7f39656b4a Apply the Elligator map twice to ensure a uniform distribution 
As noted in the Decaf paper, mapping twice and adding the results ensures a
uniform distribution over the group.  This changes our random point and
hash-to-point functions to do this, matching the Sage script.

c5fcc6602d Fix build for AVX2 backend. 
A missing import of the Borrow trait caused the build to break with the
"yolocrypto" feature enabled; this was't caught by CI because the CI machine
that Travis used didn't have AVX2, so the code was never built.

This commit adds the missing import and changes `std` to `core` so that the
AVX2 backend builds with no_std, but this isn't tested and is, actually,
"yolocrypto".

70f06338f9 Remove docs.rs 
docs.rs won't be the authoritative source for docs any more. Also, it won't build our docs properly, because the nightly Rust it uses is too old to support stuff like markdown-included-in-docs :(

0f185d3e28 Generalize trait bounds on multiscalar multiplication. 
This allows iterators returning either &Scalars or Scalars, so that it's
possible to use map() and friends to adjust scalars as they're being fed into
the multiscalar multiplication.

6748dddb96 Simplify and optimize Montgomery code. 
The `MontgomeryPoint` struct is now a point on the Kummer line of the Montgomery curve.

The `ProjectivePoint` struct is made private, since its only purpose is
internal to the Montgomery ladder.

The Montgomery ladder takes affine input, making it faster, and produces affine output.

The Edwards-Montgomery correspondence is simplified.

d3a8ee0d7b Remove BASEPOINT_ORDER_MINUS_* constants 
These were originally added in 32da4c7d50
to implement Scalar negation in terms of multiply-add.

But we have a full implementation of scalar arithmetic now, so it's not
necessary to keep the constants around.
