Add API to get addresses of peers in bond table



The new API is added to the Security Manager. Its declaration is as follows:



virtual ble_error_t getAddressesFromBondTable(Gap::Whitelist_t &addresses)



The resulting Whitelist_t structure can then be used as the actual whitelist

passes to Gap::setWhitelist().



Note that for peers that have private resolvable addresses, then an address of

the same type will be returned.
