[PATCH 0 of 7] lguest host code

[rusty at rustcorp.com.au (Rusty Russell)]

These seven patches replace [PATCH 6/10], or in the second send, patches
6a. 6b, 6c and 6d.

There are more patches because Andi hassled me about extern decls, so I
had to expose some things.  Tiny patches, but worth separating because
you never know when such changes will break something.  Compiles and
runs here...

Thanks,
Rusty.
