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.

Tests for wire protocol version 2 exchange.
Tests in this file should be folded into existing tests once protocol
v2 has enough features that it can be enabled via #testcase in existing
tests.
