BLE Update (#84)

Fix #80 by handling CCCD for all characteristics

Some BLE implementation requires the presence of CCCD(Client Characteristic Configuration Descriptor) to propery "subscribe" to notifications and indications.

By default we allow notification/indication of all characteristics, so we add CCCD to all characteristics and corresponding read/write callbacks.

Note that this increases the callback table usage, since 1 characteristics now requires 2 callback functions. Therefore, the number of statically allocated callback table is doubled from 30 to 60 entires.

* Fix #82 by fixing UUID comparison between 16-bit and 128-bit UUIDs

In some cases where both 16-bit UUID and 128-bit UUID characteristics present, the implementation of UUID comparison is incorrect. This leads to incorrect retrieval of the characteristic GATT database handles. Therefore the remote peripheral device won't be able to update the correct characteristics. 

* Re-format files

* TxPower should be signed

* Add LBLE keywords

* Fix build warnings
