xen: allow global VIRQ handlers to be delegated to other domains
This patch sends global VIRQs to a domain designated as the VIRQ handler instead of sending all global VIRQ events to dom0. This is required in order to run xenstored in a stubdom, because VIRQ_DOM_EXC must be sent to xenstored for domain destruction to work properly. This patch was inspired by the xenstored stubdomain patch series sent to xen-devel by Alex Zeffertt in 2009.
