[XFS] Use the generic xattr methods.

Use the generic set, get and removexattr methods and supply the s_xattr
array with fine-grained handlers. All XFS/Linux highlevel attr handling is
rewritten from scratch and placed into fs/xfs/linux-2.6/xfs_xattr.c so
that it's separated from the generic low-level code.
