When logging TLS certificate and identity-related errors, scrub IP addresses for incoming connections, and distinguish between incoming and outgoing connections in log messages. Backport candidate.

Fix an XXXX012 in routerlist.c: when we do not have enough networkstatuses to launch router requests, do not launch router requests. Backport candidate.
svn:r9388
Implement SOCKS_BAD_HOSTNAME status event. Defer remaining status events. Clean up control-spec.txt a little, and fill in recommendations for events.

Apparently, the OpenBSD linker thinks it knows C better than I do, and gets to call me names for having strcat and strcpy and sprintf in my code--whether I use them safely or not. All right, OpenBSD. You win... this round.

Tidy up ORCONN reason patch from Mike Perry. Changes: make some of the handling of TLS error codes less error prone. Enforce house style wrt spaces. Make it compile with --enable-gcc-warnings. Only set or_conn->tls_error in the case of an actual error. Add a changelog entry.

handshake to finish. Previously we would let them sit around for
days, if the connecting application didn't close them either.
Also take this opportunity to refactor a duplicate bit of circuituse.c.
And change the semantics of SocksTimeout slightly, but I think it'll
be ok.

Check addresses for rfc953-saneness at exit too, and give a PROTOCOL_WARN when they fail. Also provide a mechanism to override this, so blossom can have its @@##$$^.whatever.exit hostnames if it wants.
svn:r9336
Clear untrusted networkstatuses after 10 days too. (This is not a terribly awful bug, since we would only ever retain 16 of them, but it still might be nice to backport.) Resolves part A of bug 372.
svn:r9324
Implement a control status event for bad libevent version/method combos. Warn that libevent <1.1 with select() is needlessly slow. Reply to comment.
svn:r9284
Fix computation of total_exit_bandwidth; this will cause exits not to get recommended as guards if the total exit bandwidth if they constitute less than a third of total available bandwidth. There may be problems here with flapping; lets see if they occur in practice.
svn:r9281
Re-enable warning when we resolve an already resolved address. We only warn here now if the address is not a testing address. Also, refactor out a function to check whether an address is used for testing.
svn:r9280
Add (and specify) a BadDirectory flag to networkstatuses, so authorities can tell clients that some caches are broken. Also, implement an as-yet-unused function to estimate how many bytes will be sent on a directory connection.
svn:r9255
Close any directory connection on which we have received 10MB or more of data. This prevents a malicious directory cache from running us out of memory by spooling an infinite amount of data. (Not a terribly good attack, but hey, every one helps.)
svn:r9210
Count TLS bytes accurately: previously, we counted only the number of bytes read or transmitted via tls, not the number of extra bytes used to do so. This has been a lonstanding wart. The fix "Works for me".
svn:r9207
If we only have a single nameserver, raise the threshold to decide that the nameserver is dead. (Another fumbling attempt to do something about bug 326.)
