Add a preference for changing the default CPU mode/model. The options are:
- default (whatever virt-manager chooses as the default)
- hypervisor default (no <cpu> block, what we've always done)
- nearest host cpu model (just the 'model' from caps->host->cpu)
- copy host cpu (the entire <cpu> block from caps->host)
The setting only applies to KVM guests, not tested with anything else.
The default is left as is for now (hypervisor default).
copy host CPU will one day use mode='host-model', when it does what
we want. At that point we will probably make it the default
Similar to how we allow disabling disk/net polling, not sure yet what
effect it might have on remote connections, so best to add this option
just to be safe.
Unlike disk/net stats, we enable this checking by default.
Remote sound works fine these days. If people want to turn the
preference off, they probably want to do it in all cases, and can
'customize before install' to alter the rest.
This unfortunately has a decent amount of fallout: add a wrapper class
in config.py that reduces much of the churn.
Another big piece is that gsettings can't accept arbitrary paths like
gconf would, everything needs to be described in the schema.
Also do a bunch more RPM spec modernizing
Despite being a known quantity, autotools is so overkill for our needs,
so let's drop it and replace it with a much simpler and easy to customize
system.
