needs cleanup and tests

Removed the socket.shutdown() before socket.close() again, this seemed to cause some errors with the statistics tests (which we will look into separately)

Discussed on jabber

callable() has been removed in Python 3, but was reintroduced in Python 3.2. This fix (check for isinstance(obj, collections.Callable) should make the test work with 3.1 and older versions of 3.

(acked on jabber)

- reduced a line that was 1 character too long
- flipped order of check with isdigit()
- renamed Token::NUMBER_RANGE to Token::NUMBER_OUT_OF_RANGE

- add std:: to strerror calls
- clean up and const_cast long_options array

If omitted the build fails on Solaris complaining that distance is unknown.

Which got accidentally removed in the previous commit
