Hibernation: Correct definitions of some ioctls (rev. 2)

Three ioctl numbers belonging to the hibernation userland interface,
SNAPSHOT_ATOMIC_SNAPSHOT, SNAPSHOT_AVAIL_SWAP, SNAPSHOT_GET_SWAP_PAGE,
are defined in a wrong way (eg. not portable).  Provide new ioctl numbers for
these ioctls and mark the existing ones as deprecated.
