Oboe support (#167)
* update libpd to oboe branch, and link PdCore with oboe library * add new input/output audio device settings to preferences and audio logic * update demo apps for oboe changes - add MODIFY_AUDIO_SETTINGS permission, which oboe needs to give best results - add "APP_STL := c++_shared" to Application.mk when the app needs native compilation * bump version to 1.4.0
