Major overhaul of the SyncPPP layer. Basically, this comprises now a

full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.
