[libvirt] [PATCH v2 0/5] Add read error ignore to storage backend vol info APIs

v1 took a simplistic approach: http://www.redhat.com/archives/libvir-list/2015-October/msg00919.html but not specific enough according to the review. So adding some extra complexity of checking for specific errors and flag bits to "ignore" the error similar to the catch-all openflags VIR_STORAGE_VOL_OPEN_NOERROR for all the virStorageBackendUpdateVol{Info|TargetInfo|TargetInfoFD} API's which are used to get the volume capacity, allocation, etc. data. Along the way an inavertent bug was found and fixed in patch 3 in virStorageBackendUpdateVolTargetInfo where an error could have been reported, but not propagated back to the user since 'ret' would have been 0 after the virStorageBackendUpdateVolTargetInfoFD call.
