Rename reduce32 to reduce and have it return its result.
...
This means that all FieldElement32x4 operations return values, vs mutating interior state.

Add MultiscalarMul and VartimeMultiscalarMul traits.
...
These traits have the same interface, but with different names, so that it's
not possible to use them interchangeably. (Constant-time and variable-time
routines should not be used interchangeably).
This commit changes the external API to use these traits, replacing
```
edwards::multiscalar_mul
edwards::vartime::multiscalar_mul
```
with
```
EdwardsPoint::multiscalar_mul (as an impl)
EdwardsPoint::vartime_multiscalar_mul (as an impl)
```
and similarly for Ristretto.
Refactoring the backend is for a later commit.
Multiscalar multiplication with precomputation is for a later commit.
The `edwards::vartime` module is retained since it's used for
`vartime_double_base_scalar_mul`.
It should be subsumed into the precomputation API in a later commit.

Rework backend selection code.
...
Each backend can now be selected by an individual feature:
- `u32_backend` for `backend::u32`;
- `u64_backend` for `backend::u64`;
- `avx2_backend` for `backend::avx2`;
The `u64_backend` is selected by default, since most people use X64 and we have
no way to select based on target (see discussion in #126 ). However, these
changes mean that it is possible to select the backend explicitly, and if we
had the ability to select target-default features, we could do so easily.
