This series adds the ref-in-want feature which was originally proposed by Jonathan Tan (https://public-inbox.org/git/cover.1485381677.git.jonathanta...@google.com/).
Back when ref-in-want was first discussed it was decided that we should first solve the issue of moving to a new wire format and find a way to limit the ref-advertisement before moving forward with ref-in-want. Now that protocol version 2 is a reality, and that refs can be filtered on the server side, we can revisit ref-in-want. This version of ref-in-want is a bit more restrictive than what Jonathan originally proposed (only full ref names are allowed instead of globs and OIDs), but it is meant to accomplish the same goal (solve the issues of refs changing during negotiation).
