First cut at dealing with jdb
regexp.el: add field for class name, and stop event
command.el: add callback to get parse location info. Needed for java
trepan2,trepan3k: note that <string> is a pseudo-fiile
jdb: closer, but not functional yet.
track.el: "Unable to match.." message was wrong. Deal with no source-str better
/init.el: start adding clear command
send.el: start to add class name for upcoming jdb
