38a4be3fa7 lavf: use number of output pictures for delay checks. 
This fixes false positives of has_codec_delay_been_guessed() for
streams where not every input picture generates an output picture,
such as interlaced H264.

61856d06eb probe: Restore identification of files with very large id3 tags and no extension. 
Restore behavior of identifying files with huge id3 tags as
mp3 at AVPROBE_SCORE_MAX/4. This was broken in r25378 and subsequently
removed in r25929.

7a773d4d59 probe: Remove id3 tag presence as a criteria to do file extension checking. 
This only encourages our users to put id3v2 tags on non-mp3 files to opt
into extension based probing.

a2faa95151 lavf: make some seeking functions private 
Specifically av_update_cur_dts(), av_seek_frame_binary() and
av_gen_search().

They are not supposed to be called outside lavf.

9ef6c7977f avformat: do not require frame_size for Speex. 
Having it there forces decoding of a frame in order to get frame_size, but it
is not really needed for proper demuxing or decoding.

569129a6dc lavf: add avformat_new_stream as a replacement for av_new_stream.

0041cdba98 avformat: don't unconditionally call ff_read_frame_flush() when trying to seek. 
This prevents flushing the packet buffer when the input format does not
support seeking.

a31e9f68a4 lavf: fix signed overflow in avformat_find_stream_info() 
On the first iteration through this code, last_dts is always
INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in
an invalid manner.  Although the result is only used if the
input values are valid, performing the subtraction is still
not allowed in a strict environment.

bb416bd68c lavf: do not set codec_tag for rawvideo 
If the demuxer did not set a codec_tag, there is none and
inventing one makes no sense.  This change stops the rawvideo
"decoder" over-writing user-supplied pixfmt with one derived
from the codec_tag.  The pixfmt-codec_tag-pixfmt round-trip
is lossy since several pixfmts map to the same codec_tag.

This fixes fate-lavf-pixfmt with avfilter disabled.
