Bump secp256k1-sys version to 0.8.1

We are ready to release a new minor version of `secp256k1-sys`, in order to do so we must make change the symbol names to reflect the new version as well as the usual changelog and version bump. In preparation for releasing `secp256k1-sys` v0.8.1 do: - Rename symbols to from `0_8_0` -> `0_8_1`, done mechanically (search and replace) - Add changes log notes (includes changelog entry for 0.8.0) - Bump `secp256k1-sys` crate version 0.8.0 -> 0.8.1, justified because we have added a new public function.
