[v2,0/3] : generic/020: fix MAX_ATTRVAL_SIZE values

Message

MAX_ATTRVAL_SIZE provides a per-filesystem maximum xattr value length
limit. There are a few problems with the current values:
- XFS, UDF and Btrfs are incorrectly hardcoded to use 64 bytes
  + This is a regression from the larger value used prior to fff4359d
  + Btrfs's should be calculated using nodesize and xattr name length
- NFS currently uses a 64K limit
  + This may be above the server's underlying failsystem limit, so use
    a conservative estimate instead

Cheers, David
