Jack Grigg 232f0a50b8 ff: Rework BitIterator to work with both u8 and u64 limb sizes 
This enables BitIterator to be used with both the byte encoding and limb
representation of scalars.
 2020-04-23 16:23:24 +12:00
Jack Grigg fd79de5408 ff: Add PrimeField: From<u64> constraint 2020-04-23 16:23:24 +12:00
Jack Grigg b6457a905b ff: Move pow_vartime into a trait that is generic over the limb size 
The trait is implemented by default for u8 and u64, allowing pow_vartime
to be used with both the byte encoding and limb representation of field
elements.

Jack Grigg 69c60530d4 group: Rewrite wNAF to remove dependency on ff::PrimeFieldRepr

Constant-time field inversion 
WARNING: THIS IS NOT ACTUALLY CONSTANT TIME YET!

The jubjub and bls12_381 crates will replace our constant-time usages,
but we NEED to fix ff_derive because other users will expect it to
implement the Field trait correctly.
