A random(ish) colletion of libxl patches. - Fixup idl infrastructure naming clash/annoyance - Consolidate libxl_button_press and libxl_send_trigger - Change the way libxl exposes CPU topology information to be a list of CPU (core,node,socket) tuples instead of three lists. This is a more sensible representation but is also a bit easier on the language bindings. Plus: - Cause xl to use JSON with the "xl create -d" option and similar output. This follows the 20 patches in my "libxl: drop device_model_info" series.

libxl: Rename libxl IDL infrastructure.
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.

libxl: remove libxl_button_press in favour of libxl_send_trigger.
send_trigger already included all the operations covered by button_press.
Rework send_trigger to take an enum instead of a string.
I stopped short at removing the xl "button-press" command but instead
have
marked it as deprecated.

libxl: add named enum for timer mode.
Unlike previous iterations of this patch the enum values now match the
underlying domctl values.
I looked at updating xl.cfg(5) for these while I was here but frankly, even
after reading the comment in xen/include/public/hvm/params.h, I don''t
have a
clue what they mean, no_missed_ticks_pending in particular might as well be
written in klingon...
For the same reason I didn''t try and give the enum more user-friendly
names.

xl: use json output by default
Move the sxp producing code off into a separate file. It is supported
for legacy reasons and needn''t be updated other than the improve
compatibility with xm.
libxl_domain_config is not currently generated by the IDL (adding the
necessary support for Array types is on my to do list) so hand code
the json generation function for now.
Since this rather directly exposes a libxl data structure it''s not
clear what sort of forward compatibility guarantees we can
make. However it seems like it should be as stable as libxl''s own API
(which we are looking to stabilise)

This is quite ugly to have out here in the caller. Perhaps we should
provide a helper for this, called libxl_cputopology_free or
