Add on-by-default fast crate feature for gating basepoint tables (#251)
* Add on-by-default `fast` crate feature

Disabling the feature reduces overall code size at the cost of
performance, which is useful for e.g. embedded users.

This feature transitively enables the `basepoint-tables` feature in
`curve25519-dalek` where the basepoint tables are actually defined.

* Consolidated a lot of verification code

* Bump `curve25519-dalek`; use `precomputed-tables` feature

The feature name changed in dalek-cryptography/curve25519-dalek#499

Use curve25519-dalek from git; check in Cargo.lock (#260)
Updates to the latest upstream changes in `curve25519-dalek`, including
using the new `EdwardsPoint::mul_base` API.

To keep the build deterministic, this also checks in Cargo.lock, which
pins `curve25519-dalek` to a particular git commit SHA which can be
updated using `cargo update -p curve25519-dalek`.

We can potentially remove `Cargo.lock` again after a crate release.
