Connector problems

[David Jencks]

Working with Tomasz Mazan we discovered that there was a permit leak  
in the connector pooling code (GERONIMO-3834).  While fixing this I  
revamped quite a bit of the pooling code and added several permit  
count and resizing tests, hopefully making it more reliable and  
reducing the bug count.

I think we should get this bug fix in g. 2.1 which will require  
releasing the "components" jars also.  I'm OK with a vote on the  
component jars + geronimo 2.1.

We might consider releasing 2.0.3 with this fix as well.
