Improved the dht msg history storage.

- specify how long we store for.
 - cleanup old msgs.
 - improve printing of history.
 - add timeline storage as well.
 - disabled by default, enable USE_HISTORY in bdnode.c

There appears to be a bug related to copying bdId's around.
Some of the bootstrap ids are malformed, and this crashes rs.
