[libvirt] [PATCH v3 00/13] Implement alternative metadata locking

v3 of: https://www.redhat.com/archives/libvir-list/2018-October/msg00667.html diff to v2: - Introduced two new patches (1/13 and 2/13) so that even non-Linux platforms are covered - In 4/13 I switched from indefinite wait for lock to a lock with timeout (of 10 seconds). This is basically to prevent us stalling if some app misbehaves and holds the file locked for eternity.
