dump: introduce GuestPhysBlockList
The vmcore must use physical addresses that are visible to the guest, notaddresses that point into linear RAMBlocks. As first step, introduce thelist type into which we'll collect the physical mappings in effect at the...
dump: populate guest_phys_blocks
While the machine is paused, in guest_phys_blocks_append() we register aone-shot MemoryListener, solely for the initial collection of the validguest-physical memory ranges that happens at listener registration time.
For each range that is reported to guest_phys_blocks_region_add(), we...
dump: rebase from host-private RAMBlock offsets to guest-physical addresses
RAMBlock.offset --> GuestPhysBlock.target_startRAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_endRAMBlock.length --> GuestPhysBlock.target_end -...
memory_mapping: Improve qemu_get_guest_memory_mapping() error reporting
Pass any Error out into dump_init() and have it actually stop on errors.Whether it is unsupported on a certain CPU can be checked by looking fora NULL CPUClass::get_memory_mapping field....

memory_mapping: Move MemoryMappingList typedef to qemu/typedefs.h
This will avoid issues with hwaddr and ram_addr_t when includingsysemu/memory_mapping.h for CONFIG_USER_ONLY, e.g., from qom/cpu.h.
