Floris Bruynooghe c8d296ea0e A MsgId newtype
This more strongly types the ubiquitous message id type by no longer
making it an integer.  It keeps the actual ID opaque.  Only for the
generic job API the number keeps being used.  Some locations also need
to create it from an integer and call MsgId::new().
