Filippo Valsorda d88d91e32e crypto/ecdh: new package
We use crypto/internal/edwards25519/field to implement X25519 directly,
so that golang.org/x/crypto/curve25519 can be dropped from the src
module dependencies, and eventually replaced with a crypto/ecdh wrapper,
removing the need to keep golang.org/x/crypto/curve25519/internal/field
in sync with crypto/internal/edwards25519/field.

In crypto/internal/nistec, we add BytesX to serialize only the x
coordinate, which we'll need for the horrible ECDSA x-coord-to-scalar
operation, too.

In crypto/tls, we replace the ECDHE implementation with crypto/ecdh,
dropping the X25519 special cases and related scaffolding.

Finally, FINALLY, we deprecate the ~white whale~ big.Int-based APIs of
the crypto/elliptic package.   •_•)   ( •_•)>⌐■-■   (⌐■_■)
