[PATCH xenbus 04/12] Use Windows types in XEN_API event channel functions

[Paul Durrant <paul@xxxxxxx>]

From: Paul Durrant <pdurrant@xxxxxxxxxx>

Other XEN_API functions use Windows types rather than Xen types in most cases.
There is no good reason why functions related to event channels need expose
types such as 'domid_t' or 'evtchn_port_t' to callers, especially when the
callers already use USHORT and ULONG types (respectively) for those quantities.

No functional change.
