This series removes the use of udev rules to call hotplug scripts when 
using libxl. Scripts are directly called from the toolstack at the 
necessary points, making use of the new event library and it's fork 

They should be applied after IanJ v8 "libxl: subprocess handling" and 
IanC "libxl/xend: name tap devices vifX.Y-emu".

This version (v4) introduces many changes, and makes proper use of the 
event library. It entangles device addition with domain creation, 
following IanJ changes to domain creation, and also introduces AO 
operations to domain destruction and specifically to device teardown.

Many changes are introduced, and also a lot of code motion, since 
libxl_device_{disk,nic}_add are now mere wrappers arround their 
respective libxl__device_{disk,nic}_add counterparts, which can be 
called within an already running AO operation, and perform all the
