narrow: don't hexify paths and double-hexify known nodes on wire (BC)...

narrow: don't hexify paths and double-hexify known nodes on wire (BC) It isn't obvious, but wireprototypes.encodelist() is meant only for binary nodeids. So when we used it for encoding hex nodeids and paths, the encoded result was surprising and hard to read. This patch changes the encoding to make the list of paths a comma-separated list and the list of common nodes to be a encodelist()-encoded list of binary nodeids (so the result is just singly-hexified nodeids). This is clearly a breaking change, but the feature is experimental and we're not aware of anyone running a server using this command yet. Differential Revision: https://phab.mercurial-scm.org/D6851
