proposed patch

Okay this is it. It took me much much longer than expected, but I'm pretty
happy with the result now. These were my main objectives:

- match .NET's behaviour (both 2.0 and 1.1)
- follow all dependencies directly upon change
- keep lock on Cache's hashtable/dictionary to a minimum
- invoke callbacks without the lock held
- clean up the code (each of Cache/CacheItem/CacheDep should only contain code
handling its actual responsibilities)


The following open items I want to finish in the next few days:
- performance testing
- replace uses of HttpRuntime.InternalCache in System.Web with
HttpRuntime.Cache (and Cache.MakeInteral)
- make one little adjustment needed to match .NET 1.1 behaviour (HasChanged is
only toggled _after_ insertion into Cache).


Marek, could you have a look at the patch and tell me what you think? I hope we
can use it for the 1.1 profile as well. Do you now of any fundamental
differences between 1.1. and 2.0?
