Anton Staaf	a6da62d284	Queue: Add functionality needed by new USART stream driver ... Previously there was no way to remove multiple units at a time from the queue, and the queue was wasting an entry to disambiguate full from empty. There was also no way to get the free entry count from the queue, only the ability to query if it was above a required amount. The queue was also storing its constant compile time configuration as well as its dynamic state in the same structure. This wasted RAM on configuration information that doesn't change. This refactor fixes these issues, making the queue suitable for use in the new USART stream driver.
