EQT feature updates.
1. Improves documentation in help and x265readthedocs for rskip cli options.
2. Renamed rskip variable in x265_param structure & rectified regression
clis.
3. Removed rskip mode 3 which is same as mode 2 with min-cu-size 16.

EQT feature updates.
1. Improves documentation in help and x265readthedocs for rskip cli options.
2. Renamed rskip variable in x265_param structure & rectified regression
clis.
3. Removed rskip mode 3 which is same as mode 2 with min-cu-size 16.
