    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.

    (cherry picked from commit 1719cffa911c5287715abfdb991bc8862f0c994e)
