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.

Keir Fraser 5991224aff minios: fix and enforce block_domain atomicity 
To ensure that the timer event is not lost, block_domain requires that
event delivery is disabled.  SCHEDOP_block re-enables them, so for
coherency (and fixing a bug actually), we should re-disable them
after. Also, make sure that the caller disabled them.
