Add 'query-events' command to QMP to query async events

Sometimes it is neccessary for an application to determine
whether a particular QMP event is available, so they can
decide whether to use compatibility code instead. This
introduces a new 'query-events' command to QMP to do just
that

{ "execute": "query-events" }
{"return": [{"name": "WAKEUP"},
            {"name": "SUSPEND"},
            {"name": "DEVICE_TRAY_MOVED"},
            {"name": "BLOCK_JOB_CANCELLED"},
            {"name": "BLOCK_JOB_COMPLETED"},
             ...snip...
            {"name": "SHUTDOWN"}]}
  • monitor.c: Turn MonitorEvent -> string conversion
    into a lookup from a static table of constant strings.
    Add impl of qmp_query_events monitor command handler
  • qapi-schema.json, qmp-commands.hx: Define contract of
    query-events command
