…#944) Audio decoders now automatically discard priming samples if present in the bitstream or configuration description. Decoded outputs have their initial timestamps adjusted forward by the duration of discarded priming samples. - Add [[priming samples to discard]] slot to AudioDecoder. - In configure(), initialize slot from description if specified. - In decode(), update slot from chunk data if specified. - In Output AudioData, discard priming samples up to slot value, decrement slot, discard completely dropped outputs, and adjust surviving output's timestamp forward by discarded duration rounded to microseconds. Fixes #944 See #626 TAG=agy CONV=fb1a957f-7551-4aa1-b394-2244fb156d73

Audio decoders now automatically discard priming samples if present in the bitstream or configuration description. Decoded outputs have their initial timestamps adjusted forward by the duration of discarded priming samples.
Due to a bikeshed stacking issue, the codec registry is updated in a secondary PR.
