Keir Fraser ae41a026ab minios: grant table map (gntdev) bug fixes 
* Uninitialized dev_bus_addr argument to GNTTABOP_unmap_grant_ref
   results in an angry hypervisor.
 * Set errno in libxc and return -1 on error.
 * op.status is a int16_t, so it should be printed with PRId16.
 * Don't print domids[0] or refs[0] if the ptr is NULL. It's more
   polite to crash later, after the message has been printed.

I've implemented a grant map for mini-os to support the xc_gnttab_*()
functions, the equivalent of gntdev in linux. This is useful for my
work in putting xenstored in a stub domain.

Keir Fraser 8f96998338 stubdom: fixes to compile with qemu-xen 
This adds fixes to the stub domain build into compiling Ian Jackson's
qemu-xen.  The most notable change is that mini-os headers now
#include each other through a mini-os/ prefix, so that we can turn all
-I into -isystem and still be sure that we include Mini-OS headers
(and not qemu's console.h or blktaplib's list.h for instance...).

Keir Fraser a2c7db64f5 Add PV-GRUB 
This fetches GRUB1 sources, applies the {graphical, print function,
save default, and ext3_256byte} patches from debian, and applies a
patch to make it work on x86_64 and port it to Mini-OS.  By using
libxc, PV-GRUB can then "kexec" the loaded kernel from inside the
domain itself, hence permitting to avoid the security-concerned
pygrub.
