Previously the duration was sometimes wrong, this addition
limits the value and improves which frames are choosen when
reducing the frame rate

This is a bit ugly as it attempts to keep most of the computation
in integers before the double based fps code. The use of integers
is to reduce the chances of rounding differences between platforms
Previously the timestamp was rounded to the encoder timebase
before being converted back to double precision which could cause loss
of precision

The format is now:
-bsf:X filter1[=opt1=str1/opt2=str2],filter2
ie the parameters are appended after the filter name using '='. As ','
has been reserved already for the list of filters, '/' is just an
example of token separation for now, but that could become part of the
API to avoid each bsf using its own tokenization.
The proper solution would be using AVOption, but this is overkill for now.

The issue is that, when the main packet data buffer is changed, streamcopy
uses a temporary new packet to store that buffer, frees the old packet, and
replace it with the new packet.
However, in doing so, it forgets about the side data, which gets freed, but
is still needed and referenced. Then, when the packet gets freed again in
the normal code path, it attempts to free its side data which has already
been freed.
Therefore, simply avoid the first free on side data by removing that side
data from the packet.
Fixes ticket #3773.

Commit fc9c857c introduced deadlock regression when processing too many inputs:
ffmpeg $(seq -f " -f lavfi -i aevalsrc=0:d=%.0f" 70) -vf concat=n=70:v=0:a=1 -f null -
Happens for different number of inputs, depending on available memory size,
overcommit settings, ulimits, etc. Easily noticeable for 32-bit builds,
that exhaust address space allocating 8-10 MB stack for each thread.
Earlier ffmpeg versions exited with unhelpful "Conversion failed!" message.
This patch fixes both problems: it frees the queue to prevent deadlock
and adds a meaningful error message if pthread_create() fails.

With threads the decoder has a delay and will thus have multiple
frames at EOF left in its buffers which will be returned when flushing
the decoder. The code that extracts such frames from the decoder at the
end does not pull frames from the filtergraph, thus when one of these
frames causes the filtergraph to be reinited, the frames still inside
the graph at that point re lost
This commit changes the flushing to be more similar to normal decoding
and 1 frame at a time

Ideally the parser would always set this correctly, but some parsers lac support
