calls in the same place.

9a69c24150 Do not use strcmp() to compare an http authenticator to its expected value
This fixes a side-channel attack on the (fortunately unused!)

a74905cea4 We allow IPv6 connections, don't use sockaddr_in with getsockname
This fixes client_check_address_changed to work better with IPv6 Tor
clients, and prevents them from spewing errors. Fix for ticket 5537.

cc35157805 Twiddle ROUTER_{MAX_COSMETIC_TIME_DIFFERENCE,MAX_AGE_TO_PUBLISH}
This is ticket 2479. Roger's original explanation was:

   We have a series of bugs where relays publish a descriptor within
   12 hours of their last descriptor, but the authorities drop it
   because it's not different "enough" from the last one and it's
   too close to the last one.

   The original goal of this idea was to a) reduce the number of new
   descriptors authorities accept (and thus have to store) and b)
   reduce the total number of descriptors that clients and mirrors
   fetch. It's a defense against bugs where relays publish a new
   descriptor every minute.

   Now that we're putting out one consensus per hour, we're doing
   better at the total damage that can be caused by 'b'.

   There are broader-scale design changes that would help here, and
   we've had a trac entry open for years about how relays should
   recognize that they're not in the consensus, or recognize when
   their publish failed, and republish sooner.

   In the mean time, I think we should change some of the parameters
   to make the problem less painful.

56e0959d2a Have tor_parse_*long functions check for negative bases
One of our unit tests checks that they behave correctly (giving an
error) when the base is negative.  But there isn't a guarantee that
strtol and friends actually handle negative bases correctly.

Found by Coverity Scan; fix for CID 504.

88caa552cc Fix a couple of "unused assigned value" warnings in parse_config tests
Coverity doesn't like the fact that we were storing the value of
parse_config_line_from_str() but not checking it in a couple of
cases.

Fixes CID 505 and 506.

ab3197c059 Remove a couple redundant NULL-checks before crypto_cipher_free
Calling crypto_cipher_free(NULL) is always safe, since (by
convention) all of our xyz_free() functions treat xyz_free(NULL) as
a no-op.

Flagged by coverity scan; fixes CID 508 and 509.

491ffa540f Move router lookup to _after_ we assert that its argument is set
A previous commit in the 5527 branch had moved
router_get_mutable_by_digest(digest_rcvd) to happen before we did
tor_assert(digest_rcvd), which would have defeated the purpose of
the assert.

3031def726 checking "same addr/port but with nonmatching keys" is obsolete
Specifically, I believe it dates back to when extend cells had address:port
but no digest in them. The special edge case is certainly not worth the
complexity these days.

734fad4103 Make relays handle an address suggestion from a directory server giving an IPv6 address.
last_guessed_ip becomes a tor_addr_t.

Most parts of router_new_address_suggestion() learns
about IPv6 (resolve_my_address() is still IPv4 only).

d20c6d2a37 Keep separate time-to-downloads for each consensus flavor
This is a fix for bug 4011, where if we have a recent ns consensus we
won't even try fetching a microdesc consensus.  Fix on 0.2.3.1-alpha,
I believe.
