Working GATT Java Side; GATT Types made fully functional for user to avoid 'technical' GATTHandler

GATT Types made fully functional for user to avoid 'technical' GATTHandler (C++)

> GATTService, GATTCharacteristic, GATTDescriptor

-- Reside in their own respective files

-- Added semantic methods (readValue(), ..) implemented using DBTDevice -> GATTHandler

-- GATTDescriptor owns its value

-- GATTHandler setSendIndicationConfirmation(..) defaults to true

-- Allow user to cirvumvent using GATTHandler manually completely,

       device 1--*> services 1--*> characteristics 1--*> descriptor

-- C++ GATT types aligned 1:1 to TinyB (Java)

> Merged GATTIndicationListener + GATTNotificationListener -> GATTCharacteristicListener

-- Simplifying usage, unifying notification and indication

-- Now using a list of shared_ptr<GATTCharacteristicListener> allowing multiple actors
   instead of just a one shot entry. Similar to AdapterStatusListener,
   we utilize this also on the Java side to implement the TinyB notifications.

See dbt_scanner00.cpp: Simplified high-level usage.

See dbt_scanner01.cpp: Lower-level technical usage w/ GATTHandler.

> Simplified more names

> Removed redundancy in listener callbacks,

-- don't pass adapter when device is already given.
   device <*--1> adapter

-- don't pass GATT handle explicitly when characteristic is passed

> Comparison of all GATT types are done by their respective unique handle
  Attribute handles are unique for each device (server) (BT Core Spec v5.2: Vol 3, Part F Protocol..: 3.2.2 Attribute Handle)

> GATTHandler: Own L2CAPComm instance directly, instead of shared_ptr.

> JNIMem: Added JNICriticalArray class for RAII style release

Working GATT Java Side

> All toString() methods return the C++ toString() via JNI for better representation.

> DBTDevice.java/JNI: Resolved the odd 'adapter' reference issue:
-- Was not passing the jobject of DBTAdapter, but its shared container refeference ;-)

> All GATT types receive their GATT handler for equal test and identity @ ctor

> GATT read/write Value update the cached value as well as issue the notifyValue on change,
  including GATTCharacteristic notification/indication listener
