[PATCH 1/8] xen/evtchn: make evtchn_bind_interdomain global

[Rahul Singh <rahul.singh@xxxxxxx>]

Event channel support will be added for dom0less domains to allocate
static event channel. It is necessary to have access to the
evtchn_bind_interdomain function to do that, so make
evtchn_bind_interdomain global and also make it __must_check.
