- Modifies the way indexed UPDATE/DELETE are sorted in order to execute

Browse source 
them sorted by file position. Firstly a new value is stored in indexes
  to know if they are sorted, preventing to do the sorting when it is not
  needed. Secondly, almost all in now done in connect instead of being
  done by the different file access method classes. This pepares the future
  use of temporary files for all table types and also fix the bug that was
  occuring when partially using a multi-column index because of false MRR
  like call of position followed by unsorted rnd_pos no more using indexing.
