Update all L0 Sysman getHandle routines to match spec.

Browse Source 
Updated all the getHandle routines to use the following
algorithm:
    n = min(*pCount, available)
    if (*pCount == 0 || *pCount > available) {
        *pCount = available;
    }
    if (pArrayn != nullptr) {
        for(i = 0; i < n; i++) {
            pArray[i] = handle[i];
        }
    }
