Input docsis_scan

The input docsis_scan will scan for DOCSIS streams in the whole frequency plan. By default, the input will only look at the standard frequency plan. If you have a ATSC/QAM card, it will use the american frequency plan. If you have a DVB-C card, it will use the european frequency plan.
To speed things up, the scan will start at a frequency most likely to contain a DOCSIS stream and will continue at the begining of the spectrum afterwards.
