[libvirt] [PATCH 0/5 v2] Support block device online resizing

[Osier Yang]

This patch series introduce new API "virDomainBlockResize" to expose
qemu monitor command "block_size", which is for resizing the a block
device while the domain is running.

The prototype for the new API is:

    int
    virDomainBlockResize (virDomainPtr dom,
                          const char *disk,
                          unsigned long long size,
                          unsigned int flags)

    * "@disk" is the absolute source path or device target shorthand of
      the block device.

    * The units for "@size" is kilobytes.

    * "@flags" is unused currently.

[PATCH 1/5] block_resize: Define the new API
[PATCH 2/5] block_resize: Wire up the remote protocol
[PATCH 3/5] block_resize: Implement qemu monitor functions
[PATCH 4/5] block_resize: Implement qemu driver method
[PATCH 5/5] block_resize: Expose the new API to virsh

v1: http://www.redhat.com/archives/libvir-list/2011-July/msg01788.html

v1 ~ v2:
    * Nearly just rebasing, with small improvements, nothing new except
      updating the API definitions to be consistent with commit 3ac26e26.
