Make FieldElement limbs private to the curve25519-dalek crate.
...
Limbs are no longer accessible outside of the curve25519-dalek crate.
If you were relying on this behaviour, first you probably shouldn't be
doing that, second please contact us so we can determine the best way
forward for your use case.

Remove direct compression methods between points in curve models.
...
compress_edwards() is now named compress() and works only on points
which are in Edwards form. Similarly, compress_montgomery() is now
also called compress(), and it only works on point already in
Mongomery form.
To switch between forms, use to_montgomery().
Conversion from Montgomery directly to Edwards is not yet implemented.
* CHANGE the API requested in
https://github.com/isislovecruft/curve25519-dalek/issues/47 ,
hopefully for the better.

Use the addition chain from

In my benchmarking, this consistently runs at least 20% faster.
