Right now, libvirt only supports the cfq based blkio cgorup,

this means if the block devices doesn't use cfq scheduler, the

blkio cgroup will loss effect.

This patchset adds the throttle blkio cgroup support for libvirt,

intoduces four elements for domain configuration and extend the

virsh command blkiotune.

intoduces/introduces/s

This patchset is a new version of Guan Qiang's patchset

://www.redhat.com/archives/libvir-list/2013-October/msg01066.html

Change form Guan Qiang's patchset:

1, split to 8 patches, make logic more clear

2, change the type of read/write iops form unsigned long long to unsigned int,

   trying to set read/write iops to the value which bigger than max number of

   unsigned int will fail.

3, fix some logic shortage.

    virDomainBlkioDeviceParseXML

rename virBlkioDeviceWeightArrayClear to virBlkioDeviceArrayClear

rename virBlkioDeviceWeightPtr to virBlkioDevicePtr
