Split `BKE_fcurve_blend_write(writer, listbase)` into two functions: - `BKE_fcurve_blend_write_data(writer, fcurve)` for the data of a single F-Curve, and - `BKE_fcurve_blend_write_listbase(writer, listbase)` for writing a list of F-Curves. And the same for `BKE_fcurve_blend_read_data()`. This is necessary for the upcoming Animation data-block, which will store F-Curves as arrays instead of `ListBase`s. No functional changes.
