demux: do not make up demuxer_id
The demuxer_id (exported in as "src-id" property) is supposed to be the native stream ID, as it exists in the file, or -1 if that does not exist (actually any negative value), or if it is unknown. Until now, an ID was made up if it was missing. That seems like strange non-sense, and I can't find the reason why it was done. But it was probably for convenience by the EDL stuff or so. Stop doing this. Fortunately, the src-id property was documented as being unavailable if the ID is not known. Even the code for this was present, it was just inactive until now. Extend input.rst with some explanations. Also fixing 3 other places where negative demuxer_id was ignored or avoided.
