The old code was case-insensitive,

the new code is not.  Do we care?  (I don't, but we could be breaking
someone's control flow).  Should qapi_enum_parse be taught to be
case-insensitive?  Or perhaps we answer related questions first: Do we
have any QAPI enums that have values differing only in case? Do we
prevent such QAPI definitions, to give us the potential of making the
parsing insensitive?
