Total data length of the members of this structure. With "align (1)"
as structure definition attribute "length" equals the "sizeof" value
since the member data are then packed without padding.
Because this structure represents the LZO chunk header data
elements, "length" must equal "sizeof" in order to generate the
correct LZO chunk header by serializing an instance of this
structure. Hence "length == sizeof" is checked at ccompile-time
in write().
