Improve objcopy's note mergeing capabilities.
* objcopy.c (struct merged_note_section): New structure. Used to
chain together details of mergeable note sections.
(is_merged_note_section): Rename to is_megreable_note_section and
return true for note sections that use GNU_BUILD_ATTRS_SECTION_NAME
as a prefix.
(num_bytes): Delete
(objcoopy_internal_note): Add padded_namesz field.
(DEBUG_MERGE): New macro. Set to non-zero to enable debugging of
the note merging code.
(gap_exists): Rename to overlaps_or_adjoins and return TRUE for
overlapping notes or adjoining notes.
(contained_by, is_deleted_note, is_version_note)
(compare_gnu_build_notes, sort_gnu_build_notes): New functions.
(merge_gnu_build_notes): Rework. Sort notes into a mergeable
order first. Merge them. Then sort them into an ascending
address order before writing them out.
(copy_object): Handle more than one mergeable note section.

behaviour.
