Also, remove a stray line (apparently fallout from conflict resolution).

The reasoning is the same as for the corresponding qsvenc patch.

AVStream.codec is now deprecated. Allocate a separate codec context instead.

The switch is not yet complete because the parsers and the bistream filters do not have a new AVCodecParam-based API yet.

Open decoders first, next encoders. This makes sure that that subtitle_header is always set properly, without relying on avformat_find_stream_info() setting it.

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.

This API is intended to allow passing around codec parameters without using full AVCodecContext (which also contains codec options and encoder/decoder state).

Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.

Some files may be missing for valid reasons, e.g. on compile failure.

This way, the decisions about which protocols are available for use in any given situations can be delegated to the caller.

Disallow other code to touch it directly, now it's only accessible through a blacklisting/whitelisting function.

It needs to access the list of protocols directly, so it more properly belongs there.

It's a more appropriate place for it.

Instead of a linked list constructed at av_register_all(), store them in a constant array of pointers. Since no registration is necessary now, this removes some global state from lavf. This will also allow the urlprotocol layer caller to limit the available protocols in a simple and flexible way in the following commits.
