More cleanups. Stop using __ identifiers for internal stuff now that it's properly marked private and we don't have to worry about conflicts.

Return "nil" instead of nil from class_getName with a nil argument. This is stupid (what happens if you have a class called nil?) but it is what OS X does.

Fixed crash when resolving user-allocated classes (e.g. KVO) revealed by r31482.
...
objc_resolve_class() does ((Class)objc_getClass((char*)cls->isa->isa))->isa;
but cls->isa->isa was a metaclass object and not a C string if the class was
user-created. objc_allocateClassPair() has been changed to set the
meta-metaclass as a C string and not an object, so that objc_getClass() does
not return Nil.

Fix introspection with type-dependent dispatch enabled. Looking up a method with an untyped selector was failing because the UID for the selector was no longer the same for all type variants.
...
As a side-effect of this change, method lookups for introspection are now much faster. They use the slot lookup mechanism to find which class has the method declared and then only need to do the linear search on that class, rather than doing the linear search on the entire hierarchy (slow!). If the method is not present, then they can give up after two memory accesses, rather than after searching a few hundred list entries, but that's a less important case.
I also noticed while tracking down this bug that the implementation of methodSignatureForSelector in GNUstep is very inefficient. I'll tweak that next.

Fixed some issues in runtime.c when looking up methods. This fixes some issues with DO.

Removed GNU dtable and sparse array implementations, replaced entirely now with versions based on the Étoilé runtime. Performance is roughly equivalent in microbenchmarks, memory usage is significantly lower (Gorm goes from 95MB to 50MB on my machine - this will be even more pronounced on 64-bit systems), which should improve cache usage considerably. Still room for some performance tuning, however.

Tidied up some bits by creating private headers for private data structures.
...
Imported selector table code frm the Étoilé runtime. We can now make dispatch type dependent with a -D switch. Not enabled yet, but it will be enabled in a warning mode soon - I consider preferable to the existing GNU and Apple solution of corrupting the stack.
