We need to protect access to the param_values array. This is dynamically allocated and resized (utarray_reserve() calls realloc). If some thread was iterating the array while another was resizing the array, the first one would iterate on a freed array, thus accessing invalid memory. On NuttX this could lead to hardfaults in rare conditions. Unfortunately we need to initialize the semaphore on startup, by calling sem_init(). This adds a param_init() method called by every board/config that uses the params (at least I think I've found all of them)
