FFI: Simplified handling of custom ExternalAddress subclasses
Merged branches for FFI return type #pointer and #handle. Send
#initilize from C code and return from there rather than magically
change local variable and then hadling this in Smalltalk code
(this was bit tricky and hard to understand)

HandleRegistries are like Registries, in that they watch for the death of
a registered object. However, they send a self-change notification, passing the registered
handle as argument, instead of creating a shallow copy and letting it do the finalization.
Use Registry for objects which know themself how to clean up;
use HandleRegistry, if someone else does the cleanup.
