encode: rename option --ometadata to --ocopy-metadata --copy-metadata describes the result of the option better, (copying metadata from the source file to the output file). Marks the old --no-ometadata OPT_REMOVED with a suggestion for the new --no-ocopy-metadata.

encode: implement --oset-metadata, and --oremove-metadata This commit introduces a new --oset-metadata key-value-list option, allowing the user to specify output metadata when encoding (eg. --oset-metadata=title="Hello",comment="World"). A second option --oremove-metadata is added to exclude existing metadata from the output file (assuming --ocopy-metadata is enabled). Not all output formats support all tags, but luckily libavcodec simply discards unsupported keys.

encode: rewrite half of it The main change is that we wait with opening the muxer ("writing headers") until we have data from all streams. This fixes race conditions at init due to broken assumptions in the old code. This also changes a lot of other stuff. I found and fixed a few API violations (often things for which better mechanisms were invented, and the old ones are not valid anymore). I try to get away from the public mutex and shared fields in encode_lavc_context. For now it's still needed for some timestamp-related fields, but most are gone. It also removes some bad code duplication between audio and video paths.

encode: get rid of the output packet queue Until recently, ao_lavc and vo_lavc started encoding whenever the core happened to send them data. Since audio and video are not initialized at the same time, and the muxer was not necessarily opened when the first encoder started to produce data, the resulting packets were put into a queue. As soon as the muxer was opened, the queue was flushed. Change this to make the core wait with sending data until all encoders are initialized. This has the advantage that we don't need to queue up the packets.

encode: don't access ao->pts This field will be moved out of the ao struct. The encoding code was basically using an invalid way of accessing this field. Since the AO will be moved into its own thread too and will do its own buffering, the AO and the playback core might not even agree which sample a PTS timestamp belongs to. Add some extrapolation code to handle this case.
