Support to liveupdate C XenStored daemon was added during the 4.15
development cycle. Add a section in SUPPORT.MD to explain what is the
support state.

For now, it is a tech preview.

Oh, I read your answer as there is no support. I can resend a patch with 
the following title:

"LiveUpdate of C/Ocaml XenStored daemon"

Cheers,

I'd put it at tech preview, just like Cxenstored.  In particular, it has
the same issues concerning outstanding transactions.

It might however be worth having separate line items in SUPPORT.md to
start with, just in case the different implementations progress to
supported at different times.  (More likely, as there isn't an embargo
adding urgency the work now.)

I have some work planned for C XenStored to mitigate that as Paul 
recently discovered that some Windows PV drivers may leak transactions 
(see [1]).

Sure. Let me respin the patch.
