fe03f6bbe0 Bug #27531: 5.1 part of the fix
- Renamed "Using join cache" to "Using join buffer".
- "Using join buffer" is now printed on the last
  table that "reads" from the join buffer cache.

306371a850 bug #27531: 5.1 part of the fix:
- added join cache indication in EXPLAIN (Extra column).
 - prefer filesort over full scan over 
   index for ORDER BY (because it's faster).
 - when switching from REF to RANGE because
   RANGE uses longer key turn off sort on
   the head table only as the resulting 
   RANGE access is a candidate for join cache
   and we don't want to disable it by sorting
   on the first table only.

699291a8e6 BUG#14940 "MySQL choose wrong index", v.2
- Make the range-et-al optimizer produce E(#table records after table 
                                           condition is applied),
- Make the join optimizer use this value,
- Add "filtered" column to EXPLAIN EXTENDED to show 
  fraction of records left after table condition is applied
- Adjust test results, add comments
