bookmark: use the 'bookmarks' bundle2 part to push bookmark update (issue5165) We use the new binary parts we introduced earlier to exchange bookmark. The payload is a bit more compact since we use binary and the length of bookmarks is no longer constrained to 255. .. fix:: Issue 5165 Bookmark, whose name is longer than 255, can again be exchanged again between 4.4+ client and servers.
