Subject: 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.
