Thanks.  And sorry for not reviewing this sooner.

I am happy with the API and ABI changes.

The situation with the expanding buffer functions (which I think is
the only thing you are moving?) is unfortunate.  We have some more of
similar code in libxl.  And probably elsewhere in the codebase.  It
would be nice to make them shared but I think that is a task for
another day.

The sanitise value functions should perhaps be exposed with more
enssible names ?

I think this was more difficult to review than it needed to be
particularly because of the mixture of code motion with other
changes.

Anyway, thanks for cleaning this up.  All evidence to the contrary, it
*is* appreciated.
