Implement libpayload support and improve life for DOS based flashrom, too
Corresponding to flashrom svn r1181.
Change the physmap* behaviour to use (void*)-1 as error code instead
of NULL. That way, 1:1 mapped memory can be supported properly
because (void*)0 is not a magic pointer anymore.
(void*)-1 on the other hand is a rather unlikely memory offset, so that
should be safe.
