Adding multi_range_read support to partitions

Other things:
- Cleanup of allocated bitmaps done in open(), which
  simplifies init_partition_bitmaps()
- Add needed defines in ha_spider.cc to enable new spider code
- Fixed some DBUG_PRINT() to be consistent with normal code
- Removed end space
- The changes in test cases partition_innodb, partition_range,
  partition_pruning etc are becasue partitions can now more exactly
  calculate the number of rows in a range.

Contains spider patches:
