Avi Kivity 3095115744 memory: iommu support 
Add a new memory region type that translates addresses it is given,
then forwards them to a target address space.  This is similar to
an alias, except that the mapping is more flexible than a linear
translation and trucation, and also less efficient since the
translation happens at runtime.

The implementation uses an AddressSpace mapping the target region to
avoid hierarchical dispatch all the way to the resolved region; only
iommu regions are looked up dynamically.

[Modified to put translation in address_space_translate; assume
 IOMMUs are not reachable from TCG. - Paolo]
