  Fix some too small buffers in backup
  

    Fix bug in restore with table with many columns, Compute size of databuffer pool correctly

    Add better error message if getting error in RESTORE

    when doing create unique index which mysql will silently converts to PK, ndb is not informed
    so table will be useless.
  
    change so that we never do online add index wo/ primary key.
    this is not good, but it's better than a useless table

Early abort, failing to allocate buffers, would go down the abort track and
 end up trying to sendDropTriggers (as the standard stop backup does). 
However, it is possible to not have any tables yet defined in the backup 
(due to allocating buffers is before this). Simple check in sendDropTrig 
(and continue to next step). Files may be open, so we continue to close them.

Also updated ERROR_Codes (and added one to test this bug).
