Make libhwbinder build.

- Moved Android.mk to root
- Changed module name to libhwbinder
- Updated all references to include/binder to include/hwbinder
- Removed services that we know will certainly not exist in hwbinder:
  * AppOps
  * BatteryStats
  * MediaResourceMonitor
  * ProcessInfoService
  * PermissionCache
- Removed tests (we'll have new ones).
