Remove the printing of fragment fields that are HURD only, and
instead print the i_checksum_lo and i_checksum_hi fields.
Allow setting newer fields in extra inode space with modify_inode.
Add inode_includes() macro to simplify checking for fields in the
large inode, rather than hard-coding field offsets in the code.
Fix corresponding tests for newly added Checksum field.
