[XFS] Move compat ioctl structs & numbers into xfs_ioctl32.h

Browse Source 
This makes the c file less cluttered and a bit more
readable.   Consistently name the ioctl number
macros with "_32" and the compatibility stuctures
with "_compat."  Rename the helpers which simply
copy in the arg with "_copyin" for easy identification.

Finally, for a few of the existing helpers, modify them
so that they directly call the native ioctl helper
after userspace argument fixup.
