Add pretty-printing of .debug_gnu_pubnames, .debug_gnu_pubtypes.
* dwarf.c (get_gdb_index_symbol_kind_name): New function. (display_debug_pubnames_worker): Renamed from display_debug_pubnames. Add support for .debug_gnu_pubnames, .debug_gnu_pubtypes. (display_debug_pubnames, display_debug_pubnames_gnu): New functions. (display_gdb_index): Redo printing of symbol kind. (debug_displays): Add .debug_gnu_pubnames, .debug_gnu_pubtypes. * dwarf.h (dwarf_section_display_enum): Add gnu_pubnames, gnu_pubtypes. * readelf.c (process_section_headers): Add gnu_pubnames, gnu_pubtypes.
