New Features, Improvements & Bug fixes

• [ FESA-5346] - Fixed a mutex alignment problem that could under very specific circumstances create a spin-lock and make the FEC unresponsive. The problem was visible only if one had at least N+1 concurrency layers on a N-CPU system (typ. 2) and that those layers were at different priorities. In this situation, there was a likelihood that, while a low-priority concurrency layer was swapping the setting double buffer (critical section), two high-priority concurrency layers tried to enter the same critical section. This would lead to the high-priority threads to spin-lock on the mutex and freeze the system. The spin-lock phenomenon was due to the pthread_mutex_t structure to be misaligned during the shared memory mapping. As the critical section is very short, the likelihood was small but not null. The problem was visible for both mixed and split modes.
