vfio: selftests: add iova allocator
Add struct iova_allocator, which gives tests a convenient way to generate
legally-accessible IOVAs to map. This allocator traverses the sorted
available IOVA ranges linearly, requires power-of-two size allocations,
and does not support freeing iova allocations. The assumption is that
tests are not IOVA space-bounded, and will not need to recycle IOVAs.
This is based on Alex Williamson's patch series for adding an IOVA
allocator [1].
