Message:

taskman: Handle INIT_TASKS as tasks spawned by loader

• everyone is connected to its spawner, except for INIT_TASKS, they are connected to taskman (first binary)
• taskman is now aware even of INIT_TASKS and taskman itself
• refactored taskman handshake — NS session is created lazily
• refactored async.c with usage of create_session
• changed EINVAL to EINTR on lost waits
• removed TODOs from taskman and related libc TODOs
