src: Refactoring common.hpp and minimizing exposed includes
Face class has relatively large rewrite to hide internals using
Implementor pattern. As of this commit, <boost/asio.hpp> is not
automatically included whenever ndn-cxx/face.hpp is included. If it is
needed to directly work with io_service, asio.hpp should be specifically
included.
