Preesm 3.8.1 and Thread Exit Control

We have released Preesm version 3.8.1. The main change consist in the renaming of the global variable that controls how the application exits. This variable used to be stopThreads and is now prefixed with preesm to give preesmStopThreads. This update requires the user applications to reflect this change. To have an idea of the impact, you can have a look at our updated application repository.
