Choose a specific network interface

For example, if you want to force all torrent traffic through a VPN on a specific network interface.

Good point, and should allow changing the default port as well. E.g. -i for interface, -p for port. Maybe something like -r for random free port.

Done (except random listening port, I'll leave it for the future):

• Config#getAcceptorAddress() and Config#getAcceptorPort() are now respected throughout the library, and not just in the incoming connections acceptor
• CLI client received two new options: -i and -p (see README)

Specifically, the changes should affect:

• incoming connections acceptor
• outgoing peer connections
• http tracker requests
• udp tracker requests

I haven't been able to investigate how DHT performs socket binding yet. Need to address it later, so I'll leave this open for now.

It would be great if somebody has access to VPN (or multiple NICs) and can check this out.

Confirmed this is working. Turned on VPN -> start downloading with -i [VPN ip] -> download starts as expected -> kill VPN -> download dies, confirming that the VPN was being used. Started again with the VPN off -> exception.

Not sure if this is expected to work, but I tried with "-i eth1" and I get "Failed to parse the acceptor's internet address". It would be convenient if it could resolve iface name -> ip address.

Thanks for doing this!

Need to also take advantage of new config option in mldht
