Add ``ipcp'' as an optional argument to ``open'', and make

open capable of re-negotiatiating the various layers.

It is now possible to change various link options and then
re-open the relevant layer, making the changes effective -
for example, switching off VJ compression or starting ECHO
LQRs on-the-fly.
