Add support for the MADV_FREE advice argument when discarding pages.
Specifically we add an option to perform a lazy discard for use with free
page reporting as this allows us to avoid expensive page zeroing in the
case that the system is not under memory pressure.

Add support for the page reporting feature provided by virtio-balloon.
Reporting differs from the regular balloon functionality in that is is
much less durable than a standard memory balloon. Instead of creating a
list of pages that cannot be accessed the pages are only

Add support for what I am referring to as "free page reporting".
Basically the idea is to function very similar to how the balloon works
in that we basically end up madvising the page as not being used. However
we don't really need to bother with any deflate type logic

We need to make certain to advertise support for page poison tracking if
we want to actually get data on if the guest will be poisoning pages. So
if free page hinting is active we should add page poisoning support and
let the guest disable it if it isn't using it.

Ok, I get you now.
But still, having fixed number of MSIs is less flexible. E.g:
- for x86, processor can only deal with about 250 interrupt vectors.
- driver may choose to share MSI vectors [1] (which is not merged but we will
for sure need it)
