bd14136331 ha_innodb.cc: 
Fix bug: MySQL could erroneously return Empty set if InnoDB estimated index range size to 0 records though the range was not empty; MySQL also failed to do the next-key locking in the case of an empty index range

14749b89bb ha_innodb.cc: 
Remove (already commented out) code about storing the latest relay log pos info to InnoDB: we will probably use only the master log pos info when we restart a slave after a crash

InnoDB maps HA_READ_PREFIX_LAST_OR_PREV to PAGE_CUR_LE, but note that only complete-field prefixes of the kay value can be used as the search key

e690ea09f7 page0cur.c: 
Prepare for 5.x where HA_READ_PREFIX_LAST may pass only a few first bytes of the last field in a key value
ha_innodb.cc:
  In 4.0 always assume HA_READ_PREFIX_LAST passes a complete-field prefix of a key value; LIKE queries use a padding trick

bd8c8522dc ha_innodb.cc: 
Since MySQL uses HA_READ_PREFIX_LAST in a wrong place, we make InnoDB to convert it to a right search condition

a2de9c66f5 ha_innodb.cc: 
Fix potential bug: if MySQL calls store_lock with the TL_IGNORE argument in the middle of query processing, then InnoDB select_lock_type could be reset to LOCK_NONE in a wrong place

Added optimisation for ORDER BY NULL

8e6a4c6201 ut0mem.c, row0sel.c, row0mysql.c, ut0mem.h, row0sel.h, row0mysql.h: 
Test allocation of memory beforehand if we are trying to return a > 2 MB BLOB; normally InnoDB asserts if memory allocation fails
ha_innodb.cc:
  Do not fetch all columns if change_active_index() is called during a query; a sum(a), max(a) query seemed to do that, doing unnecessary copying (the change actually made in the previous bk ci)
  Free BLOB heap of handle when MySQL calls some ::extra()'s

3ca695ea0b Cut hostnames at HOSTNAME_LENGTH to avoid theoretical hostname overruns 
Changed long packat handling to check for packets of length 0xffffff.
This does however break packet handling for older clients.
If you are using packets >= 16M then you need to upgrade client and server
after this patch.
