This is done by adding the general ability to stuff non-SUSP data into
the end of the System Use field of a Directory Record, which required
some amount of rewriting of the SUSP support. I think the result is
at least as good as what came before, and I've fixed at least one bug
along the way. Tested against RISC OS 3.70 on my Risc PC.
Oh, why do we want it? It should allow us to make acorn{26,32} CDs that
can be booted directly from RISC OS without mucking around copying the
bootloader to a native filing system.
