Drop 0001-add-cstdlib-header-to-ensure-EXIT_FAILURE-presence.patch since
it's already upstream.
Rebase shared/static build patches - these look unnecessary if we switch
to cmake-package, however it seems to require the zmq package switches
to cmake-package as well since static library naming looks different,
which might be a problem for users.
Also set the minimum required version of gcc to 4.7.x since the code now
requires c++1x.
