2020-09-23 fayang Discard initial key right after a HANDSHAKE packet has been sent and unify the fixes for missing initial keys. This goal is to make sure an endpoint never tries to serialize initial frames (could be pending frames or re-serialize initial packet in the coalescer) while initial key gets dropped.
