Message:

• sysinfo items "system.tasks" and "system.threads" now return complete statistics of all tasks and threads (statistics of individual tasks and threads can be still acquited from "system.tasks.#" and "system.threads.#")
• update user space functions accordingly
• cleanup top — it is fully functional again
