Final patch ----------- This WL is about using this bitmap in all parts of the partition handler. Thus for: rnd_init/rnd_next index_init/index_next and all other variants of index scans read_range_... the various range scans implemented in the partition handler. Also use those bitmaps in the various other calls that currently loop over all partitions.

- Added more comments. - Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables construction of index_merge SEL_TREEs that represent unusable conditions like "key1part1<c1 OR key2part2<c2" - make prune_partitions() function handle the case where range analysis produces a list of index_merge trees (it turned out that this is possible, appropriate test case added). - Other small fixes.
