Add QMP command to allow management software to query for CPU information for the running host.
The data returned by the command is in the form of a dictionary of QOM properties.
This series depends on the "Add runnability info to query-cpu-definitions" series I sent 2 weeks ago.

I like that interface, I'm going to post (maybe today? :) ) a similar interface that allows to also expand other cpu models, not just the host model.
In x86 I want to avoid exposing the details of other CPU models to libvirt because the details depend on machine-type. But if it is useful for you, I believe the same "qom-properties" dict could be returned in query-cpu-definitions.
Maybe we can then decide which one makes sense for all of us. But in general, this interface is much better compared to what we had before.
Maybe both? I think it's better to have a separate interface for querying "what exactly this host supports" and another one for querying for "what happens if I use -cpu host". In the case of x86, both are equivalent, but we can't guarantee this on all architectures. -- Eduardo
