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
