[RFC,0/4] xfstests: widen timestamps to deal with y2038

Hi all,

This series performs some refactoring of our timestamp and inode
encoding functions, then retrofits the timestamp union to handle
timestamps as a 64-bit nanosecond counter.  Next, it refactors the quota
grace period expiration timer code a bit before implementing bit
shifting to widen the effective counter size to 34 bits.  This enables
correct time handling on XFS through the year 2486.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
