Comment(by nickm):

 The check in connection_bytes_decrement is wrong; CONN_TYPE_DIR is not
 only directory request that we're answering, but also directory requests
 that we're making.

 The calculation of "len" in rep_hist_get_bandwidth_lines assumed that the
 longest identifier it cared about was write-history; dirreq-write-history
 is longer.  Also, are there any tors left that still care about getting
 "opt" ?  I'm pretty sure "opt" is unnecessary now that Tor 0.1.2.5 and
 earlier are dead, so we might as well remove it in a followup patch.
