Author: Vincent Coubard
Add status parameter in terminateCharacteristicDiscovery function.
Fix terminate discovery (the replacement of the discovery was done after
the call to terminate).
When searching for a running discovery, dismiss results where the
characteristic is equal to the default characteristic value
Add Discovery::operator!=
Add support of DiscoveredCharacteristic last handle in the characteristic
discovery process
