[libvirt] [PATCH 0/4] bulk stats: QEMU implementation polishing

This patchset does polishing on the QEMU bulk stats implementation. The main issue this patchset addresses is that, unless a critical error is found, bulk stats should be silent and ignore errors. To do so, virResetLastError() is used in a few places, but this is not enough since errors are logged anyway. A better approach is to avoid to report error entirely. The patchset is organized as follows: - patches 1 to 3 enhances the functions used in the bulk stats path(s) adding a 'bool report' flag, to let the caller optionally suppress error reporting. - patch 4 is a general polishing patch which reduces repetition of the code in the block stats collection.
