Andrew Cooper 50a21ee067 tools: Fix fallout from DOMID_ANY ABI breakage
Commit 23e2479ff9 ("xen/domain: introduce DOMID_ANY") broke at least:

 * xenstored domains
 * The Python bindings
 * The Ocaml bindings (i.e XAPI, and therefore XenServer/XCP-ng)

by causing Xen to reject 0 (the wildcard sentinel since the start of Xen) and
DOMID_INVALID (since 4.21) without adjusting the callers of xc_domain_create().

Under other circumstances I'd revert, but xenstored has gained a dependent use
of DOMID_ANY.

Fix up the remaining in-tree callers of xc_domain_create(), which covers
init-xenstore-domain and the python bindings.

The Ocaml C bindings, like libxc itself, expose this ABI detail to their
caller, but in this case the caller is still internal to the bindings as a
whole.  Adjust the default value in the internal transformation, adding
domid_any for legibility.

Leave a very clear message in CHANGELOG.md that all external callers need
altering.
