a758c5e2 added probing for various tools, such as AS. Unfortunately, GNU
AS is reading stdin with -v, and thus configure is stalled with
configure arguments such as --as=as.

This is incompatible with libavcodec version
55.18.100 to 55.43.100 except 55.39.101
This incompatibility is caused by these libavcodec versions depending on
a libavutil 52 which is ABI incompatible with the previous ABI 52

you can avoid this incompatibility by upgrading your libavcodec so it
does no longer depend on the invalid ABI

ffmpeg: Do not fill gap before the first decodable frame on single stream input files unless the user explicitly requests it.

Fixes different behavior to JM and probably several if not all
reference decoders.

We cannot just do this unconditionally as it would ruin AV sync in
some use cases.

The not handling of frame gaps has lead to the lack of a dummy reference
frame, which has lead to the failure of decode_slice_header() which has
lead to one SEI recovery message being skiped which had introduced a
slightly suboptimal recovery point for at least 1 h264 file compared to
JM.

This patch adds CODEC_CAP_DELAY support to avcodec_decode_subtitle2.

For DVB teletext decoding, a single teletext packet can contain multiple
teletext pages. In order to support that, the teletext decoder may buffer
some pages.
