[lib] Fix the struct message LOOKUP function to be more robust
2008-02-28 Paul Jakma <paul.jakma@sun.com>
* log.c: (mes_lookup) Sowmini Varadhan diagnosed a problem where
this function can cause a NULL dereference, on lookups for unknown
indices, or messages with NULL strings. Can occur, e.g., debug
logging code when processing received messages. Fixed to accept a
pointer to a default string to be used if there is no match.
* log.h: LOOKUP adjusted to match

* linklist.c: This implementation expects that the data pointer not
be null, e.g. listgetdata() asserts this. The list add methods
don't apply the same sanity check.
