This series extends
https://listman.redhat.com/archives/libvir-list/2022-September/234197.html
to support histogram statistics. This requires adding it as a
virTypedParameterType.

[1/5]: 
  - add virHistogram as a virTypedParameterType
  - add utility functions for virHistogram

[2/5]
  - add a global feature for histograms similar to strings

[3/5]
  - add a flag for histograms similar to the one for strings to check
    compatibility for older clients.

[4/5]
  - add histogram statistics which were previously ignored in the series
    linked above

[5/5]
  - add RPC support for virHistogram

Amneesh Singh (5):
  virtypedparam: add virHistogram as a virTypedParameterType
  add a global feature for supporting virHistogram
  virtypedparams: add VIR_TYPED_PARAM_HISTOGRAM_OKAY
  qemu_driver: add histograms to the stats
  remote: add virHistogram support for RPC as a virTypedParameterType
