It was mentioned in #779 that SO_BINDTODEVICE is Linux only. I suppose I could surround with #ifdef statements; unless someone thinks there's a better way. If i have time i can experiment with other broadcast options. |

I was unable to get the response broadcast packets to be picked up by the receiving socket without SO_BINDTODEVICE. it's possible there is a linux kernel setting which will allow them to get through, but i was unable to figure it out. Reverse Path Filtering is turned off by default on the systems i'm testing with, so I'm kind of out of ideas and I suppose have to use the approach from this PR and run with root in order to use SO_BINDTODEVICE. |

When possible (running as root) uses SO_BINDTODEVICE to discover cameras outside the subnet.
I did not implement for Stream because the idea is that with this change you can now use arv-tool-0.8 (with root privelages) to re-address the camera and bring it back into communication for proper use.
I'm not sure if there's a better way that does not require root for SO_BINDTODEVICE.
