openpgp: Rename PacketParser::{set_,}encrypted to processed.

  - Convert `encrypted` to `processed`.

  - Since `set_encrypted` is internal API it was directly renamed without
    forwarder stub.

  - `encrypted()` is public API thus the old function is converted to a
    forwarder of the negation of `processed()`.

  - `unprocessed()` marked as deprecated.

  - Update docs and NEWS file.

  - Fixes #845.
