Needs 'Since: 2.1'.

Not your fault, as the problem already exists, but it's a bit awkward
that qapi-event.json is not self-contained, and your patch is only
making it worse.  qapi-event.json only makes sense when included by
qapi-schema.json, when ideally it would be nice if it made sense if
compiled in isolation. I already pointed this fact out on Wenchao's
series that made events part of QAPI, but fixing it first requires
teaching the code generators to flag places where a type is used without
a pre-definition, so that we know which types have to be moved into a
common include.  So don't let this comment hold up your patch.

If you add the Since line,
