tar: rework the completion completely

Use the parsed 'tar --help' output for completion, at least for
GNU tar.  For non-GNU tars use the _posix_tar completion.  Adjust
the testsuite to cover some improvements.

# bash completion for GNU tar -*- shell-script -*- # bash completion for GNU tar -*- shell-script -*-
#
# General info
# ============
#
# The "old" style arguments
# -------------------------
#
# We don't "advice" the old tar option format by default for GNU tar, example:
#
# 'tar czfT /tmp/archive.tar patterns.txt'
#
# We rather advice the 'tar -czf /tmp/archive.tar -T patterns.txt' format of
# arguments. Though, if user starts the 'first' tar argument without leading
# dash, we treat the command line apropriately.
#
#
# long/short options origin
# -------------------------
#
# For GNU tar, everything is parsed from `tar --help` output so not so much
# per-distribution work should be needed. The _parse_help does not seem to be
# good enough so parsed here directly.
#
#
# FIXME: --starting-file (-K) (should be matched for extraction only)
# FIXME: handle already used (at least short) options
# FIXME: Test-cases for make check.
# - check for no global variable pollution
# FIXME: why PS4='$BASH_SOURCE:$LINENO: ' shows sometimes negative lines?
# FIXME: timeout on tarball listing
# FIXME: cache 'tar --help' parsing results into global variables
# FIXME: at least 'tar -<tab>' should show some helping text (apart from just
# pure option advices)
# FIXME: short option completion should be more intuitive
# - verbose mode option should be adviced multiple times
# - mode option should be adviced only once
# - format option should be adviced only once
