[libvirt] [PATCHv6 0/6] Add virNodeGetCPUStats() API

[Minoru Usui]

Hi,

This is v6 of virNodeGetCPUTimeParameters() API. 
(This time, I rename it to virNodeGetCPUStats())
It returns cpu utilization or 
cumulative cpu time of the node from /proc/stat since node boots up.
This patch only supports linux host.

Changes
  v5->v6
    - Rename API name to virNodeGetCPUStats()
    - virsh nodecpustats subcommand returns raw/absolute cputime value by default,
      and add --percent option for printing utilization.
  v4->v5
    - Rebase latest libvirt GIT tree.
  v3->v4
    - Rebase this patch like virDomainGetMemoryParameters() from v2 patches. 
      (drop v3 patches except virsh subcommand)
    - Rename API name to virNodeGetCPUTimeParameters()
  v2->v3
    - Change user I/F. It is able to request what the user want by the @flags.
    - Minor change of virsh nodecputime I/F.
  v1->v2 
    - Change user I/F like virDomainGetMemoryStats()
    - It can return either cpu utilization or cumulative cpu time of the node
      depends on each driver.

  [v6] virNodeGetCPUStats: Define internal driver API
  [v6] virNodeGetCPUStats: Implement public API
  [v6] virNodeGetCPUStats: Implement remote protocol
  [v6] virNodeGetCPUStats: Implement virsh support
  [v6] virNodeGetCPUStats: Implement linux support
