rework message signing options
...
Previously, there was no non-breaking upgrade path to enable message signing by
default while still providing a way to disable it. This patch breaks the options
into:
1. WithMessageSigning - actually enable message signing.
2. WithStrictSignatureVerification - enforce strict signature verification.
3. WithMessageAuthor - set the message author (independent of signing).
Now, users can explicitly set all three options and any changes we make to the
defaults will never override these explicit settings.
This patch *also* enables *signing* by default but not strict signature
verification. We obviously can't enable verification by default yet but I see no
reason not to enable signing. Basically, we're either hurting performance or
security by default. Security issues are generally only noticed once it's too
late. Performance issues can be caught ahead of time.

this allows us to avoid revalidating messages, either because they were concurrently
received or were previously rejected by the validator.
also allows us to filter invalid messages from gossip.
