[libvirt] [PATCHv3 0/4] Use nodeGetCPUCount/virNodeGetCPUMap where appropriate

[Viktor Mihajlovski]

This series concludes the introduction of the virNodeGetCPUMap API
by replacing the usage of virNodeGetInfo for computing the maximum number
of node CPUs with either nodeGetCPUCount or virNodeGetCPUMap.

It's basically a resend of the original 3-patch series plus the
nodeGetCPUCount fix. Event in the light of Peter Krempa's recent
CPU topology fix this series is still relevant.

1/4 is needed to support older kernels
2/4 is not strictly required but is more efficient
3/4 and 4/4 are required for correct function of vcpu pinning calls
of python and virsh clients when talking to libvirtd 1.0.0.

V3 Changes:
- pulled in the nodeGetCPUCount patch for older kernels
- changed commit message of 2/4

V2 Changes:
Rework based on Eric's feedback:
- Use nodeGetCPUCount instead of nodeGetCPUMap
- Avoid code bloat by computing node CPU count in a helper function

Viktor Mihajlovski (4):
  nodeinfo: enable nodeGetCPUCount for older kernels
  qemu, lxc: Change host CPU number detection logic.
  python: Use virNodeGetCPUMap where possible
  virsh: Use virNodeGetCPUMap if possible
