Eric Auger 9ab5741164 util/vfio-helpers: Rework the IOVA allocator to avoid IOVA reserved regions 
Introduce the qemu_vfio_find_fixed/temp_iova helpers which
respectively allocate IOVAs from the bottom/top parts of the
usable IOVA range, without picking within host IOVA reserved
windows. The allocation remains basic: if the size is too big
for the remaining of the current usable IOVA range, we jump
to the next one, leaving a hole in the address map.
