This patchset adds QEMU support for querying fd-based KVM stats. The
kernel support was introduced by:

cb082bfab59a ("KVM: stats: Add fd-based API to read binary stats data")

v4:
- revise and cleanup the API [Daniel, Paolo]
- filtering for multiple providers [Daniel]
- cache KVM stat descriptors [Paolo]
- use g_autofree and other cleanup [Daniel]

v3:
- various QMP API enhancements from review [Daniel, Paolo, Igor]
- general cleanup

v2: [Paolo]
- generalize the interface
- add support for querying stat schema and instances
- add additional HMP semantic processing for a few exponent/unit
  combinations (related to seconds and bytes)
