There are many problems of current qsv trellis option:
1. Duplicated with AVCodecContext definition
2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17
   Currently Without MSDK API checking thus may cause compilation issue.
3. user is inclined to enable trellis when set "-trellis 1", but
   actually it is to disable since MFX_TRELLIS_OFF is equal to 1.
4. It is too complex for user to enable trellis for every frame(I/P/B).

Just simply remove the private option, and switch to the AVCodecContext
definition. Compatibility should not a big problem (except can't exact map)
since the option name is same as AVCodecContext.

The lensfun filter wraps the lensfun library which performs
transformations on videos to correct for lens distortion. Often this
results in areas in the input being mapped to areas that fall outside
the boundaries of the output. The library has a parameter called scale
which is a scale factor applied to the output video. By decreasing it it
is possible to regain the areas of the video which would otherwise have
been lost. There is a special value of 0 which indicates that the
library should automatically determine a scale factor that results in
the output frame being filled (i.e. little or no black/unmapped areas).

This patch adds a corresponding scale option to the lensfun filter which
is passed through to the library. The existing behaviour of using the
automatic value of 0 is retained as the default behaviour, while other
values will be passed through to the library.
