replace telnetlib with pwnlib as SimpleSocket base class

[sinitax]

related to #113 and #114

[domenukk]

readn is also in in Tubes as alias, so we could use this here, too

[sinitax]

true! I'll remove that

[domenukk]

Ah but we probably want to keep the automated timeout handling (or is this somehow handled in tubes, anyway?)

[sinitax]

It is, via the 'timeout' keyword arg!

I actually noticed that every recv function can be called via a corresponding read, same goes for send and write. Here is the code in question:

for _name in list(locals()):
    if 'recv' in _name:
        _name2 = _name.replace('recv', 'read')
    elif 'send' in _name:
        _name2 = _name.replace('send', 'write')
    else:
        continue
    locals()[_name2] = make_wrapper(locals()[_name], _name2)

The rest of our wrappers are still needed though because of our use of snake_case.

Ah, I was talking about self.current_default_timeout if we want to support this

[sinitax]

Then should I revert that last commit?

[domenukk]

I think it may be cleaner to handle timeout ourselves, also that way, we could add an additional exception_message to show in the scoreboard on timeout/eof

[sinitax]

how would we enforce the timeout? on the worker-level?

[domenukk]

Originally we calculated remaining time for each request, based on the total available time. I guess this is no longer strictly needed as the engine checks timeouts, too
