{'type':'AvailAccel', 'data': {
  '*kvm': 'KvmExtraProps',
  '*tcg': 'TcgExtraProps',
  '*xen': 'XenExtraProps',
  '*hax': 'HaxExtraProps' } }
{'command':'query-accel', 'returns': {
   'available': 'AvailAccel', 'active': 'strOrEnum' } }

where adding a new accelerator then adds a new optional member to
AvailAccel as well as possibly a new enum member if 'active' is driving
by an enum instead of 'str'.
