memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes...

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...

memory: Add iommu map/unmap notifiers

This patch adds a NotifierList to MemoryRegions which represent IOMMUs
allowing other parts of the code to register interest in mappings or
unmappings from the IOMMU. All IOMMU implementations will need to call
memory_region_notify_iommu() to inform those waiting on the notifier list,...

spapr: convert TCE API to use an opaque type

The TCE table is currently returned as a DMAContext, and non-type-safe
APIs are called later passing back the DMAContext. Since we want to move
away from DMAContext, use an opaque type instead, and add an accessor...

spapr: use memory core for iommu support

Now we can stop using a "translating" DMAContext, but we do not yet modify
the sPAPRTCETable users to get an AddressSpace; they keep using the table
via a DMAContext.

dma: eliminate old-style IOMMU support

The translate function in the DMAContext is now always NULL.
Remove every reference to it.

exec: Resolve subpages in one step except for IOTLB fills

Except for the case of setting the IOTLB entry in TCG mode, we can avoid
the subpage dispatching handlers and do the resolution directly on
address_space_lookup_region. An IOTLB entry describes a full page, not...

exec: return MemoryRegion from address_space_translate

Only address_space_translate_for_iotlb needs to return the section.
Every caller of address_space_translate now uses only section->mr,
return it directly.

Revert "memory: limit sections in the radix tree to the actual address space size"
