Add a new symbol DOMID_ANY to improve the readability of the code.
Update all relevant domid_alloc() call sites and harden the domid_alloc()
input value check.
Also, fix problem with passing invalid domain IDs in
XEN_DOMCTL_createdomain: turns out libxl__domain_make() (toolstack)
uses 0xffff as domain ID.
Fix failing tools tests too.
