Merge pull request #293 from dalek-cryptography/remove-build-rs 
Remove build.rs constants generation.

574217694e Remove build.rs. 
This was more useful at the time when we were determining, e.g., optimal lookup
table sizes and could regenerate them more easily, but it came at a massive
complexity cost.  It also meant that we were unable to implement backend
autoselection.  This commit removes the `build.rs` entirely.  In the future, a
different `build.rs` could be added that auto-selects a backend, but it seems
like the current default-u64 setup has been working fine.

Add an optimisation to succeed fast for scalars whose 4th MSB is unset. 
This is only done during signature verification.

Rust fixes for some clippy warnings 
Clippy lints with instances in the project but NOT applied here, since they seem consistently at odds with the projects' style:
- [unreadable literal](https://rust-lang.github.io/rust-clippy/master/#unreadable_literal)
- [cast lossless](https://rust-lang.github.io/rust-clippy/master/#cast_lossless)
- [assign op pattern](https://rust-lang.github.io/rust-clippy/master/#assign_op_pattern)

Implement stricter scalar malleability checking for signatures. 
Previously, we were checking that the highest 3 bits were unset, which still
leaves 2^253 - 2^252 + 27742317777372353535851937790883648493 potential scalars
for the `s` component of a signature which are not strictly mod \ell.

This change fixes that.

Note: This change makes ed25519-dalek incompatible with ed25519-donna in that
some signatures produced by donna will be verifiable by donna but NOT VERIFIABLE
by dalek.  On the other hand, libsodium exports a -DED25519_COMPAT feature,
which when enabled, means it is compatible with dalek with the
`legacy_compatibility` feature disabled.  Otherwise, libsodium's behaviour is
identical to the behaviour enabled by default in this patch.

90baabe50b Ensure Scalar Add and Sub produce canonical results. 
Closes #238.

This issue was discovered independently by both Jack "str4d" Grigg
(issue #238), who noted that reduction was not performed on addition, and
Laurent Grémy & Nicolas Surbayrole of Quarkslab, who noted that it was possible
to cause an overflow and compute incorrect results.
