exchangev2: fetch and apply bookmarks This is pretty similar to phases data. We collect bookmarks data as we process records. Then at the end we make a call to the bookmarks subsystem to reflect the remote's bookmarks. Like phases, the code for handling bookmarks is vastly simpler than the previous wire protocol code because the server always transfers the full set of bookmarks when bookmarks are requested. We don't have to keep track of whether we requested bookmarks or not. Differential Revision: https://phab.mercurial-scm.org/D4486
