patch for the update
libzmq4 in version 4.3.1 is outdated, 4.3.2 and 4.3.3 include fixes for several vulnerabilities.
Tried my best to provide a patch. Old patches to the source tree does not seem to be necessary, but apparently I need to fix some includes to get it to compile.
I would be glad to here some feedback on my patch. For instance where do the patch numbers come from? I just filled 1111 for now.
