Add native java screen recorder [1/2] (WIP)

This is based on the screenrecorder binary found in frameworks/av.
It has been converted to a native library with the necessary jni
hooks for interfacing withit via a ScreenRecorder java class.

Volume up + power chord is used to start and stop recording by
binding to the service found in the ScreenRecorder app:
