adds support for a portable db import/export format (closes: #1521112)
the db-dump and db-restore cwctl commands are enhanced with a --format option
(defaults to 'native'). If the format is 'portable', then the system database
dump / restore is performed using pure SQL queries and the storage uses picked
Python objects in a zip archive.
/* -*- sql -*-
mysql specific registered procedures,

/* XXX limit_size version dealing with format as postgres version does.
XXX mysql doesn't support overloading, each function should have a different name
NOTE: fulltext renamed since it cause a mysql name conflict
*/
CREATE FUNCTION text_limit_size(vfulltext TEXT, maxsize INT)

BEGIN
IF LENGTH(vfulltext) < maxsize THEN
RETURN vfulltext;
ELSE
RETURN SUBSTRING(vfulltext from 1 for maxsize) || '...';
