Previously device ids in libxl were treated as integers meaning they
were being initialized to 0, which is a valid device id. This patch
makes devid its own type in libxl and initializes it to -1, an invalid
value.
This fixes a bug where if you try to do a xl DEV-attach multiple
time it will continuously try to reattach device 0 instead of
generating a new device id.

And leave to the caller the burden of knowing and remembering what kind
of bitmap each instance of libxl_bitmap is.
This is basically just some s/libxl_cpumap/libxl_bitmap/ (and some other
related interface name substitution, e.g., libxl_for_each_cpu) in a bunch
of files, with no real functional change involved.
A specific allocation helper is introduced, besides libxl_bitmap_alloc().
It is called libxl_cpu_bitmap_alloc() and is meant at substituting the old
libxl_cpumap_alloc(). It is just something easier to use in cases where one
wants to allocate a libxl_bitmap that is going to serve as a cpu map.
This is because we want to be able to deal with both cpu and NUMA node
maps, but we don't want to duplicate all the various helpers and wrappers.
While at it, add the usual initialization function, common to all libxl
data structures.

And make all the required infrastructure updates to enable this.
Since there are currently no uses of this type there is no change to
the generated code.

Currently when running the bootloader libxl will update b_info->u.pv.kernel,
.ramdisk, .cmdline and .bootloader. This can expose internal details, such
as temporary paths in /var/run/xen/bootloader.*/ to the user. This is
problematic because it means that the user cannot re-use the struct as is.
This does not effect xl in Xen 4.2+ since it always reparses the guest config
and reinitialises the build info, however it did cause issues with reboot in
4.1 (reported by Dmitry Morozhnikov) and may cause issues for other users of
libxl.
Instead make the libxl bootloader infrastructure provide output to its caller
which is slurped into the internal libxl__domain_build_state datastructure. If
no bootloader is configured then the bootloader instead propagates the user
supplied b_info config.
In order to simplify this push the error handling for the case where there is
no bootdisk down into libxl__bootloader_run. In principal there is no reason
why it shouldn't be possible to do a pure netboot guest with a suitable
bootloader, but I don't fix that here.
This change allow us to make the libxl_file_reference an internal API, and
eventually we might be able to get rid of it.
Also removes the publix libxl_run_bootloader interface, neither xl nor libvirt
use it.
I am proposing this for 4.2 due to the API change.

Consitently make such fields 64 bit values as used by dominfo.
It is not clear if ->video_memkb and/or shadow_memkb shouldn't be part of

Originally libxltypes.py provided the infrastructure and libxl.idl provided the
specific types.
In 23887:a543e10211f7 libxl.idl became libxl_types.idl (to allow for
libxl_types_internal.idl) which means we now have libxl_types.FOO and
libxltypes.FOO providing different things and annoying people in tab
completion.
Rename the infrastructure as idl.

This provides for fields in libxl datatypes which are only present in
the C version of structures and are used only by libxl itself. This
is useful when a libxl datatype wants to contain fields which are used
by libxl internally and which are only present in the structure to
avoid additional memory allocation inconvenience.

Destroy is an overloaded term which would commonly like to be used for actual
destructive operations, such as destroying a domain etc.
Dispose isn't a great term but it does the job.

Two functions are provided. TYPE_gen_json exposes an interface which is
compatible with the YAGL generator infrastructure. TYPE_to_string uses this to
produce a pretty printed string.
The TYPE_gen_json functions are defined in a new header libxl_json.h which is
not exposed via libxl.h due to the use of YAGL datatypes to avoid poluting the
namespace us libxl users which don't use the library themselves. If a libxl
user is interested in integrating at the YAGL level then it should #include
this file itself.
Also update testidl to generate a random version of each IDL datastructure and
convert it to JSON. Unfortunately this requires a libxl_ctx and therefore the
test must be run on a Xen system now.
