* Makefile.in (SFILES): Add target-memory.c.

	(COMMON_OBS): Add target-memory.o.
	* memattr.c (lookup_mem_region): Adjust handling for
	the top of memory.  Improve comments.
	* remote.c (packet_check_result): New function, split out
	from packet_ok.  Recognize "E." as an error prefix.
	(packet_ok): Use it.
	(remote_write_bytes_aux): New function, renamed from
	remote_write_bytes.  Take packet header, packet format,
	and length flag as arguments.
	(remote_write_bytes): Rewrite to use remote_write_bytes_aux.
	(remote_send_printf, restore_remote_timeout)
	(remote_flash_timeout, remote_flash_erase, remote_flash_write)
	(remote_flash_done): New.
	(remote_xfer_partial): Handle flash writes.
	(init_remote_ops, init_remote_async_ops): Set to_flash_erase
	and to_flash_done.
	* symfile.c (struct load_section_data): Include a pointer to
	the cumulative stats and a request queue.  Move most members
	to other types.
	(struct load_progress_data, struct load_progress_section_data): New
	types.
	(load_progress): Handle a NULL baton and zero bytes.  Update for
	type changes.
	(load_section_callback): Create memory write requests instead of
	writing to memory.  Don't print the progress message here.
	(clear_memory_write_data): New function.
	(generic_load): Use target_write_memory_blocks.
	* target-memory.c: New file.
	* target.c (update_current_target): Mention new uninherited methods.
	(memory_xfer_partial): Issue an error for flash writes.
	(target_flash_erase, target_flash_done): New functions.
	(target_write_with_progress): Call the progress callback at the
	start also.
	* target.h (enum target_object): Add TARGET_OBJECT_FLASH.
	(target_write_with_progress): Update comment.
	(struct target_ops): Add to_flash_erase and to_flash_done.
	(target_flash_erase, target_flash_done, struct memory_write_request)
	(memory_write_request_s, enum flash_preserve_mode)
	(target_write_memory_blocks): New, including a vector type
	for memory_write_request_s.
