Implement trigger s3resume
This is the equivalent of xm trigger s3resume and it is implemented the
same way: using an ACPI state change.

The code here is a bit odd - callers are apparently expected to pass
strings rather than enums through into the libxl API. I think
trigger_type_from_string ought to be libxlu_...
But given the current code and the state of freeze we shouldn't do
that now.
This is clearly a low-impact new feature and I'm inclined to make
exception to the freeze for it. Have you tested the patch ? Anyone
object ?
Thanks,
Ian.
