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.
