Currently we use a global radix tree to dispatch memory access. This only
works with a single address space; to support multiple address spaces we
make the radix tree a member of AddressSpace (via an intermediate structure
AddressSpaceDispatch to avoid exposing too many internals).
A side effect is that address_space_io also gains a dispatch table. When
we remove all the pre-memory-API I/O registrations, we can use that for
dispatching I/O and get rid of the original I/O dispatch.

exec-obsolete.h used to hold pre-memory-API functions that were used from
device code prior to the transition to the memory API. Now that the
transition is complete, the name no longer describes the file. The
functions still need to be merged better into the memory core, but there's
no danger of anyone using them.
