In the animation filtering code, avoid passing `bDopesheet *ads` as a
separate parameter. Instead, pass `bAnimContext *ac`. This already
contains the same pointer. Some carefully placed asserts help to
verify that these pointers were indeed the same.
Not only do I think this approach is cleaner, it is a necessary step
for upcoming PRs #123187 and #122672. Those will need a `Main *bmain`
pointer, which is already available in the `bAnimContext` struct.
Mostly this is just dumb search & replace.
- `ads` → `ac->ads`
- `bDopeSheet *ads` parameter → remove, and add `bAnimContext *ac`
parameter if necessary. That parameter should be the first parameter
of the function.
- Unused `ads` parameter translates to unused `ac` parameter. Chances
are, that parameter will be necessary for the `Main *bmain` anyway.
No functional changes.
