vaapidecode: don't reset decoder if codec type is the same. Reset, i.e. destroy then create, the decoder in _setcaps() handler only if the underlying codec type actually changed. This makes it possible to be more tolerant with certain MPEG-2 streams that get parsed to form caps that are compatible with the previous state but minor changes to "codec-data".

decoder: use GstVideoCodecState. Use standard GstVideoCodecState throughout GstVaapiDecoder and expose it with a new gst_vaapi_decoder_get_codec_state() function. This makes it possible to drop picture size (width, height) information, framerate (fps_n, fps_d) information, pixel aspect ratio (par_n, par_d) information, and interlace mode (is_interlaced field). This is a new API with backwards compatibility maintained. In particular, gst_vaapi_decoder_get_caps() is still available.
