Make a consistency in pppoe options

Remove 'rp_' prefix from all pppoe options and ensure that pppoe options
have 'pppoe-' prefix. Also change underlines to dashes to be consistent
with other pppd options.

To not break a backward compatibility ensure that old option names still
work via (legacy) aliases.

Also document everything in pppd manual page.
