connection which did write/mkdir/rm/setperm etc.
This causes deadlocks in real life, and I can't see a sane way
of avoiding them: it is reasonable for someone to ignore watch
notifications while doing other actions, and that means that
we can do other writes. These writes can block pending other
watchers; if one of these is the process blocked awaiting our
ack, we deadlock.

to block)
Instead of using return value, use explicit state member inside

Also ensure that daemon re-xmits event if they ack wrong thing
(otherwise confused clients get stuck, as we will send no more
data while awaiting ack).

active at startup; this works by adding a module line into the grub
configuration file and placing the binary policy generated by the
policy tool into the boot directory; This assumes that a maximum of
one module line is used for the initrd in the grub configuration
file - Question: do users pass more than one module to the kernel?
- enables the policy hypervisor call on x86/64
- some function prototypes moved to include files
- moves the version number in the java tool up to the current
version (a better way of doing this will be submitted soon)

operation allows retrieval of the domain info structures for all domains
in one hypercall.
Using a small test program, on a system with 97 domains with
non-contiguous domain IDs, I found that with this hypercall I could
retrieve the full array of info structures 12840 times per second, an
improvement from 2380 times per second with the DOM0_GETDOMAININFO op.
The patch also adds a libxc wrapper for this new hypercall.
