Changes in help messages

[Pavel Roskin]

Hello!

"man autoconf" still recommends using --macrodir but autoconf itself says
it's obsolete.

On the other hand, "man autoreconf" recommends using --autoconf-dir but
autoreconf rejects this option.

ChangeLog:
        * autoconf.sh: Usage info made consistent with other tools.
        Recommend using --autoconf-dir instead of --macrodir.
        * autoreconf.sh: Actually accept --autoconf-dir. Make
        --macrodir obsolete. Remove --macro-path from the usage info.

Regards,
Pavel Roskin
