[0/3] RFC: Cleanups and improvements to the zImage wrapper

[David Gibson]

Here is a set of three patches that make some substantial changes to
the zImage wrapper's flow of control.  These changes make things more
flexible, in order to more easily handle a wider variety of
platforms.  They also make some things clearer than previously.

I think these are fairly close to ready to merge, but they need more
testing on various platforms.  In particular, I'm not terribly whether
my changes will work correctly on old powermac platforms booting from
COFF.
