It allows to configure how long will avformat_find_stream_info() wait
to get the first timestamp.

The only flags, for now, indicate if metadata was updated and are set after each call to
av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly
as packets might be buffered in AVFormatContext.packet_buffer before being given to the user
in av_read_frame().

It should provide a quicker guess for elementary streams provided
by http.

The AVStream.parser field is considered private and its location cannot be
preserved while preserving also ABI compatibility to libav, as libav added fields
before it.
Some tools like ffmpeg.c access this field though

The callers should now set the stream timebase, not the codec one.

Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

Provide f_strict for avconv usage.

Currently probesize is cliped at 1mb before being used for format detection.
Alternatively this cliping could be removed but this would then tie various
things like stream analysis to the file detection.

Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

After this commit applications needs to call av_format_inject_global_side_data()
or handle AVStream side data by some other means if they want it not to be lost.
