XFS_IOC_ZERO_RANGE uses struct xfs_flock64, and thus requires argument
translation for 32-bit binaries on x86.  Add the required
XFS_IOC_ZERO_RANGE_32 defined and add it to the list of commands that
require xfs_flock64 translation.

This patch adds support for 32bit project quota identifiers.

On disk format is backward compatible with 16bit projid numbers. projid
on disk is now kept in two 16bit values - di_projid_lo (which holds the
same position as old 16bit projid value) and new di_projid_hi (takes
existing padding) and converts from/to 32bit value on the fly.

xfs_admin (for existing fs), mkfs.xfs (for new fs) needs to be used
to enable PROJID32BIT support.

The recent compat patches make xfs_file.c include xfs_ioctl32.h unconditional,
which breaks the build on 32 bit systems which don't have the various compat
defintions.

Remove the include and move the defintion of xfs_file_compat_ioctl to
xfs_ioctl.h so that we can avoid including all the compat defintions in
xfs_file.c

Add a compat handler for XFS_IOC_FSSETDM_BY_HANDLE.

I haven't tested this, lacking dmapi tools to do so
(unless xfsqa magically gets this somehow?)

The args for XFS_IOC_FSGROWFSDATA and XFS_IOC_FSGROWFSRTA
have padding on the end on intel, so add arg copyin functions,
and then just call the growfs ioctl helpers.

The big hitter here was the bstat field, which contains
different sized time_t on 32 vs. 64 bit.  Add a copyin
function to translate the 32-bit arg to 64-bit, and
call the swapext ioctl helper.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
