Mark Johnston 7bb441c866 libdwarf: Add some constants from DWARF 5
This is not exhaustive - DWARF 5 has some new enumeration types not
implemented here - but I think I caught all the ones that are extended
in DWARF 5, plus the new compilation unit type (DW_UT_*), needed when
parsing .debug_info headers.

These were useful when extending libdwarf/ctfconvert/readelf to handle
DWARF generated by gcc 12, which is version 5 by default.

The Elftoolchain Project
========================

.. contents:: Table of Contents

Description
-----------

This software implements essential compilation tools and libraries for:

- managing program objects conforming to the ELF_ object format, and
- for managing DWARF_ debugging information in ELF objects.

The project currently implements the following utilities and
libraries:

=========== ============================================
Name        Description

ar          Archive manager.
addr2line   Debug tool.
brandelf    Manage the ELF brand on executables.
c++filt     Translate encoded symbols.
elfcopy     Copy and translate between object formats.
elfdump     Diagnostic tool.
findtextrel Find undesired text relocations.
libdwarf    DWARF access library.
libelf      ELF access library.
mcs         Manage comment sections.
nm          List symbols in an ELF object.
