bug#3593869-64035

Browse Source 
A follow-up patch corrects max sizes of printed strings and changes llstr() to %lld.
Credits go to Davi who provided a great feedback.


sql/share/errmsg-utf8.txt:
  Max size for the whole message is 512 so a part of - like '%-.512s' should be less,
  reduction to 320 is safe and with good chances won't cut off a part of a rather log
  message in Last_IO_Error = 'Got fatal error 1236 ...'
sql/sql_repl.cc:
  llstr() is replaced by %lld.
