Warner Losh 99c02d39bc Fix many buffer overruns in the code. Specifically, disallow ExpandString
to be used to expand things beyond the size of the buffer passed in.  Also
do a general cleanup of sprintf -> snprintf as well as strcpy and strncat
safety.  Also expand some buffers to allow for the largest possible data
that might be used.

This is a 2.2 candidate.  However, it needs to be vetted on -current
since little testing has been done on this due to my lack of PPP on
this machine.

(otherwise ppp's behavior remains unchanged) and documented by myself,
Steve Sims, Nate Williams, Martin Renters and god-only-knows who else. :-)
