[libvirt] [PATCH v3 0/5] add disk driver metadata_cache_size option

As this patch series only works with -blockdev configurations it is better to be pushed only after -blockdev is supported. Then 'news' and 'xml' patch need to be updated to have correct libvirt version. Diff from v2 [1]: ================= - move caps patch to top - add news patch - add _CAPPED to capabilitity name to distinguish from correspondent qemu capabilitiy - better option explanation in formatdomain.html - misc tests/english fixes as suggested We have come to agreement with John in mailing list to support QEMU versions which do not let use INT64_MAX as "maximum" value. But this will require changing qemuBlockStorageSourceGetFormatQcow2Props and a lot of other functions signature (which was not noticed during conversation). Thus I don't add such a functionality. Anyway the patch requires -blockdev from QEMU so we could only support single QEMU 3.0 version.
