This is backport from master

commit 3bc004decd

commit 0e8f6e2aa9

but without changing all functions names to gpgrt.  Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error.  This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions.  Tested builds
against 1.27 and 1.40-beta.

Note that g13-syshelp does not anymore default to --verbose because
that can now be enabled in /etc/gnupg/g13-syshelp.conf.
