Various bug fixes in libdw and eu-readelf dealing with bad DWARF5 data.

Thanks to running the afl fuzzer on eu-readelf and various testcases.

eu-readelf -N is ~15% faster.

Version 0.171

DWARF5 and split dwarf, including GNU DebugFission, are supported now.

Data can be read from the new DWARF sections .debug_addr, .debug_line_str,

.debug_loclists, .debug_str_offsets and .debug_rnglists.  Plus the new

DWARF5 and GNU DebugFission encodings of the existing .debug sections.

Also in split DWARF .dwo (DWARF object) files.  This support is mostly

handled by existing functions (dwarf_getlocation*, dwarf_getsrclines,

dwarf_ranges, dwarf_form*, etc.) now returning the data from the new

sections and data formats.  But some new functions have been added

to more easily get information about skeleton and split compile units

(dwarf_get_units and dwarf_cu_info), handle new attribute data

(dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies

that might come from different sections or files (dwarf_die_addr_die).

Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary)

files, the .debug_names index, the .debug_cu_index and .debug_tu_index

sections. Only a single .debug_info (and .debug_types) section are

currently handled.

readelf: Handle all new DWARF5 sections.

         --debug-dump=info+ will show split unit DIEs when found.
