[PATCH v9 00/15] execute hotplug scripts from libxl

[Roger Pau Monne <roger.pau@citrix.com>]

This series have been splitted into several patches, to make them 
easier to review. Also the amount of changes introduced is quite 
important, since apart from all the hotplug necessary functions and
modifications, libxl_domain_destroy has been converted to an async op.
This was necessary in order to have async operations during device
removal.

Also, as an important change, disk and nics are added at different
points for HVM and device model based guests, since we need the disk
in order to start Qemu, but the nic hotplug scripts should be called
at a later point, when Qemu has created the corresponding tap device.

This version includes changes requested by Ian Campbell, and two new 
patches that convert vkb and vfb to async functions. Also since Qdisk, 
vfb and vkb don't follow the disconnection protocol (probably because 
Qemu is already dead when that happens), we don't wait for them to 
reach state "closed", and just clean the relevant xenstore entries.
