3f1c4ba745 handler interface cleanups: 
more logical table/index_flags
  return  HA_ERR_WRONG_COMMAND instead of abstract methods where appropriate
  max_keys and other limits renamed to max_supported_keys/etc
  max_keys/etc are now wrappers to max_supported_keys/etc 
  ha_index_init/ha_rnd_init/ha_index_end/ha_rnd_end are now wrappers to real {index,rnd}_{init,end} to enforce strict pairing

f874071a26 Range optimizer fix: 
If cost(full_scan_on_shortest_covering_index) < cost(best_range_scan) <  cost(full_table_scan)
  use full_scan_on_shortest_covering_index
(before this fix best_range_scan was used)

f207b33a7b Support for character set conversion in binary protocol: another go 
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
  connection on the fly, because they first should be written to the binary
  log.
  To support efficient conversion we need to rewrite prepared statements
  binlogging code first.

a46d7542c9 This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys" 
The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.
