Urgent bugs caused by ndn-cxx change 3603
In the ndn-cxx change 3603 "Remove previously deprecated headers, methods, and constants", we removed a bunch of deprecated headers/methods/constants from ndn-cxx. This change caused urgent bugs in ChronoChat.
To fix the urgent bug, one needs to compile and install the latest commit of ndn-cxx change 3603 and compile ChronoChat and fix all the urgent bugs.
In the ndn-cxx-breaks run (https://travis-ci.org/yoursunny/ndn-cxx-breaks/builds/235341547), some bugs are caused by the missing header identity-certificate.hpp.
