libxl/xl: implement support for guest ioport and irq permissions.
This is useful for passing legacy ISA devices (e.g. com ports,
parallel ports) to guests.
Supported syntax is as described in
http://cmrg.fifthhorseman.net/wiki/xen#grantingaccesstoserialhardwaretoadomU
I tested this using Xen's 'q' key handler which prints out the I/O
port and IRQ ranges allowed for each domain. e.g.:
(XEN) Rangesets belonging to domain 31:
(XEN) I/O Ports { 2e8-2ef, 2f8-2ff }
(XEN) Interrupts { 3, 5-6 }
