[Xen-devel] [RFC Patch v4 0/8] Prepare patches for COLO

This patchset is not for xen-4.5, so I will stop to update
it until xen 4.5 is released.

To implement COLO, we introduce or update some current
APIs. These patches are independent patches, and post
them in separate series.

This patchset are also hosted on github:

  Refactor domain_suspend_callback_common()
  tools: libxl: introduce a new API libxl__domain_restore() to read qemu
  Update libxl__domain_suspend_common_switch_qemu_logdirty() for colo
  Introduce a new internal API libxl__domain_unpause()
  Update libxl__domain_unpause() to support qemu-xen
  support to resume uncooperative HVM guests
  update datecopier to support sending data only
