LU-16634 misc: replace obsolete ioctl numbers

Renumber the OBD_IOC_BARRIER and IOC_OSC_SET_ACTIVE ioctl numbers
to use IOC type 'f' instead of 'g' and 'h', respectively.  Add
compatibility code to handle their deprecation in the future.

Move already-deprecated ioctls OBD_IOC_GETNAME_OLD, OBD_GET_VERSION,
IOC_LIBCFS_GET_NI, and IOC_LIBCFS_PING to lustre_ioctl_old.h also.
Remove other already obsolete ioctl number definitions.

Add new llapi_ioctl() and llapi_ioctl_dev() helper functions to
handle fallback of ioctl commands to older versions when needed.
