This patchset adds support for cgroup management of ch threads. This version
correctly manages cgroups for vcpu and emulator threads created by ch. cgroup
management for iothreads is not yet supported.

Along with cgroup management, this patchset also enables support for pinning
vcpu and emulator threads to selected host cpus.

v3:
* addrressed all the formatting comments in v2 patch set
* dropped indentation patches are they do not adhere to libvirt coding style
* fixed build issue in qemu driver that was introduced in v2

  util: Helper functions to get process info
  ch_driver,ch_domain: vcpu info getter callbacks
  qemu,hypervisor: refactor some cgroup mgmt methods
  ch_process: Setup emulator and iothread settings
  ch_driver: emulator threadinfo & pinning callbacks

Vineeth Pillai (8):
  ch_domain: add virCHDomainGetMonitor helper method
  ch_domain: add methods to manage private vcpu data
  ch_driver: domainGetVcpuPinInfo and nodeGetCPUMap
  ch_monitor: Get nicindexes in prep for cgroup mgmt
  ch: methods for cgroup mgmt in ch driver
  ch_driver,ch_domain: vcpupin callback in ch driver
  ch_driver: enable typed param string for numatune
  ch_driver: add numatune callbacks for CH driver
