  branches/5.1: Undo the change from r6424. We need to return DB_SUCCESS even
  if we were unable to initialize the tabe autoinc value. This is required for
  the open to succeed. The only condition we currently treat as a hard error
  is if the autoinc field instance passed in by MySQL is NULL.

  Previously if the table autoinc value was 0 and the next value was requested
  we had an assertion that would fail. Change that assertion and treat a value
  of 0 to mean that the autoinc system is unavailable. Generation of next
  value will now return failure.

  branches/5.1: Check *first_value everytime against the column max
  value and  set *first_value to next autoinc if it's > col max value.
  ie.  not rely on what is passed in from MySQL.
