Extend autoreconf `-v' option

[Noah Misch]

With this patch, `autoreconf -vv' yields the usual autoreconf verbose output and
also passes --verbose to tools it calls that support it.

Not all versions of Perl we support shipped a Getopt::Long that supported
incremental options, but that feature was easy to mimic.

        * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
        subordinate tools.
        * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
        * doc/autoconf.texi (autoreconf Invocation): Document it.
