Feature - Added channel INTERLOCK functionality #398

Added feature to interlock channels with the same interlock number configured to share DCD and PTT signaling.
Useful with several setup types where 2 or more channels shouldn't interfere with eachother without the need to use TXINH and (external) connections and/or circuitry to accomplish similar goals.

For example when radios and/or antennas are shared, or RX/TX more than 1 mode on a single soundcard and radio (with 'virtual Y-cable' setup) using multiple Direwolf channels.

Channels on the same INTERLOCK number configured are sharing DCD and PTT signaling internally.

New INTERLOCK parameter for config file interlocks all channels with the same interlock number configured to share DCD and PTT signaling.
Useful with several setup types where 2 or more channels shouldn't interfere with eachother. For example when radios and/or antennas are shared.
A value of delete_count + 100 seems to give issues with multiple channels and freq. offset decoding configured.
Extended to 168 for testing a max. with 3 channels and 7 offset decoders p/channel

This is an interesting idea.
I need more time to think about it.
Reopening.

While you're thinking about it, I have always wanted Direwolf to have the ability to QSY the radio to different frequencies. Hamlib support is already there so linking these features together for say a "scanner / responder" would be very interesting

Closed this due to a minor flaw in the code causing a 'stuck DCD' state. I (already) have updated code which seems to fix the spotted issue. Now testing for a couple of weeks on my setup before committing.
