Currently we allow configuring the 'poll-max-ns',
'poll-grow', and
'poll-shrink' parameters of qemu iothreads only during runtime and they
are not persisted. Add XML machinery to persist them.

All these are int64_t in QEMU, although I understand we don't need to
represent all the possible values, but it is weird when each one is
different here.
I think you can't go wrong here if you make all of them unsigned long
long.
