Most operations where strips are duplicated use `SEQ_animation` API,
which handles keyframe animation. Now drivers are handled as well.
When group of strips is duplicated and driver references other strip,
it will still reference original strip. However, this is much better,
than previous behavior, when strip duplication results in "transfer" of
driver from original strip to duplicated one.
Fixes T104141
Since e49bf4019b, animation is handled explicitly. Split operator
wasn't updated.
Re-use backup-duplicate-restore animation functions, that other
operators use for splitting.
Use a shorter/simpler license convention, stops the header taking so
much space.

Ref D14069
- Move functions that handle animation to own file - `animation.c`
- Refactor `SEQ_offset_animdata` and `SEQ_free_animdata` functions
- Add function `SEQ_fcurves_by_strip_get` to provide more granular
and explicit way for operators to handle animation
- Remove function `SEQ_dupe_animdata`, do curve duplication explicitly
in operator code, which makes more sense to do. Further this function
was also used for renaming strips which makes no sense.
- Refactor usage of function `SEQ_free_animdata` and remove XXX comment.
Now this functiuon is no longer called when `Sequence` data is freed
implicitly, it is done explicitly in high level function
`SEQ_edit_remove_flagged_sequences`
