This is in preparation for the y2038 changes for the vfs.
vfs inode timestamps overflow after 2038.
This abstracts the timestamp representation so that any logic
to convert between the struct inode timestamps and other interfaces
can be placed here.
The plan is to globally change all references to these types through
macros only. So when the actually internal representation changes,
it will be transparent everywhere outside of the macros.
The internal representation changes will support larger
timestamp range.
