I changed the url scheme so we always use pax maven urls for  
everything in the geronimo repository, and now I can get, with some  
work, all the plugin bundles to start as bundles.  However they mostly  
don't start as plugins (i.e., no gbeans start).  I haven't figured out  
why yet.

How to get it to "run":

unpack the assembly (geronimo-framework) and start it as before

The first start, it hangs for me, I think it's still trying to permute  
through some large space of possiblitiles.  However, killling the  
server and restarting doesn't have this problem.

You can then run osgi:list to see which plugins didn't get activated,  
and run osgi:start on them.

Looking at config.xml, they all get load="false" added.

I think the next step might be to start writing some gogo commands to  
operate on the ConfigurationManager.  This looks fairly straightforward.

Other stuff that needs to happen:

- figure out how to use pax logging and what we need to remove so we  
don't interfere.  I think when g. logging starts up it effectively  
shuts off all logging.
- Clean up dependencies so we aren't installing a lot of stuff we  
don't want, like un-osgi-ified versions of jaxb impl, stax-api, asm,  
etc etc etc.
- Clean up generation of geronimo-plugin.xml metadata so it isn't  
nested.  I added the nesting for one-classloader-per-jar and it needs  
to be removed again.
- Figure out how to get the DependencyManager to not try to install  
bundles that are already installed.  I guess we can get the location  
of each installed bundle from the bundle context and compare with the  
mvn url string we'd use for installing the new bundle.

- lots and lots of code cleanup.

If anyone wants to take a look at any of these, that would be great.   
I'm going to be mostly offline thursday through sunday but will try to  
answer any questions that may come up.
