numfmt: support zero padding using --format="%010f"
* src/numfmt.c (setup_padding_buffer): Simplify the code by not
explicitly dealing with heap exhaustion.
(parse_format_string): Likewise. Handle multiple grouping
modifiers as does the standard printf. Handle the new leading
zero --format modifier.
(double_to_human): Use more defensive coding against overwriting
stack buffers. Honor the leading zeros width.
(usage): Mention the leading zero --format modifier.
(main): Allow --padding in combo with a --format (width),
as the number of leading zeros are useful independent of
the main field width.
* doc/coreutils.texi (numfmt invocation): Likewise.
* tests/misc/numfmt.pl: Add new test cases.
* NEWS: Mention the improvement.
