merge with stable

There were a handful of merge conflicts in the wire protocol code due
to significant refactoring in default. When resolving the conflicts,
I tried to produce the minimal number of changes to make the incoming
security patches work with the new code.

I will send some follow-up commits to get the security patches better
integrated into default.
