What protocols init functions are meant to is to be called once to set the default configuration before user specific configuration is set. Until now, we reset to the default configuration just before reconnecting, thus without allowing any time frame to let users change it. That was fine until one user asked to be able to do that. This change move protocols init functions calls from ppp_clear to ppp_new, meaning user configuration is not overwritten anymore.
