Redesign the ondisk inode timestamps to be a simple unsigned 64-bit
counter of nanoseconds since 14 Dec 1901 (i.e. the minimum time in the
32-bit unix time epoch). This enables us to handle dates up to 2486,
which solves the y2038 problem.

Redefine xfs_ictimestamp_t as a uint64_t typedef in preparation for the
bigtime functionality. Preserve the legacy structure format so that we
can let the compiler take care of the masking and shifting.

Move this function to xfs_inode_item_recover.c since there's only one
caller of it.

Log recovery has it's own buffer write completion handler for
buffers that it directly recovers. Convert these to direct calls by
flagging these buffers as being log recovery buffers. The flag will
get cleared by the log recovery IO completion routine, so it will
never leak out of log recovery.

Call the data/attr local fork verifiers as soon as we are ready for them.
This keeps them close to the code setting up the forks, and avoids a
few branches later on. Also open code xfs_inode_verify_forks in the
only remaining caller.

We always need to fill out the fork structures when reading the inode,
so call xfs_iformat_fork from the tail of xfs_inode_from_disk.

Move the log inode item pass2 commit code into the per-item source code
files and use the dispatch function to call it. We do these one at a
time because there's a lot of code to move. No functional changes.

Create a generic dispatch structure to delegate recovery of different
log item types into various code modules. This will enable us to move
code specific to a particular log item type out of xfs_log_recover.c and
into the log item source.
The first operation we virtualize is the log item sorting.
