This allows selecting if the demuxer should consider all streams to be
found after the first PMT and add further streams during decoding or if it rather
should scan all that are within the analyze-duration and other limits

The emulation is unused and causes compilation trouble on systems
where fminf() is defined in <math.h> but missing from libm.
This should fix compilation on Debian powerpcspe.

This avoids a potential crash if writing a fragmented psp mp4
(which probably is only a hypothetical scenario).

new_output_stream creates a codec context with arbitraty picked codec.
Later data is updated, but priv_data are left alone.
There is a bit chance there is a mismatch between codecs.

In matroska_read_seek(), |tracks| is assigned at the begining of the function.
However, functions like matroska_parse_cues() could reallocate the tracks so
that |tracks| can get invalidated.
This CL assigns |tracks| only before we use it so that it won't be invalidated.

Previously we wrote decoding timestamps here, while the specs

When using the new first_trun flag instead of checking the track id,
we don't need to have a special case for the separate_moof flag
any longer.
This simplifies the complicated codepath ever so slightly.

In this case, shift tracks to start from zero instead (potentially
stretching the first sample in tracks that start later than the
first one).
Some software does not support edit lists at all, the adobe flash
player seems to be one of these. This results in AV sync errors when
edit lists are used to adjust AV sync.
Some players, such as QuickTime, don't respect the duration for
audio packets, so if an audio track starts later than the video
track and the first audio sample gets a duration longer than the
actual amount of data in it, the result will be out of sync.
Based on patches by Michael Niedermayer.

This is the same logic as is invoked on AVFMT_TS_NEGATIVE,
but which can be enabled manually, or can be enabled
in muxers which only need it in certain conditions.
Also allow using the same mechanism to force streams to start
at 0.
