Bug#14635: Accept NEW.x as INOUT parameters to stored procedures

Browse Source 
from within triggers

Add support for passing NEW.x as INOUT and OUT parameters to stored
procedures.  Passing NEW.x as INOUT parameter requires SELECT and
UPDATE privileges on that column, and passing it as OUT parameter
requires only UPDATE privilege.
