Fix for BUG#15110: mysqldump --triggers: does not include DEFINER clause

There are two main idea of this fix:
  - introduce a common function for server and client to split user value
    (<user name>@<host name>) into user name and host name parts;
  - dump DEFINER clause in correct format in mysqldump.
