Applied innodb-5.0-ss368 snapshot

  Fixed bugs:
  #16814: SHOW INNODB STATUS format error in LATEST FOREIGN KEY ERROR section
    dict_foreign_key_error_report(): Always print a newline after invoking
    dict_print_info_on_foreign_key_in_create_format().
  #16827: Better InnoDB error message if ibdata files omitted from my.cnf.
  #17126: CHECK TABLE on InnoDB causes a short hang during check of adaptive hash.
    CHECK TABLE blocking other queries, by releasing the btr_search_latch
    periodically during the adaptive hash table validation.
  #17405: Valgrind: conditional jump or move depends on uninitialised valuesw.
    buf_block_init(): Reset magic_n, buf_fix_count, and io_fix to avoid testing
    uninitialised variables.
  #18077: InnoDB uses full explicit table locks in stored FUNCTION.
  #18238: When locks exhaust the buffer pool, InnoDB does not roll back the trx.
    Check in pessimistic insert and update if the buffer pool is exhausted by locks.
  #18252: Disk space leaks in updates of InnoDB BLOB rows.
    btr_cur_pessimistic_update(): Invoke rec_get_offset() after rec_set_field_extern_bits().
    btr_store_big_rec_extern_fields(): Note that offsets will no longer be valid
    after calling this function.
  #18283: When InnoDB returns error 'lock table full', MySQL can write to binlog too much.
  #18384: InnoDB memory leak on duplicate key errors if row has many columns.
    row_ins_duplicate_error_in_clust(): Call mem_heap_free(heap) at func_exit if needed.
  #18350: Use consistent read in CREATE ... SELECT .. if innodb_locks_unsafe_for_binlog is used.
