Thanks!  I've twiddled your patch a bit and checked it in as a file in
the patches dir (for now, at least):  osx-create-time.diff

I changed the storing of the data to store the time value as 12 bytes of
binary data -- 8 for the time_t value (for future expansion) and 4 for
the nsec value (which always be 0 at present).  The name of the
attribute was changed to com.apple.crtime96 (for the moment) .  Since it
is not an official com.apple.* value, I didn't want to use a name that
Apple might choose in the future.  The name should probably go in the
rsync.* namespace, but I'd need to move the code for reading and writing
the value out of lib/sysxattrs.c into xattrs.c to do that (I believe).
I also enabled the XATTR_NOFOLLOW option for {get,set}attrlist().
