Structure cleanup
This MR removes ~600 lines of unused code related to RQT.
Tests so far were bit exact except for a removed SPS extension flag.
I would suggest merging after the 3.0 release.
Changes:
- remove QTBT as config parameter
- remove related code that could not be reached when QTBT=1 was set
- remove PartSize type and code that was associated with non SIZE_2NX2N setting
The MR is split into several commits for logical separation.
