ftp: Limit user, password, arg and reply_msg column sizes in log

Browse source 
The user and password fields are replicated to each of the ftp.log
entries. Using a very large username (100s of KBs) allows to bloat
the log without actually sending much traffic. Further, limit the
arg and reply_msg columns to large, but not unbounded values.
