score: Statically initialize user extensions
The initial extensions remain now in a read-only table and will not be
copied to work space memory. The extension chains are statically
initialized. This makes it possible to call _User_extensions_Iterate()
independent of the system state. It is now guaranteed that the fatal
callout of the initial extensions will be called provided the stack
pointer, the read-only data, and code memory are valid.
