something with log(n) search complexity. Then, it might be worth to implement this container to be dynamic with an upper capacity limit (which might be high, like 200-300 clients)."
