Give up com.noisepages.nettoyeur:midi and reimplement Midi (#129)

[joebowbeer]

• Give up com.noisepages.nettoyeur:midi

Reimplement Midi adapters using Android Midi API,
reusing Peter's (from/to)WireConverters coming from: https://github.com/nettoyeurny/btmidi/blob/master/AndroidMidi/src/com/noisepages/nettoyeur/midi/

• Midi adapters: handle multiple devices, and javadoc-ument code

[joebowbeer]

This is @Ant1r's reimplementation of MIDI along with some build fixes / upgrades that I added.

However, the minimum ndkVersion supported by the minimum Ubuntu runner is now erroring on usleep and clock_gettime:

• Fix "implicit declaration" compiler warnings  nettoyeurny/opensl_stream#2
• pd-for-android compilation errors in opensl_stream.c nettoyeurny/opensl_stream#5

We need to fix the build before we can merge.

@Ant1r @tkirshboim Can someone create a PR to update libpd with the "fixed" (hopefully) opensl_stream code?

[Ant1r]

I can take care of it. Maybe @danomatika can handle this quick update?

[danomatika]

@Ant1r Actually, would you like to maintain this repo? I really have had nothing to do with it.

[Ant1r]

We were talking about libpd repo.

We would need to update the opensl module.

(actually I think this module should probably be used by pd-for-android instead; it would be better to have all android stuff moved from libpd to pd-for-android, but I think it's another story).

[joebowbeer]

@danomatika As things are now, the opensl_stream code in libpd needs to be updated:

https://github.com/libpd/libpd/tree/master/jni

Then libpd in pd-for-android can be updated
