new lightweight generics implemenation. (Newer MacOS X/iOS code assuming
the presence of the generics annotations can otherwise not be compiled with
GNUstep). This should be well-behaved under clang and gcc both.
Fix NSCache which was copying the cache keys when it really shouldn't
have. Added a few test cases for eviction behaviour.
Few smaller tweaks to avoid compiler warnings.

Note: The padding ivar has been added to NSRegularExpression. This will break the ABI for anyone subclassing NSRegularExpression, but hopefully that's no one (done before the next release, to make sure that we don't break the ABI between releases, only for people following -trunk).
