Draft: Bridge APIs for Arti 1.1.0
In this branch I'm starting on a set of draft APIs for bridges and pluggable transports in Arti.
There is a log of uncertainty and TODO
comments.
I estimate that this is about half of the APIs we will need ; the next steps are listed at the bottom of the document.
My apologies for all confusing parts: I have probably forgotten to explain all of my motivations as I wrote this.
I'm hoping for review fronm @eta and @Diziet. Please do not merge as-is.
