Current muxers only use a single bitstream filter, so there is no need to
maintain code which operates on a list of bitstream filters. When multiple
bitstream filters are needed muxers can simply use a list bitstream filter.
If there is a use case in the future when different bitstream filters should be
added at subsequent packets then a new API possibly involving reconfiguring the
list bitstream filter can be added knowing the exact requirements.

This ensures it's written at the beginning of a segment in non streaming mode
when segment duration differs from fragment duration.

It's not exclusive for Low Latency streaming. The muxer will serve partial
segments regardless of streaming mode.

This changes the separator character from comma to colon, but since this option
was only added recently I think it should be done for consistency with other
similar options.

this usecase will cause a division by zero trap:
1. dashenc has received one frame
2. os->max_pts and os->start_pts have same value
3. delta between max_pts and start_pts is 0
4. av_rescale_q(0, x, y) returns 0
5. this value is used as denominator in division
6. Bang! -> segfault
this fix checks that max_pts > start_pts.
the fix has been tested and works.

Allows to set an intended target latency while streaming that clients can use
to measure when using low latency mode.

In combination with the streaming option it constrains the value of a few elements,
to prevet clients from buffering too much data before starting presentation.

Implemented as as a frag_duration muxer option and key=value entry in the
adaptation_sets muxer option. It has the same syntax as the seg_duration option.
A new frag_type option is also introduced to select the kind of fragmentation.

Implemented as as a seg_duration key=value entry in the adaptation_sets muxer
option.
It has the same syntax as the global seg_duration option, and has precedence
over it if set.

The Dash muxer uses submuxers and when one such submuxer has been allocated,
it is initially only stored in a temporary variable. Therefore it leaks
if an error happens between the allocation and storing it permanently.
This commit changes this.

From https://aomediacodec.github.io/av1-isobmff/#codecsparam, the parameters
sample entry 4CC, profile, level, tier, and bitDepth are all mandatory fields.
All the other fields are optional, mutually inclusive (all or none).

codecpar->extradata is not going to change between packets. New extradata
is instead propagated using packet side data.
Use ff_alloc_extradata() as well.

The return code is 64bit, so this is more correct, especially in case it
actually would be a file of such large size
