Tests for file_getattr()/file_setattr() and xfsprogs update

[Andrey Albershteyn <aalbersh@xxxxxxxxxx>]

Hi all,

This two patchsets are update to xfsprogs to utilize recently added
file_getattr() and file_setattr() syscalls.

The second patchset adds two tests to fstests, one generic one on
these syscals and second one is for XFS's original usecase for these
syscalls (projects quotas).
