Support remote IRB

[st0012]

(originally proposed by @zzak)

Description

Currently IRB can't be used without direct access to standard IO. This makes it hard to use with tools like foreman.

If we expect IRB to become a more powerful debugging tool, especially after #575 and similar enhancements, the need to connect to it remotely will only grow.

Implementation

1. Centralise IRB's IO interaction (Avoid using arbitrary puts to print output #580)
2. Enhance the IO layer with remote connecting medium options (TCP/IP, Socket...etc.)
3. TBD
