New code for 6.5:

 * Fix a problem where shrink would blow out the space reserve by
   declining to shrink the filesystem.
 * Drop the EXPERIMENTAL tag for the large extent counts feature.
 * Set FMODE_CAN_ODIRECT and get rid of an address space op.
 * Fix an AG count overflow bug in growfs if the new device size is
   redonkulously large.
