Time for 2.2?

[Justin Erenkrantz]

Looking at nd's recent mod_rewrite and mod_include changes including the aaa 
rewrite (and some other changes and new modules that just weren't backported), 
I'm starting to think this is about the 'right feel' for a 2.2 release.  2.1 
has essentially been open since last September.

So, I think we should start producing 2.1 unstable releases with a goal of 
producing a stable 2.2 release in a few months.

The one issue I'd like resolved before starting a 2.1 release cycle is 
figuring out if we can axe ap_*_client_block (as this is a major API change). 
I think Sander's mentioned something about changing how authorization hooks 
are called, but I don't know if he's prepared to do it 'soon.'

Thoughts?  -- justin
