Fixes division by 0
This is similar to how avg_frame_rate is checked elsewhere

This way, in case of bit rate not being set, max_bitrate will be
used instead. This enables, for example, re-using max_bitrate
information from the input or doing transcoding with a rate
control mode that is not bit rate based.

Sometimes it's useful to be able to define the exact track numbers in
the generated track, instead of always beginning at track id 1. Using
the option use_stream_ids_as_track_ids now copies the use stream ids
to track ids. Dynamically generated tracks (ie. tmcd) have their track
numbers defined as continuing from the highest numbered stream id.

It's a small and simple function that can be inlined.
This removes one private symbol and should reduce object dependencies with the next
major bump

When writing a fragmented file, we by default write an index pointing
to all the fragments at the end of the file. This causes constantly
increasing memory usage during the muxing. For live streams, the
index might not be useful at all.
A similar fragment index is written (but at the start of the file) if
the global_sidx flag is set. If ism_lookahead is set, we need to keep
data about the last ism_lookahead+1 fragments.
If no fragment index is to be written, we don't need to store information
about all fragments, avoiding increasing the memory consumption
linearly with the muxing runtime.
This fixes out of memory situations with long live mp4 streams.

Add -movflags use_metadata_tags to the mov muxer. This will cause
the muxer to write all metadata to the file in the keys and mtda
atoms.

The second one is not explicitly needed, as res is not reset, but it is there
for consistency.

This was missed in e1eb0fc960, when ff_interleaved_peek was
changed to include const during the evolution of the patch.

As long as caller only writes packets using av_interleaved_write_frame
with no manual flushing, this should allow us to always have accurate
durations at the end of fragments, since there should be at least
one queued packet in each stream (except for the stream where the
current packet is being written, but if the muxer itself does the
cutting of fragments, it also has info about the next packet for that
stream).

This codepath isn't quite as bad as it used to sound, if fragments
are cut automatically at video packets.
