openpgp: Pass a timestamp to the KeyIter instead of each filter.

  - KeyIter::revoked and KeyIter::key_flags (and its variants) didn't
    take a time stamp so they could only be used for filtering keys
    based on their current state, not their state at some time in the
    past.  Adding a time stamp to each of the filters would have fixed
    the problem, but it would have made the interface ugly: callers
    always want the same time stamp for all filters.

  - Split KeyIter into two structures: a KeyIter and a ValidKeyIter.

  - Add KeyIter::policy.  It takes a time stamp, which is then used
    for filters like `alive` and `revoked`, and it returns a
    ValidKeyIter, which exposes filters that require a time stamp.
