This patch allocates interrupt lines among VMs according to the PCI devices
assigned to them.
v1 -> v2:
* Remove the usage of VMx_PT_INTX_NUM macro in vm_configuration.c; use the
concrete numbers directly.
* The static allocator will also complain if any interrupt line is allocated to
a VM with LAPIC_PASSTHROUGH.
v2 -> v3:
* Fix a minor coding style issue.
