libxl: add support for image files for NetBSD
Created a helper function to detect if the OS is capable of using
image files as phy backends. Create two OS specific files, and
changed the Makefile to choose the correct one at compile time.

libxl: introduce libxl__wait_for_device_state
This is a generic function, that waits for xs watches to reach a
certain state and then executes the passed helper function. Removed
wait_for_dev_destroy and used this new function instead. This
function will also be used by future patches that need to wait for
the initialization of devices before executing hotplug scripts.

libxl: remove force parameter from libxl_domain_destroy
Since a destroy is considered a forced shutdown, there's no point in
passing a force parameter. All the occurences of this function have
been replaced with the proper syntax.
