What this PR does / why we need it:
This PR refactors the signal handlers, and their effects, to be thread-safe. Thread-safety is not something we need right now, but it is preparatory for #2074.
Also, this defines a termination condition for the Falco output engine. Basically, a full queue would generally imply a deadlock for Falco, so we exit with an error in that case.
