* This commit addresses multiple problems in the broker part of AMS
- we are not sending input/output as encoded string anymore, we send binary blobs
- base64 has been removed
- a bug has been fixed with (very) old libevent version (<= 2.0.21-stable)
- offloading inputs/outputs to the thread managing RMQ is now much faster

* Moved to ResourceManager, created AMSMessage structures, moved to smart pointers.

* Complete re-design of the RabbitMQ backend

* Removed EventBuffer, removed pthread and signals. Big cleanup of the code.

* Added documentation and new AMSMsgHeader class + moved from memcpy to ResourceManager::copy
