Re: [Xen-devel] [PATCH v7 3/6] public/xen.h: add a definition for a 'valid domid' mask

A subsequent patch will modify libxl to allow selection of a random domid
value when creating domains. Valid values are limited to a width of 15 bits,
so add an appropriate mask definition to the public header.

NOTE: It is reasonable for this mask definition to be in a Xen public header
       rather than in, say, a libxenctrl header since it relates to the
       validity of a value passed to XEN_DOMCTL_createdomain. This new
       definition is placed in xen.h rather than domctl.h only to co-locate
       it with other domid-related defitions.
