xen, xen-tools: add recipes for Xen 4.14

Add a versioned-suffix pair of recipes for Xen 4.14, allowing selection
of which Xen version to build via setting PREFERRED_VERSION.

4.14 is currently still pre-release, so the new recipes for it set
DEFAULT_PREFERENCE to -1, and the default for now remains the existing
stable version. Forward ports of patches needed for 4.14 are included.

Implementation note: since both this version and the git recipe are
built from git branches -- important for Xen since significant updates
are made available there inbetween point releases -- the recipe includes
'stable' as a string in PV so as to distinguish it from 'git' in the git
recipe, and thereby allow PREFERRED_VERSION to select the correct recipe
in the situation where both happen to be configured with the same XEN_REL.
