Android: Refactor some of the glue code.

Browse source 
* Cleanup RockboxService.java by moving the battery and
  headphone monitors to separate classes and detaching their instances
* Move those monitors and RockboxTelephony.java into a new
  monitors subdirectory
* Call those monitors all the same from native code by creating
  the objects there
