Fix suspending with process groups - #49
Merged

Conversation
Since using raw mode via `raw.lflag &= ~(… | termios.ISIG)` pyrepl needs
to handle SIGSTOP itself, but before this patch would only signal its
own process.
Using `0` for the pid signals the process group instead.
Manual test:
When running the following from a shell `Ctrl-z` will not give you the
shell's prompt, but the process is stuck, and needs to be signaled to
continue using `kill -CONT $pid`:
> python -c 'import os; os.system("python pyrepl/reader.py")'
I have noticed this when using pdbpp with pytest, which was wrapped in a
shell script, not using `exec python …`.

I have not seen this to be necessary, but it goes in line with handling SIGSTOP then (pypy#49).
