Brian Somers 542962ddf9 Introduce another global (MPPE_IsServer) so that we initiate the
MPPE session keys correctly.

I'm a bit dubious about this code.  It seems that the session keys
are initialised differently based on whether you're the client or
the server.  One side is the server if it issues the first challenge,
but of course you can issue a challenge from both sides.... at the
same time.  Sounds like another wonderful M$ assumption...

Ppp can now talk to itself correctly using encryption.
