lib/httpserver: stop the process on panics in request handlers
...
Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic
instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers.
See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.
