[tor/release-0.2.2] Don't try to build descriptors when router_get_advertised_or_port()==0

commit 0e1fad648d22923d7455b94734df36585b8f624f Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 24 11:55:08 2011 -0400 Don't try to build descriptors when router_get_advertised_or_port()==0 The previous attempt was incomplete: it told us not to publish a descriptor, but didn't stop us from generating one. Now we treat an absent OR port the same as not knowing our address. (This means that when we _do_ get an OR port, we need to mark the descriptor dirty.)

[tor/release-0.2.2] Log descriptions of nodes, not just nicknames.

commit b95dd03e5f6505ce2e78fe34a20bf5e5c970e6eb Author: Nick Mathewson <nickm(a)torproject.org> Date: Sun May 15 21:58:46 2011 -0400 Log descriptions of nodes, not just nicknames. This patch introduces a few new functions in router.c to produce a more helpful description of a node than its nickame, and then tweaks nearly all log messages taking a nickname as an argument to call these functions instead. There are a few cases where I left the old log messages alone: in these cases, the nickname was that of an authority (whose nicknames are useful and unique), or the message already included an identity and/or an address. I might have missed a couple more too.
