Yes, I agree. To add to the mess, io_mem_{read,write} are just
old-fashioned names for (static) memory_region_dispatch_{read,write}.
I need to understand whether/how the per-arch calls to
softmmu_template.h could be moved to exec.c. Then io_mem_{read,write}
can just disappear, and memory_region_dispatch_{read,write} can move to
memory-internal.h.
