Currently, ffmpeg inserts scale filter by default in the filter graph
to force the whole decoded stream to scale into the same size with the
first frame. It's not quite make sense in resolution changing cases if
user wants the rawvideo without any scale.
Using autoscale/noautoscale to indicate
Add docs for autoscale/noautoscale.
Update information for autorotate according to ffplay.

Add support for max frame size:
- max_frame_size (bytes) to indicate the max allowed size for frame.
If the frame size exceeds the limitation, encoder will to control the frame

- MFS_NUM_PASSES to indicate number of passes for QP adjust.

This seems reasonable to me, but I have not been involved in any rtp code.
The commit message is maybe a bit on the verbose side, but I don't have any
strong opinion.

Up until now, when performing a SEEK_END seek, the subfile protocol
ignored the desired position (relative to EOF) and used the current
absolute offset in the input file instead.
And when performing a SEEK_CUR seek, the current position has been
ignored.

it is expected that there will be more files to support native mode,
so put all the dnn codes under libavfilter/dnn
The main change of this patch is to move the file location, see below:
modified: libavfilter/Makefile
new file: libavfilter/dnn/Makefile
renamed:
the reason to add this layer first is that vf_sr uses it in its
tensorflow model, and the next plan is to update the python script
to convert tf.pad into native model.
