[libvirt] [V2 0/5] Support cache tune in libvirt



This series patches are for supportting CAT featues, which also
called cache tune in libvirt.

First to expose cache information which could be tuned in capabilites XML.
Then add new domain xml element support to add cacahe bank which will apply
on this libvirt domain.

This series patches add a util file `resctrl.c/h`, an interface to talk with
linux kernel's sys fs.

There are some TODO work such as logic of supportting l3code/l3data, expose
new public interface to get free cache information.

Some discussion about this feature support can be found from:
https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html
