Add support for stateful MPPE (microsoft encryption) providing

encryption compatibility with Windows 2000.  Stateful encryption
uses less CPU but is bad on lossy transports.

The ``set mppe'' command has been expanded.  If it's used with any
arguments, ppp will insist on encryption, closing LCP if the other
end refuses.

Unfortunately, Microsoft have abused the CCP reset request so that
receiving a reset request does not result in a reset ack when using
MPPE...
