This checkin enables finding out the request method and response status

of a URL_LOAD event.  I'm still working on getting the request body via
the nsIUploadChannel interface.  Next step will be to get that working.
I'm currently running into problems where the END_URL event for a POST
doesn't have a status.  I think this is because I'm using the
Navigation.post() method rather than simulating a user post by pressing
a form submit button.

A classes_spec/org/mozilla/webclient/impl/wrapper_native/NativeInputStream.java
A src_moz/NativeInputStreamImpl.cpp

- Class to enable reading the post body from the request.

M build.xml

- add NativeInputStream to JNI generation
