Modify libxl to allow raw format file to use phy backend.
For the hotplug script part, learn from NetBSD's block hotplug script --
test the path and determine the actual type of file (block device or
regular file) then use the actual type to determine which branch to run.
With these changes, plus the current ordering of backend preference
(phy > qdisk > tap), we will use phy backend for raw format file by
default.

Since most of the needed work is already done in previous patches,
this patch only contains the necessary code to call hotplug scripts
for nic devices, that should be called when the device is added or
removed from a guest.
Added another parameter to libxl__get_hotplug_script_info, that is
used to know the number of times hotplug scripts have been called for
that device. This is currently used by IOEMU nics on Linux.

We will chain the launch of the disk hotplug scripts after the
device_backend_callback callback, or directly from
libxl__initiate_device_{add,remove} if the device is already in the
desired state.

Move a lot of
#include <stdfoo.h>
from individual files into libxl_internal.h. This helps avoid
portability mistakes where necessary system headers are omitted from
individual files, and is also of course a convenience when developing.
Also add
#include "libxl_osdeps.h" /* must come before any other headers */
to the top of most libxl*.c files, so that anyone who adds any headers
before libxl_internal.h will put the in the right place.

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.
