afr: auto-resolve split-brains for zero-byte files
Problems: As described in BZ 1491670, renaming hardlinks can result in data/mdata split-brain of the DHT link-to files (T files) without any mismatch of data and metadata. As described in BZ 1486063, for a zero-byte file with only dirty bits set, arbiter brick will likely be chosen as the source brick. Fix: For zero byte files in split-brain, pick first brick as a) data source if file size is zero on all bricks. b) metadata source if metadata is the same on all bricks In arbiter case, if file size is zero on all bricks and there are no pending afr xattrs, pick 1st brick as data source.
