      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.
      
      
      
      
      mysql-test/r/partition_pruning.result:
        WL# 2986
        
        New results reflecting bitmap being used to determine if a partition is to be
        included
      mysql-test/t/partition_pruning.test:
        WL# 2986
        
        New tests to show bitmap being used in ha_partition
      sql/ha_partition.cc:
        WL# 2986
        
        Used work from 2682 and removed the partition select code.
            
        Added do {} while loop to any iteration over partitions to now utilise 
        m_part_info->used_partitions bitmap to determine if a partition should be
        used.
      sql/ha_partition.h:
        WL# 2986
        
        Removed unused member
      sql/handler.h:
        WL# 2986
        
        Removed unused member
      sql/opt_range.cc:
        WL# 2986
        
        Added bitmap_clear_all to clear bitmap prior to pruning
        DBUG code for testing
      sql/sql_partition.cc:
        WL# 2986
        
        Changed < to <=, which fixes the problem with edge cases going awry.
