sysinfo overhaul

• cleanup (nicer data structures, use of SLAB allocator)
• add support for storing arbitrary binary data
• properly reimplement non-constant values (generated by functions)
• add support for non-constant subtrees (generated by functions)
• syscall ABI change, libc API change
• reflect changes in user code

libc: task_spawn() can now return error code
