added error code for failing send signal and timeout waiting for node failure

Bug #25275 SINGLE USER MODE prevents ALTER on non-ndb tables for other mysqld nodes
- correction of part 1
    add ndb_waiter option to wait for single user mode

  fix printout
  crashes testSystemRestart -n SR_UNDO

(part 1)
- add signal data
- add ref in dict on create/drop table/index

- terminate printing

ndb - 5.1.16 uint64 align for ndb_restore
(backport)

- do not call function if table has no autoincrement

- signals where sometimes sent too early when setting up subscriptions

After merge fix

Fixed test. On 32-bit machines which compile without
-DBIG_TABLES, MAX_ROWS is truncated to a 32-bit value.
Using a value below 4G is portable.

  aim is to:
  a) if set_connect_timeout called, timeout connect attempt (for retry on
  next call) after timeout period
  b) preserve existing blocking behaviour otherwise (for, e.g. mgmapi)
  
  Related to customer issue with long time deleting ndb_cluster_connection
  object. believe we're hanging on the connect(2) call until timeout (when
  we then realise we should exit the thread).
