(COMMON_OBS): Add target-memory.o.
* memattr.c (lookup_mem_region): Adjust handling for
the top of memory. Improve comments.

from packet_ok. Recognize "E." as an error prefix.
(packet_ok): Use it.

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)

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.
(strtoulst): Moved to ...
* utils.c (HIGH_BYTE_POSN, is_digit_in_base, digit_to_int)
(strtoulst): ... here. Enhanced to behave more similarly
to strtoul.
* defs.h (strtoulst): New prototype.
* memattr.h: Include "vec.h".
(struct mem_region): Remove linked list pointer.
(mem_region_s): New typedef and corresponding vector.
* memattr.c: Include "vec.h".
(mem_region_chain): Delete.
