a7a1d4dc1e Fix for BUG#10244: 
Make get_quick_select_for_ref() accept estimated # records as parameter and 
set QUICK_RANGE_SELECT::records, as this value is used to allocate buffers 
in Multi-Range Read.

838eaec709 Fix and testcase for BUG#4984 
The crash is eliminated but still it is weird/inefficent that ROR-intersection is used when performing updates in empty table.

Note: The following tests fails

Sanja needs to check out the calling of close_thread_tables() in sp_head.cc

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

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.
