Nick Clifton 5c49f2cd78 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.
