This adds a reusable class for a simple FIFO ringbuffer. Signed-off-by: Julian Oes <julian@oes.ch>
This adds a reusable class for a FIFO ringbuffer that accepts variable length packets. It is using the Ringbuffer class internally. Signed-off-by: Julian Oes <julian@oes.ch>
This switches from the horribly intertwined ringbuffer implementation to the new VariableLengthRingbuffer implementation. By ditching the previous implementation, we fix MAVLink message forwarding, which didn't work reliably. The reason it didn't work is that multiple mavlink messages could be added but only one of them was sent out because the buffer didn't keep track of the messages properly and only read the first one.
