Improve Characteristic descriptor discovery:



- all member of

  CharacteristicDescriptorDiscovery::DiscoveryCallbackParams_t are now

  const by default

- CharacteristicDescriptorDiscovery::TerminationCallbackParams_t now

  accept a status parameter which indicate if the operation ends properly

  or not

- Remove DiscoveredCharacteristicDescriptor declaration from

  DiscoveredCharacteristic.h file

- Add comparison operation to DiscoveredCharacteristic::Properties_t type

- Add lastHandle member to DiscoveredCharacteristic

- Add equality operator to DiscoveredCharacteristic

- make FunctionPointerWithContext call operation const, so that it mirror

  std::function and allow to call this kind of objects to be called when

  they are passed by const reference

- Add primitive operations to GattClient for dicovering characteristic

  descriptors

- Fullfil DiscoveredCharacteristic::discoverDescriptors function

  implementation
