Direct-BT: Remove TinyB and Cleanup Java API (1)
Starting with version 2.3, the previously refactored *TinyB* has been removed completely. Motivation was lack of detailed Bluetooth support, inclusive increasing diversion with *Direct-BT*. Furthermore, work is underway for `BLE slave periphal and GATT server` support and its mapping to *BlueZ D-Bus* is questionable and would be resource intensive. Java API changed as follows: - Objects no more Clonable - Removed dead unsupported code - Removed deprecated code - Added 'GattCharPropertySet', representing property bit mask for BTGattChar, replacing the string array.
