ZF-2028: Docblock for Zend_Db_Adapter_Abstract::setFetchMode() specifies neither return type nor any exceptions thrown

Description

What happens if you give {{Zend_Db_Adapter_Abstract::setFetchMode()}} an invalid value? The docblock specifies neither the return type nor any exceptions thrown.

Comments

Added @throws to Abstract and to subclasses with SVN-8080. There is no returned value therefor void is the right declaration.
