Subject: Replace ctrlc with signal-hook

Replaced the 'ctrlc' crate with 'signal-hook' for handling of SIGINT.
The 'signal_hook::low_level::register' function is actually unsafe.
However, according to
https://docs.rs/signal-hook/latest/signal_hook/low_level/fn.register.html,
it is only unsafe in the case of multithreaded applications. There are
some race conditions as well. For instance, it appears that even when we
fork to a child process, SIGINT is captured on both that process, as
well as the shell.
