Support stored mysql procedures besides stored functions

MySQL stored procedures must be invoked by the "CALL" SQL command and
not by "SELECT". Add the convention that if the procedure name starts
with "CALL", then the issued SQL command is "CALL procedurename(args)".

The stored procedure support in MySQL automatically brings transaction
support too.
