[RTC] ?? Review requested on intermediate patches for pluggable JACC

[David Jencks]

I've attached some patches for an incremental step towards pluggable  
JACC to http://issues.apache.org/jira/browse/GERONIMO-1563

Pre RTC I would check these in and pray that someone would notice and  
if I was really lucky comment, and then continue with the next  
steps.  We'll see how RTC works with this.  In particular I intend to  
continue work on this stuff on my flight today so I don't actually  
expect to check in these patches.  I do think that there's enough  
there to see where I'm headed and object if you don't like it.

These patches turn the security builder into a gbean implementing a  
SecurityBuilder interface, and move stuff around with module  
dependencies so it still works.  The next steps are:

- make multiple security namespaces possible and to determine if a  
namespace driven scheme is plausible: it might be even though I don't  
think we can run more than one JACC implementation in a geronimo  
instance at once.

- review the SecurityBuilder interface, especially the parts used by  
TSSEditor

- provide an additional JACC implementation to prove this stuff  
works.  See if there's any spec-specific functionality in our current  
security builder that can be moved into a superclass or helper for  
use by other builders.
