[PATCH v2 0/15] execute hotplug scripts from libxl

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

This series have been splitted in 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.
