Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.

On windows, rename(2) will fail if the target file exists. On unix this trick is used to make sure that people reading the file either will get the full previous file, or the full new version of the file, but no intermediate version. Signed-off-by: Martin Storsjö <martin@martin.st>

The chained flv muxer wants one set of tags - normally this set could be signaled via the AVOutputFormat codec_tag field (as smoothstreamingenc and dashenc do). hdsenc doesn't signal it, since the FLV codec tag arrays aren't exported from flvenc.c. This can lead to the caller keeping an original codec tag from the originating container here, which would then be a mismatch for the FLV muxer. Since we don't really care about what codec tag the caller might have set, just clear it and let the lavf muxer layer set the right one for the chained FLV muxer later instead.

Previously, the returned error codes were intentionally ignored (see fadd3a68), to avoid aborting if the directory already existed. If the mkdir actually failed, this was caught when opening files within the directory fails anyway. By handling the error code here (but explicitly ignoring EEXIST), the error messages and return codes in these cases are more appropriate and less confusing.
