Nick Clifton 6f156d7a4a Add support for v3 binary annotation notes.
I am checking in the attached patch which updates the binutils
  support for version 3 binary annotation notes.  (Version 3 adds
  an end address to the ranges covered by the notes, so that it
  is possible to detect gaps in the coverage).

  This patch also stops the note merging feature of objcopy from
  executing if the notes have relocations against them.  This makes the
  code simpler, and prevents the problems with architectures which have
  unusual relocation management issues.

	* objcopy.c (objcopy_internal_note): New structure.
	(gap_exists): New function.
	(is_open_note): New function.
	(is_func_note): New function.
	(is_64bit): New function.
	(merge_gnu_build_notes): Handle v3 notes.  Do not merge
	if there are relocations against the notes.
	* readelf.c (get_note_type): Use short names for build attribute
	notes.
	(print_symbol_for_build_attribute): Rename to
	get_symbol_for_build_attribute.  Returns the found symbol rather
	than printing it.
	(print_gnu_build_attribute_description): Maintain address ranges
	for function notes as well as global notes.  Handle v3 notes.
	(print_gnu_build_attribute_name): Use more space for printing the
	name in wide mode.
	* testsuite/binutils-all/note-2-32.s: Use .dc.l instead of .word.
	Eliminate symbol references in order to remove the need for
	relocations.
	* testsuite/binutils-all/note-2-64.s: Likewise.
	* testsuite/binutils-all/note-3-32.s: Add a size to the note_1
	symbol.
	* testsuite/binutils-all/note-3-64.s: Likewise.
	* testsuite/binutils-all/mips/mips-note-2r-n32.d: Update expected
	output.
	* testsuite/binutils-all/mips/mips-note-2r-n64.d: Likewise.
	* testsuite/binutils-all/mips/mips-note-2r.d: Likewise.
	* testsuite/binutils-all/note-2-32.d: Likewise.
	* testsuite/binutils-all/note-2-64.d: Likewise.
	* testsuite/binutils-all/note-3-32.d: Likewise.
	* testsuite/binutils-all/note-3-64.d: Likewise.
	* testsuite/binutils-all/note-4-64.s: New test.  Checks v3 notes.
	* testsuite/binutils-all/note-4-32.s: New test.
	* testsuite/binutils-all/note-4-64.d: New test result file.
	* testsuite/binutils-all/note-4-32.d: New test result file.
