Threading

[Glen Daniels <gd...@macromedia.com>]

I just added a new SOAPSAXHandler child called SAXAdapter, which simply
parses the entire message when parse() is called, with no threads.  To try
it out, just replace the "ThreadedSAXAdapter" in Message.java with
"SAXAdapter".

I didn't do any serious testing, but it looks like the timings improved from
~55msg/sec with the ThreadedSAXAdapter to ~70msg/sec with the non-threaded
version.  More tomorrow...

It parses them into a SOAPEnvelope, with (by default) an RPC-style body.

We don't really want to be doing this, for a couple of reasons:

* It causes the entire message to be read into memory.

* We may not be able to determine the desired message format (RPC/Messaging,
plus available type mappings) until we've run through the header handlers
and parse the body to do a lookup/dispatch

The plan, I think, is to move to pull-style incremental parsing, but that's
a next step after we integrate Xerces-2, or XPP....
