meta: make return codes more generic
ST/DE/HD all mean "okay". EX/NF/etc are already reused.
VA has different response parsing. EN/MN are specific.
future commands should be able to reuse most of these. In the odd case
new ones are added, clients would have to be updated. Generally they
shouldn't have to be.
