On some windows builds, time_t is 64 bits but long is not.  This is
causing appveyor builds to fail.

Also, one of our uses of labs() on time_t was logically incorrect:
it was telling us to accept NETINFO cells up to three minutes
_before_ the message they were responding to, which doesn't make
sense.

This patch adds a time_abs() function that we should eventually move
to intmath.h or something.  For now, though, it will make merges
easier to have it file-local in channeltls.c.

Fixes bug 31343; bugfix on 0.2.4.4-alpha.

Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc
in December 2018 (of which ~122 were still functional), with a
list of 148 fallbacks (70 new, 78 existing, 79 removed) generated
in June 2019.

Closes ticket 28795.

Note that we created extra lists from DE and US, but they didn't add
any more fallbacks when we tried to merge them.

Update the fallback directory mirrors by merging the current list with:
fallback_dirs_2019-06-28-08-58-39_AU_f0437a39ddbc8459.inc

Part of 28795, see that ticket for logs.

Update the fallback directory mirrors by replacing the old list with:
fallback_dirs_2019-06-25-11-49-10_AU_a37adb956fbb5cd2.inc

We need to keep the gcno files, because they are created at compile time.

When classifying a client's selection of TLS ciphers, if the client
ciphers are not yet available, do not cache the result. Previously,
we had cached the unavailability of the cipher list and never looked
again, which in turn led us to assume that the client only supported
the ancient V1 link protocol.  This, in turn, was causing Stem
integration tests to stall in some cases.  Fixes bug 30021; bugfix
on 0.2.4.8-alpha.

And fix a comment.

Otherwise, "make check-changes" will complain when we backport the change.

We need a recent test-network.sh to use new chutney features in CI.

Fixes bug 29703; bugfix on 0.2.9.1-alpha.

Since we have moved coveralls to the script target the entire build will
now fail if coveralls fail. We handle it more gracefully by echo'ing the
failure instead of doing a hard-failure.

This should ensure that GCDA files are never entering the cache of
Travis CI.

Already merged to 0.4.0 and later in tor-github/pr/776.
Backported to 0.2.9 and later with minor comment changes.

Part of 29706.

Allow connections to single onion services to remain idle without being
disconnected.

Relays acting as rendezvous points for single onion services were
mistakenly closing idle established rendezvous circuits after 60 seconds,
thinking that they are unused directory-fetching circuits that had served
their purpose.

Fixes bug 29665; bugfix on 0.2.1.26.

Stop leaking parts of the shared random state in the shared-random unit
tests. The previous fix in 29599 was incomplete.

Fixes bug 29706; bugfix on 0.2.9.1-alpha.

Turns out that when reloading a tor configured with hidden service(s), we
weren't copying all the needed information between the old service object to
the new one.

For instance, the desc_is_dirty timestamp wasn't which could lead to the
service uploading its descriptor much later than it would need to.

The replaycache wasn't also moved over and some intro point information as
well.

Prior to #23100, we were not counting HS circuit build times in our
calculation of the timeout. This could lead to a condition where our timeout
was set too low, based on non HS circuit build times, and then we would
abandon all HS circuits, storing no valid timeouts in the histogram.

This commit avoids the assert.

Stop leaking parts of the shared random state in the shared-random unit
tests.

malloc_options needs to be declared extern (and declaring it extern
means we need to initialize it separately)

Many of these files cause check-changes to fail, which will be a
long-term problem as we continue to support 0.2.9.

Stop logging "Tried to establish rendezvous on non-OR circuit..." as
a warning. Instead, log it as a protocol warning, because there is
nothing that relay operators can do to fix it.
