      - Make the range-et-al optimizer produce E(#table records after table 
                                                 condition is applied),
      - Make the join optimizer use this value,

      WL# 2986 · 437368e4
      patg@govinda.patg.net authored
      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.

      sergefp@mysql.com authored
      - post-...-post review fixes
      - Added "integer range walking" that allows to do partition pruning for "a <=? t.field <=? b"
        by finding used partitions for a, a+1, a+2, ..., b-1, b.
