[libvirt] [PATCH V2 0/4] libxl: support qemu's network-based block backends

xl/libxl already supports qemu's network-based block backends such as nbd and rbd. libvirt has supported configuring network disks for long time too. This series marries the two in the libxl driver and in the xl<->xml converter. Only rbd supported is added in this series. Support for other backends such as nbd and iscsi can be added as a follow-up improvement. Patch 1 is super trivial and contains no functional changes. Patch 2 changes the xl disk configuration produced by the xml->xl converter to use the formal key=value syntax described in xl-disk-configuration.txt. Patch 3 adds support for converting rbd info between xl and xml config formats. Patch 4 adds support for rbd disks in the libxl driver. In V2: Change commit msg, test, and code in patch3 to escape literal backslashes with a backslash.
