Exposing fileio is misleading

• Operating System: Linux

Using fileio to check if anything is available to read is misleading, because it only reflect the state of the socket, not the internal buffer. Because of this, messages in the internal buffer may go unnoticed.

As with the latest release, I've decided to remove the fileio function for the time being.
But I'm planning on making something similar in the next release, as this would be an useful function.
