New BLE GATT messaging protocol

This protocol creates a two Byte header for all GATT messages.
The procotol can:

  • cut qaul messages in chunks and reassemble the message
  • detect missing chunks and reorder them
  • send acknowledgements for received and failed packages

SYS communication from BLE connectivity module shall be called directly via callback from outside.
Libqaul calls the BLE module directly. There is no libqaul -> BLE_module channel needed anymore.

fixed qaul_id compile warning

Removed unused function from API
1. Linux is able to detect other devices
2. Other devices can detect Linux BLE advertisements
3. Linux device is able to recieve messages from other qaul devices
