[PATCH v3 2/4] cli: expose message-wide crypto status from mime-node

[Daniel Kahn Gillmor]

The mime node context (a per-message context) gains a cryptographic
status object, and the mime_node_t object itself can return a view on
that status to an interested party.

The status is not yet populated, and for now we can keep that view
read-only, so that it can only be populated/modified during MIME tree
traversal.
