FreeRTOS handles were stored plainly and they were deleted in the destructor of classes. This meant that if a class were to be copied, the destructor would be called twice on the same handles and lead to double-free. Seha on Discord suggested to fix this by using `std::unique_ptr` with a custom deletion function. The changes affect: - Thread - Semaphore - Mutex - StreamBuffer - Timer - MessageQueue - EventFlag Thread changes: - Removal of the hack with the `Data` struct - Thread's main body is now just a private static function inside the class. - The C functions were relocated to static class members PubSub changes: - Refactored pubsub into class - Renamed files to `PubSub` instead of `Pubsub` - `PubSubSubscription` is now a private inner struct and `PubSub` only exposes `SubscriptionHandle` Lockable, ScopedLockable, Mutex: - Added `lock()` method that locks indefinitely - Remove deprecated `acquire()` and `release()` methods - Removed `TtWaitForever` in favour of `portMAX_DELAY`
