PDOS now does Win64

[Paul Edwards]

It turns out (forest for the trees) that there is not very
much "glue" required to convert the EFI OS into a
(basic) Win64 OS.

So University Challenge x64 (UCX64) available from
http://pdos.org is now able to run a subset of Win64
executables.

Much larger subset now, including a nearly-C90-compliant
public domain C compiler. :-)

There are some caveats, like control keys not being
recognized on real hardware. Still working through what
appears to be largely cosmetic stuff remaining.
