Yes, this is an improvement over the current code. But it doesn't move
in the direction we (or better Anthony) originally had for events in
the QAPI.
Basically, *iirc*, the idea was to have an event type, so that we could
declare events as:
{ 'event': 'BLOCK_IO_ERROR', 'data': { 'device': 'str',
'operation': 'str',
'action': 'str' } }
(Note that keys 'operation' and 'action' should be enums)
Then the QAPI could generate C functions to register and de-register from
an event. This way C code could benefit from events too, and we could
also allow QMP clients to register/de-register to/from events.
Maybe we could apply this series as a first step, but I can't tell if
later on we'll regret it due to compatibility issues or if we'll realize
it was unneeded churn.
