[PATCH 0/6] Implement memory_region_new_* functions

[BALATON Zoltan <balaton@eik.bme.hu>]

Our documentation says that memory regions are automatically freed
when the owner dies and the reference counting to do this is also
implemented. However this relies on the QOM free funtion that can only
be set by creating objects with object_new but memory API only
provides constructors that call object_initialize which clears the
free function that prevents QOM to manage the memory region lifetime.
Implement corresponding memory_region_new_* functions that do the same
as the memory_region_init_* functions but create the memory region
with object_new so the lifetime can be automatically managed by QOM as
documented.

BALATON Zoltan (6):
  memory: Add internal memory_region_set_ops helper function
  memory: Factor out common ram region initialization
  memory: Factor out more common ram region initialization
  memory: Shorten memory_region_init_rom_nomigrate
  memory: Add internal memory_region_register_ram function
  memory: Add memory_region_new* functions
