exec: simplify destruction of the phys map

Do not bother visiting the radix tree when an address space is destroyed.
After the previous patch, this has become a pointless exercise. When
called from address_space_destroy_dispatch, all you're doing is zeroing...

memory: add getter for owner

Whenever memory regions are accessed outside the BQL, they need to be
preserved against hot-unplug. MemoryRegions actually do not have their
own reference count; they piggyback on a QOM object, their "owner".
The owner is set at creation time, and there is a function to retrieve...

memory: introduce memory_region_present

This new API will avoid having too many memory_region_ref/unref
in paths that currently use memory_region_find.

memory: add ref/unref calls

Add ref/unref calls at the following places:

- places where memory regions are stashed by a listener and
used outside the BQL (including in Xen or KVM).

- memory_region_find callsites

- creation of aliases and containers (only the aliased/contained...

exec: check MRU in qemu_ram_addr_from_host

This function is not used outside the iothread mutex, so it
can use ram_list.mru_block.

exec: move qemu_ram_addr_from_host_nofail to cputlb.c

After the next patch it would not be used elsewhere anyway. Also,
the _nofail and the standard versions of this function return different
things, which is confusing. Removing the function from the public headers...

ioport: Move portio types to ioport.h

This decouples memory.h from ioport.h, concentrating all portio related
types in a single header.

memory: destroy phys_sections one by one

phys_sections_clear is invoked after the dispatch tree has been
destroyed. This leaves a window where phys_sections_nb > 0 but the
subpages are not valid anymore, which is a recipe for use-after-free
bugs.

Move the destruction of subpages in phys_sections_clear. We will...
