- As initalized, `EliasFanoReader` and `BitVectorReader` held a value of `0`, thus if `0` is present in the list `skipTo(0)` would not update the position to `0`, as it happens with any other `skipTo(<first element>)`. This fixes `jumpTo` accordingly.
- `jump(i + 1)` would go at position `i`. Now `reader.jump(i)`'s postcondition is `reader.position() == i`.
- It is now illegal to retrieve `value()` from a reader in an out-of-bounds position (before-the-begin or past-the-end). Validity of a reader can be checked with `valid()`.

folly: specialise makeFutureWith for functions returning futures

Summary: makeFutureWith executes a function and returns a future containing

for the case when the function returns some type Future<T>. Instead

on the future that the function returned, which may or may not have
a value set at this time. In case the function throws,
makeFutureWith returns a Future<T> containing the exception.

  auto f1 = makeFutureWith(func);
  auto f2 = makeFuture().then(func);

(Wangle) Align lambdaBuf_

We use `lambdaBuf_` to store a type of up to `lambdaBufSize`, so aligning it to that should always be safe.
