acb0ef5801 dump: Make DumpState and endian conversion routines available for arch-specific dump code 
Make DumpState and endian conversion routines available for arch-specific dump
code by moving into dump.h. DumpState will be needed by arch-specific dump
code to access target endian information from DumpState->ArchDumpInfo. Also
break the dependency of dump.h from stubs/dump.c by creating a separate
dump-arch.h.

This patch doesn't change any functionality.

56c4bfb3f0 dump: rebase from host-private RAMBlock offsets to guest-physical addresses 
RAMBlock.offset                   --> GuestPhysBlock.target_start
RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end
RAMBlock.length                   --> GuestPhysBlock.target_end -
                                      GuestPhysBlock.target_start

"GuestPhysBlock.host_addr" is only used when writing the dump contents.

This patch enables "crash" to work with the vmcore by rebasing the vmcore
from the left side of the following diagram to the right side:

2a78636bd2 dump: Drop qmp_dump_guest_memory() stub and build for all targets 
qmp_dump_guest_memory() calls dump_init() and returns an Error when
cpu_get_dump_info() returns an error, as done by the stub.
So there is no need to have a stub for qmp_dump_guest_memory().

Enable the documentation of the always-present dump-guest-memory command.

That way we can drop CONFIG_HAVE_CORE_DUMP and leave configure
completely out of the picture for target CPU features.
