MLRsearch: Support other than just two ratios
+ Change some method names and argument types: + Do not mention NDR and PDR, except as examples. + Return list of ReceiveRateInterval instead of NdrPdrResult. + The resulting intervals can be degenerate when hitting min/max rate. + Rename quantity name parts from "fraction" to "ratio". + Intervals are no longer tracked for each target ratio. + They are found dynamically from known results. + Add effective_loss_ratio field to avoid loss inversion effects. + Move some functions to separate files. + Bound search logic moved to MeasurementDatabase.py + ProgressState moved to its file. + WidthArithmetics.py holds small computation functions. + Use parameter expansion_coefficient instead of "doublings". + Do uneven bisect to save time when width is not power of two times goal. + Timeout now correctly tracked for the whole search, not just the current phase. + Make logging (debug) function pluggable. + Added debug log messages for initial phase. + Do not mark as subclass if contructor signature differs. + Avoid re-measure on scale-limited (ASTF) profiles. + Remove outdated comments. + Bump copyright years.
