internal: added ability to terminate input modules not via pthread_cancel...

... but an alternate approach via pthread_kill. This is somewhat safer as we
do not need to think about the cancel-safeness of all libraries we use.
However, not all inputs can easily supported, so this now is a feature
that can be requested by the input module (the most important ones
request it).
