Changes made since v1:
- Fix typos/bugs
- Import reply_feature_abort() from cec-processing.cpp
- Add functionality to choose nearest frequency
Changes made since v2:

This frequency table will allow proper testing of tuner control. There
are three frequencies per analog broadcast type and broadcast system, so
tuner increment and decrement can be tested.

Remove static from reply_feature_abort() in cec-processing.cpp so
it can be used in cec-tuner.cpp. This is maintain testing logic

Hi Flavius,
Please make sure you label your patch with sequentially increasing versions.
I think the last one was v3 and there is no v4.
