2020-08-28: David Anderson
    * dwarf_die_deliv.c,dwarf_loc.c,dwarf_util.c:Fixed
      indents and trailing whitespace.
2020-08-27: David Anderson
    * dwarf_die_deliv.c: Some error messages now have more
      detail.
    * dwarf_line_table_reader_common.h: In an error condition
      (meaning corrupt dwarf) _dwarf_free_chain_entries()
      was called twice on the same data, referring to
      freed space in doing so. Deleted the extra call.
    * dwarf_loc.c(_dwarf_setup_loc): Removed a
      bogus _dwarf_error
      using DW_DLE_LOC_EXPR_BAD: Let the just-called
      function error code be returned.
      Some error conditions detected here now report
      detailed information on the error.
    * dwarf_query.c(dwarf_attrlist): Refined the detailed
      error message already present.
    * dwarf_util.c:New internal function
      _dwarf_create_area_len_error() lets dwarf_util.h
      macro report a more detailed error without
      bloating the macro.
    * dwarf_util.h: Calls that new function rather
      than calling _dwarf_error() itself.
2020-08-25: David Anderson
    * dwarf_form.c: Previous change failed to show
      the actual error string
      DW_DLE_STRP_OFFSET_BAD or DW_DLE_STRING_OFFSET_BAD
      along with the
      details. Oops. Now it shows.
2020-08-23: David Anderson
    * dwarf_form.c: Slightly changed the error message
      for an error in DW_FORM_strp.
2020-08-23: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarf_names_enum.h,
      dwarf_names_new.h,libdwarf_version.h: Updated  version
      string, regenerated files that reference it.
2020-08-23: David Anderson
    * dwarf_form.c,dwarf_generic_init.c,dwarf_loc.c,
      dwarf_loc.h,dwarf_loclists.c,dwarf_query.c, dwarf_rnglists.c,
      pro_opaque.h: Remove trailing whitespace. Fix indents.
2020-08-23: David Anderson
    * dwarf_form.c: In case an strp offset seems wrong
      we get a more detailed error message.
    * dwarf_macro5.c: Deleted gratuitous blank line.
2020-08-22: David Anderson
    * dwarf_loc.c,dwarf_rnglists.c: call
      _dwarf_look_in_local_and_tied_by_index
      not _dwarf_extract_address_from_debug_addr so
      .debug_addr in the tied file will be found.
    * dwarf_opaque.h,dwarf_query.c: Make
      _dwarf_look_in_local_and_tied_by_index global,not
      _dwarf_extract_address_from_debug_addr.
2020-08-22: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarf_names_enum.h,
      dwarf_names_new.h,libdwarf_version.h: Updated  version
      string, regenerated files that reference it.
2020-08-21: David Anderson
    * dwarf_init_finish.c(insert_sht_list_in_group_map):
      Added checks of dss_data_was_malloc around
      a couple of calls saying free(secdata.dss_data).
      The missing checks could only result in duplicate
      free with user calls that allocated their
      own section data to load a section and a certain
      error arising during the call.
    * dwarf_loc.c: To elminate ambiguity, renamed
      some fields from lowpc to rawlowpc (for example).
    * dwarf_loclists.c(build_array_of_lle): Removed
      a block of code duplicating work done in dwarf_loc.c.
      Fixed arguments passing ld_lopc, ld_highpc
      to pass ld_rawlow, ld_rawhigh for correctness.
2020-08-21: David Anderson
    * libdwarf2.1.mm: Rev 3.07. Corrected quote mismatches
      in the mm commands, and a couple of stray
      characters after a .P command
    * libdwarf2.1.pdf: Rev 3.07. Regenerated.
2020-08-18: David Anderson
    * checkexamples.c: Corrected example_rnglist_for_attribute()
      example.
    * dwarf_ranges.c: Corrected a comment and removed #if 0
      code as it is obsolete.
    * dwarf_rnglists.c(dwarf_get_rnglists_entry_fields_a):
      Allow the pointer-arguments used to return data to
      the caller to be null pointers safely, as libdwarf2.1.pdf
      suggested that was legal.
    * libdwarf2.1.mm: Version 3.06. Corrected the example
      calling dwarf_get_rnglists_entry_fields_a().
    * libdwarf2.1.pdf: Regenerated, Version 3.06


2020-08-10: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarf_names_enum.h,
      dwarf_names_new.h,libdwarf_version.h: Updated  version
      string, regenerated files that reference it.
2020-08-10: David Anderson
    * dwarf_elf_defines.h,dwarf_elfread.c: A linux kernel used a
      R_X86_64_NONE (which means ignore the relocation) and
      now we deal with it properly for EM_X86_64.
2020-08-02: David Anderson
    * dwarf_alloc.c: Added a constructor for Dwarf_Locdesc_c
      (DW_DLA_LOCDESC_C) so fields ld_lle_value and
      ld_kind get non-zero and
      erroneous initial values so
      the values can be checked later for correctness.
    * dwarf_errmsg_list.h: Added error DW_DLE_LOCATION_ERROR.
    * dwarf_loc.c: Now we rigorously set and check the fields
      ld_lle_value and ld_kind.
      _dwarf_locdesc_c_constructor() sets those two fields
      so we can check correctness and in case of error,
      report the details.
    * dwarf_loc.h: Added constructor prototype and a special
      DW_LLE_VALUE_BOGUS initial value (invisible to
      library callers).
    * dwarf_loclists.c: After malloc use the  Dwarf_Locdesc_c
      constructor so later error checking possible.
    * libdwarf.h.in: Added error DW_DLE_LOCATION_ERROR.
    * libdwarf2.1.mm: Rev 3.05. Additional detail on
      return values for dwarf_get_locdesc_entry_d()
      and documented dwarf_get_locdesc_entry_c()
      (recommending use of dwarf_get_locdesc_entry_d()
      instead)
