[sr-dev] json-c and rabbitmq-c

Hi List, there has been some problems trying to create builds for module kazoo due to the dependency of libraries (subject). i think that one possible (tested successfully) solution is to integrate these libraries in lib folder and distribute them as part of kamailio. i created them with "kamailio-" prefix and changed kazoo makefile to refer to these. if we proceed with this change, other modules dependent of json could also benefit from this inclusion. Thoughts ?
