libzmq3 crashes when 'getifaddrs()' is unavailable

[Adam Seering]

libzmq3 crashes when used on a computer where the kernel is unable to provide any information about network-device addresses.

This is uncommon with normal Ubuntu configurations. But is currently always the case with Ubuntu as run under the new Windows Subsystem for Linux.

This has already been diagnosed and fixed upstream:
https://github.com/jupyter/notebook/issues/1331

I have backported the fix; an updated package (based on the stock Ubuntu 14.04 package but with the backport as an added patch) is available in this PPA:
https://launchpad.net/~aseering/+archive/ubuntu/wsl

This has been reported in a couple other bugtrackers. Even with the fix in a PPA, there's still some amount of user confusion:
https://github.com/jupyter/notebook/issues/1331
https://github.com/Microsoft/BashOnWindows/issues/185

It would be great if this fix could be pulled into Ubuntu 14.04 directly, so that people stop hitting this bug.

Status changed to 'Confirmed' because the bug affects multiple users.
