C++ migration: use std::jthread, std::condition_variable, std::chrono.

win32 pthread support is gone
new setting configure.shutdown_mode for cancellation of free-running threads at shutdown.
no more hard thread termination! If a thread doesn't cooperate, an error is raised.
lane.status "killed" is gone
lane:cancel can't force-kill.
