* INetwork setOwnAircraft slots
* ATIS received shimlib callback triggers separate VoiceRoom and LogoffTime signals
* INetwork statusMessage signal emitted in response to shimlib errors
* INetwork::ConnectionStatus added a DisconnectedError value and toString conversion
* INetwork::isConnected method
* Argument in CNetworkVatlib constructor to enable stealth or observer mode
* Update CLI sample, tests, and CContextNetwork accordingly
as we have it now in INetwork. The connection state
from the shimblib should not be used in the client
code (abstraction from "drivers"), and in the past the
corresponding client state was declared here, but is now
one level deeper in INetwork.
A second change applied here is to use the signature
connectionStatusChanged(from, to), which allows the GUI
to better detect whether we login or logout without keeping
its own state.
* rename CStatusMessages to CStatusMessageList
* rename NetworkVatlib to CNetworkVatlib
* replace all occurrences of Realname with RealName (correct camel case)
* CSequence method corresponding to CList::append is push_back
* don't compile the qdbuscpp2xml metadata plugin by default
* CAircraftIcao string members always trimmed and capitalized
* added CComSystem::roundTo25KHz
* using epsilon comparison in a couple of places
