lavfi: remove avfilter_null_* from public API on next bump.
...
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

drawtext: add 'fix_bounds' option on coords fixing
...
Before, drawtext filter deliberately altered given text coordinates if
text didn't fully fit on the picture. This breaks the use case of
scrolling large text, e.g. movie closing credits.
Add 'fix_bounds', to make it usable in such cases (by setting its value to 0).
Default behavior is not changed, and non-fitting text coords are fixed.

It's a hack which was created to allow for multiple options with
