Applied innodb-5.0-ss660 snapshot. 


innobase/btr/btr0cur.c:
  Applied innodb-5.0-ss660 snapshot.
   btr_cur_search_to_nth_level(): Reacquire btr_search_latch after
   inserting to the insert buffer. This was noticed while analyzing
   Bug#19081 but this shold not fix this bug since according to
   Heikki, btr_search_latch is not reserved during an insert.
innobase/ibuf/ibuf0ibuf.c:
  Applied innodb-5.0-ss660 snapshot.
   ibuf_fixed_addr_page(): Add parameter space. As the insert buffer
   B-tree is only located in the system tablespace (space 0),
   IBUF_TREE_ROOT_PAGE_NO is only special in space 0.
innobase/include/sync0rw.ic:
  Applied innodb-5.0-ss660 snapshot.
   rw_lock_s_unlock_func(): Change a debug assertion to a
   production assertion in order to track down Bug#19081.
