[PATCH v2 03/19] android/bluetooth: Add possibility to register for bonded event

[Lukasz Rymanowski <lukasz.rymanowski@xxxxxxxxx>]

Some modules might be interested in fact that device has been bonded.
This patch allows to register for that event

Note that callback is called only on success bonding.
