Automate abi compliance check
libzmq project has tried something to automate abi compliance checking process (recent travis builds are failing because of that though). Maybe we could do something similar as what they did: https://github.com/zeromq/libzmq/blob/02f7dca678095099be8774844fec693f390b2223/builds/abi-compliance-checker/ci_build.sh https://github.com/zeromq/libzmq/blob/9bb6b2142385b78d47811b73745b9c21ec366106/.travis.yml#L136-L143
