specific information. Currently the common structure base
provides the name of the accelerator, while the specific
part is empty, but each accelerator can expand it.
- 'query-accels' QMP command returns a list of @AcceleratorInfo
For example on a KVM-only build we get:
{ "execute": "query-accels" }
{
"return": [
{
"name": "qtest"
},
{
"name": "kvm"
}
]

v8:
- Include code snippet from Markus adding to machine-target.json
to be able to use enum values or union branches conditional.
- Use accel_find() on enum to be sure the accelerator is enabled
at runtime (chat with jsnow / eblake).
Hi Phil -- Unfortunately I think I am going to defer on this one until
Markus is back. I need to chat with him about the right way to design
this, since I'm also not entirely clear on it myself.
