memory: add address_space_access_valid

The old-style IOMMU lets you check whether an access is valid in a
given DMAContext. There is no equivalent for AddressSpace in the
memory API, implement it with a lookup of the dispatch tree.

memory: add address_space_translate

Using phys_page_find to translate an AddressSpace to a MemoryRegionSection
is unwieldy. It requires to pass the page index rather than the address,
and later memory_region_section_addr has to be called. Replace
memory_region_section_addr with a function that does all of it: call...

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

The radix tree is statically sized to fit TARGET_PHYS_ADDR_SPACE_BITS.
If a larger memory region is registered, it will overflow.

Fix by limiting any section in the radix tree to the supported size....

memory: make memory_global_sync_dirty_bitmap take an AddressSpace

Since this is a MemoryListener operation, it only makes sense

memory: Rename readable flag to romd_mode

"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region...

memory: allow memory_region_find() to run on non-root memory regions

memory_region_find() is similar to registering a MemoryListener and
checking for the MemoryRegionSections that come from a particular
region. There is no reason for this to be limited to a root memory...

memory: introduce memory_region_test_and_clear_dirty

This function avoids having to do two calls, one to test the dirty bit, and
other to reset it.
