In addition to the ignore-invalid-option (commit 8ea49cf5) it is often
useful to mark options in a configuration which as NOP. For example
options which have no more function at all but can be expected to be
found in existing conf files. Such an option (or command) may now be
given as
ARGPARSE_ignore (300, "obsolete-option")
The 300 is merely used as a non-valid single option name much like
group names or the 500+n values used for long options.

(initialize): Init field IIO_LIST.
(ignore_invalid_option_p): New.
(ignore_invalid_option_add): New.
(ignore_invalid_option_clear): New.
(optfile_parse): Implement meta option.

This option is currently of no use. However, as soon as it has been
deployed in all stable versions of GnuPG, it will allow the use of the
same configuration file with an old and a new version of GnuPG. For
example: If a new version implements the option "foobar", and a user
uses it in gpg.conf, an old version of gpg would bail out with the
error "invalid option". To avoid that the following line can be put
above that option in gpg.conf
ignore-invalid-option foobar
This meta option may be given several times or several option names
may be given as arguments (space delimited). Note that this option is
not available on the command line.
