[PATCH 2/4] android: Add helper functions for converting bdaddr transmitted over IPC

[Szymon Janc <szymon.janc@tieto.com>]

Android holds Bluetooth address in reverse order comparing to
bluetoothd. Add convenient functions for converting to and from that
format.

Convertion is done on daemon side to keep HAL library simple.
