b08b2d0f34 More tweaks for garbage collection mode, including making NSNotificationCenter use weak pointers (things are never removed if it uses strong pointers because they remove themselves in the -dealloc method, which is never called, and can't remove themselves in the -finalize method because the -finalize method would not be called until after they have been removed - this is consistent with Apple behaviour). 
Gorm now works correctly when built with GC enabled.

6068e9484c Initial pass at implementing fully Apple-compatible GC. This requires the code to be built with -fobjc-gc or -fobjc-gc-only, and requires a runtime that implements all of the support functions (GNUstep runtime trunk or 1.5 when it's release). 
Currently, there are a few places where we should be calling NSAllocateCollectable() without NSScannedOption, but are actually calling NSZoneMalloc() unless we're in GC mode.  We should not need separate code paths for this anywhere outside NSZone, since NSAllocateCollectable() will work in non-GC mode as well.

A few of the changes should be tweaked slightly so that they do run-time tests.  For example, when compiling with -fobjc-gc, we may be linked against non-GC code, which will use -retain and -release but won't use the memory barriers.  Supporting this nicely is a lot of effort, and I'm not fully convinced it's a good idea.

0239c9b9a5 Use NSClassFromString() to look up NSZombie class. This has two advantages: 
1) Doesn't rely on Apple-incompatible behaviour in the GCC runtime that introduces fun heisenbugs.
2) Doesn't require constructing the dtable for NSZombie if we're not actually using it.

0d28d838fd Revert last commit. The actual Apple behaviour is what libobjc2 used to do, not what it does now. It's incredibly ugly, and should not have been allowed: It makes NSObject the superclass of NSObject's metaclass, but does NOT do the same transform for any other classes.

a8cd2e588c Make [NSObject -class] return self if self is a class. This is needed for a weird bit of the ObjC spec relating to metaclasses of root classes. The GNUstep runtime behaviour mimics the Apple behaviour, while the GCC runtime mimics the StepStone behaviour, so we get some somewhat irritating differences.
