applications/traces: renamed agent -> couch_agent
applications/traces: split the server code between trace-specific and web-specific; introduced amqp_agent.
traces: implemented trace_couch
traces: default to AMQP request / CouchDB response.
traces: not trying to keep old retrieval methods
traces: added couchdb_daemon proxy
bin/ccnq3: allow to use underscore instead of space in command names
bin/ccnq3: install as setuid ccnq3, accessible to users in group `ccnq3`
split ccnq3-manager package, so that the CouchDB and RabbitMQ configurations can be replicated on another server (e.g. to help bootstrap a `shared` host).
bin/ccnq3 is now setuid and will-do-the-right-thing when ran as root.
corrected variable location
Need to expand variables.
Setting ccnq3 setuid was not enough; enforcing differently.
bin/ccnq3: make sure crypto is available everywhere
