error, mux: coded remux errors; MKV writer hardening; damage rules for key checks

Browse Source 
E9077-E9084 for engine remux and preflight refusals; MuxOptions loses
its send deadline. The MKV writer drops unwrap/expect and overflow
paths, tags SDR BT.2020 correctly, leaves out streams with no Matroska
CodecID and derives the Dolby Vision level. On-arrival damage with no
vouching partner is blanked, and a garbled head is damage, not a stop.
