Improve raised exceptions

convert message from bytes to string when using Python 3 (using str.decode should work on both Python 2.x and Python 3)
add result code and errno values to the NNError exception class when raising an exception

The last change allows to react appropriately when we are interested in specific errno, i.e. EAGAIN to repeat send operation.

Removed result_code. I assume it will be always -1 on error.

The *args, **kwargs are part of Exception.__init__ signature, so just retaining the interface.
