lib: Revise handling CDAP messages

Fixes a number of issues in CDAP.

CDAP keeps track if a message is being processed, and moves it to the
end of the request list if it is. It will now correctly wait for new
messages.

The invoke_ids are generated locally per CDAP instance, invoke_ids
can't be used to track incoming requests, we need to keep track of the
fd. The keys are now identifiers (taken from the same local pool as the
invoke_ids) that are used to track requests.
