BUG #14524

Browse Source 
Patch that fixes crashing when partition uses blackole for 
underlying tables.


mysql-test/r/partition.result:
  BUG #14524 New test result
mysql-test/t/partition.test:
  BUG #14524
  
  New test
sql/ha_partition.cc:
  BUG# 14524
  
  Added new class var m_no_locks to keep track of the absense of locks. If 
  '0', then lock_count returns 0, which keeps thr_multi_lock from crashing
  in the case of the underlying table being ha_blackhole.
sql/ha_partition.h:
  BUG #14524
  
  Added new class var m_no_locks to keep track of lock count
sql/lock.cc:
  BUG #14524
  
  DBUG PRINTs and ENTERs to make tracking the bug easier. I think these are 
  useful regardless of this bug.
sql/sql_partition.cc:
  BUG #14524
  
  Changed umlaut o to allow fixing bug 14524 using DDD (file would not display
  in DDD)
