Detailed Description

Scanning class for cards that support a SignalMonitor class.

With ScanStreamData, we call ScanTransport() on each transport and frequency offset in the list of transports. This list is created from a FrequencyTable object.

Each ScanTransport() call resets the ScanStreamData and the SignalMonitor, then tunes to a new frequency and notes the tuning time in the "timer" QTime object.

HandleActiveScan is called every time through the event loop and is what calls ScanTransport(), as well as checking when the current time is "timeoutTune" or "channelTimeout" milliseconds ahead of "timer". When the "timeoutTune" is exceeded we check to see if we have a signal lock on the channel, if we don't we check the next transport. When the larger "channelTimeout" is exceeded we do nothing unless "waitingForTables" is still true,

This is used by DVB to scan for channels we are told about from other channels.
