     * dwarfdump.c: dump_unique_errors_table() ifdef out
       of normal compiles, it is unused. Unused local variables
       removed.
       Update version string.
     * esb.c: Moved stdarg.h include just after stdio.h include
       for positioning consistency.
     * globals.h: Added stdarg.h include just after stdio.h
       include as we use va_list a lot and so stdarg.h
       is required.
     * print_debugfission.c: Remove two unused local variables.
     * print_frames.c: Remove trailing whitespace.
     * tag_attr.c: #include stdarg.h. Add {} to array initializers
       output to avoid compiler warning.
     * tag_common.c: Move stdarg.h include to just after
       stdio.h for positioning consistency.
       Update version string.
     * tag_tree.c: Revised include order to start with
       globals.h and to not duplicate includes of stdio.h etc.
       Add {} to array initializers
       output to avoid compiler warning.
     * testesb.c: Add include of stdarg.h.

     * tag_common.c: Add comments about va_start, va_end.
     * esb.c: Add comments about va_start, va_end.
       Add va_end in the selftest code.
     * common.c: Update version string.
     * dwarfdump.c: Update version string. Add va_end()
       and comments about va_end.
2015-01-08  David Anderson and Carlos Alberto Enciso
     * Makefile.in: add selftest: rule, which tests esb.c
     * dwarfdump.c: Add new options -O file=path, -kD -kG -ku kuf.
       New checking and reporting features intended to give a
       report on attribute and tag usage.
       Update version string.
     * common.c: Update version string.
     * esb.c, esb.h: Added new interface using stdarg.
       Added self-test feature.
     * dwarf_makename.c: new #pragma (not Linux/Unix related).
     * print_die.c: Implements collecting the new statistics
       dwarfdump reports.
     * print_lines.c: New statistics collected.
     * tag_attr.c: New checks for the tag/attr table correctness.
     * tag_attr.list: Fixes duplicated entries.
     * tag_attr.list_ext: Adds APPLE attribute DW_AT_APPLE_optimized
       that llvm emits.
     * tag_common.c: bad_line_input() now allows stdarg calls so
       its easier to emit good error messages.
     * tag_common.h: bad_line_input() arg list changed a little. Stdarg now.
     * tag_tree.c: New tag tree checking done. New statistics
       available.
     * tag_tree.list:  Adds DW_TAG_unspecified_type,
       DW_TAG_rvalue_reference_type,
       DW_TAG_restrict_type.
     * tag_tree_ext.list: Adds DW_TAG_GNU_template_template_parameter.
       Fixes duplication of entries.

     * dwarfdump.c:  Don't call dwarf_finish() if
       the dwarf-init call failed.
     * common.c,dwarfdump.c: Updated version string.

     *	A new year begins.
