Currently, we are using chattr/lsattr for project quota
interface, this have some problems:

1)Client side need patched e2fsprogs or latest upstream e2fsprogs.
2)Project quota will be no longer osd-ldiskfs based, ZFS
too, zfs guys might dislike ldiskfs tool dependency for them.
3)customers argue chattr might be a little dangerous.

So this patch add native lfs tools for project quota.
usage: project [-p id] [-s] [-r] <file|directory..>
          set project ID and/or inherit flag for specified
          file(s) or directory.
       project [-d|-r [-0]] <file|directory...>
          list project ID and flags on file(s) or directory,
          print outliers
       project -c [-d|-r [-p id] [-0]] <file|directory..>
          check project ID and flags on file(s) or directory,
          print outliers
       project -C [-r] [-k] <file|directory..>
          clear the project inherit flag and ID on the file
          or directory
