We can express the offset of old portio completely via
MemoryRegionPortio::offset by splitting up regions of different offsets
and adjusting those offsets appropriately.

Please split into two patches - core and isa.

+    /* Copy the sub-list and null-terminate it.  */
+    pio = g_new(MemoryRegionPortio, count + 1);
+    memcpy(pio, pio_init, sizeof(MemoryRegionPortio) * count);
+    memset(pio + count, 0, sizeof(MemoryRegionPortio));

Wish: g_copy(pio, pio_init, count);  // aka std::copy()

So long as mr->offset exists, you need to take it into account.  And I 
don't want to remove memory_region_set_offset() until everything (that 
can potentially use it, at least) has been converted.
