To address the issue of listening for XMLHttpRequest traffic, I've taken

a cue from Doron Rosenberg in #developers and looked at the Eclipse ATF
project's XHRObserver.java.

This was my first look at java code that uses the java xpcom bridge, and
I'm very impressed.  Once I get webclient 2.0 done, I'll definately
rewrite as much as possible of the mozilla implementation using the java
xpcom bridge.  For now, I'm going to continue to crank with my
"on-demand hand coded JNI C++" approach.  I think I can get results
pretty quickly with this.  For example, just yesterday I learned that
the regular nsIWebProgressListener doesn't get notifications on Ajax
requests, and now I see a way to do it (thanks to Doron).

Here is the work in progress.

A webclient/src_moz/AjaxListener.cpp
A webclient/src_moz/AjaxListener.h
M logging.properties

- set "ALL" for MCP level

M dist/mcp-test/src/test/java/cardemo/CarDemoTest.java

- Cause an Ajax transaction to happen

M webclient/classes_spec/org/mozilla/mcp/MCP.java

- log messages for outgoing HTTP requests

M webclient/src_moz/EmbedProgress.cpp
M webclient/src_moz/EmbedProgress.h

- Leverage new AjaxListener class

M webclient/src_moz/Makefile.in

- add xmlextras, to include nsIXMLHttpRequest.
