Rename and refactor several F-curve key manipulation functions, and move them from `editors` to `blenkernel`. The functions formerly known as `delete_fcurve_key`, `delete_fcurve_keys`, and `clear_fcurve_keys` have been moved from `ED_keyframes_edit.h` to `BKE_fcurve.h` and have been renamed according to hierarchical naming rules. Below is a table of the naming changes. | From | To | | -- | -- | | `delete_fcurve_key(fcu, index, do_recalc)` | `BKE_fcurve_delete_key(fcu, index)` | | `delete_fcurve_keys(fcu)` | `BKE_fcurve_delete_keys_selected(fcu)` | | `clear_fcurve_keys(fcu)` | `BKE_fcurve_delete_keys_all(fcu)` | | `calchandles_fcurve()` | `BKE_fcurve_handles_recalc()` | | `calchandles_fcurve_ex()`| `BKE_fcurve_handles_recalc_ex()` | The function formerly known as `delete_fcurve_key` no longer takes a `do_fast` parameter, which determined whether or not to call `calchandles_fcurve`. Now, the responsibility is on the caller to run the new `BKE_fcurve_handles_recalc` function if they have want to recalculate the handles. In addition, there is now a new static private function called `fcurve_bezt_free` which sets the key count to zero and frees the key array. This function is now used in couple of instances of functionally equivalent code. Note that `BKE_fcurve_delete_keys_all` is just a wrapper around `fcurve_bezt_free`. This change was initially spurred by the fact that `delete_fcurve_keys` was improperly named; this was a good opportunity to fix the location and naming of a few of these functions.
