Paolo Bonzini d8d9581460 memory: convert memory_region_destroy to object_unparent
Explicitly call object_unparent in the few places where we
will re-create the memory region.  If the memory region is
simply being destroyed as part of device teardown, let QOM
handle it.

Peter Maydell 6f1ce94a29 docs/memory.txt: Clarify and expand priority/overlap documentation
The documentation of how overlapping memory regions behave and how
the priority system works was rather brief, and confusion about
priorities seems to be quite common for developers trying to understand
how the memory region system works, so expand and clarify it.
This includes a worked example with overlaps, documentation of the
behaviour when an overlapped container has "holes", and mention
that it's valid for a region to have both MMIO callbacks and
subregions (and how this interacts with priorities when it does).

Marcel Apfelbaum 8002ccd6e4 docs/memory: Explictly state that MemoryRegion priority is signed
When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only
where no other region exists: rather than having to explicitly
specify a high priority for all the other regions, we can let them take
the default (zero) priority and specify a negative priority for the
background region.
