Stop forcing all non-SOCKSPorts to prefer IPv6 exit connections.
Instead, prefer IPv6 connections by default, but allow users to change
their configs using the "NoPreferIPv6" port flag.
Fixes bug 33608; bugfix on 0.4.3.1-alpha.
To run this, say something like
TOR_DEVTOOL_DIR=~/bin scripts/git/git-install-tools.sh all
To see what it would do, give it the -n flag.
To get help, give it the -h flag.
When a service can not upload its descriptor(s), we have no logs on why. This
adds logging for each possible reason for each descriptors.
That logging is emitted every second so it is rate limited for each reason and
per descriptor.

For a bridge configured with a pluggable transport, the transport name is
used, with the IP address, for the GeoIP client cache entry.
However, the DoS subsystem was not aware of it and always passing NULL when
doing a lookup into the GeoIP cache.
This resulted in bridges with a PT are never able to apply DoS defenses for
newly created connections.

Allow the "practracker" coding best practices checking script to read
unicode files, when using Python 2.
We made the script use unicode literals in 0.4.3.1-alpha, but didn't
change the codec for opening files.
Fixes bug 33374; bugfix on 0.4.3.1-alpha.
Use bridges+hs-v23 for "make test-network",
rather than using chutney's old default.
This change requires a recent version of chutney,
because the old bridges+hs-v23 did not work.
(See chutney's 33302 for details.)
Closes 28208.
The IPv6 test only runs if IPv6 is available.
Also, explicitly use the bridges+hs-v2 network for the IPv4-only test.
This network was chutney's default as of January 2020.
Closes 33300.
Add test-network-ipv4 and test-network-ipv6 tests to the Makefile.
These tests run the IPv4-only and dual-stack chutney flavours from
test-network-all.
Closes ticket 33280.
Closing these file descriptors can hide sanitiser logs.
Instead, flush the logs before tor exits, using fsync().
Some Windows environments don't have fsync(), so we check
for it at compile time.
Fixes bug 33087; bugfix on 0.4.1.6.
Stop executing the checked-out pre-commit hook from the pre-push hook.
Instead, execute the copy in the user's git dir.
Fixes bug 33284; bugfix on 0.4.1.1-alpha.
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.

Between 042 and 043, the dirauth options were modularized so this merge commit
address this by moving the AuthDirRejectUncompressedRequests to the module
along with a series of accessors.

Authorities were never sending back 503 error code because by design they
should be able to always answer directory requests regardless of bandwidth
capacity.
However, that recently backfired because of a large number of requests from
unknown source using the DirPort that are _not_ getting their 503 code which
overloaded the DirPort leading to the authority to be unable to answer to its
fellow authorities.
This is not a complete solution to the problem but it will help ease off the
load on the authority side by sending back 503 codes *unless* the connection
is from a known relay or an authority.

The "once" flag makes tor_bug_occurred_() say that future instances
of the warning will be suppressed -- but that's not something that
BUG() does. Fixes bug 33095; bugfix on 0.4.1.1-alpha.
When we added the ACTIVE and DORMANT virtual signals, we taught the
signal command to handle them, but we didn't teach SIGNAL event to
report them.
To solve this problem and prevent it from recurring, this patch
revises the implementation of control_event_signal() to use the same
signal_table that handle_control_signal() uses. This way, the two
controller commands can't become out of sync.
Fixes bug 33104; bugfix on 0.4.0.1-alpha.
Fixes bug 32673; bugfix on 0.3.0.4-alpha. We introduced these
checks in ee5471f9aa to help diagnose 21369, but we used "-1"
when "TOR_TLS_ERROR_MISC" would have been correct. Found by opara.
I don't think that this is actually getting triggered in the wild,
but if it were, it could cause nasty behavior: spurious
WANTREAD/WANTWRITE returns have a way of turning into CPU-eating
busy-loops.
We introduced these BUG() checks in b0ddaac074 to prevent a
recurrence of bug 23690. But there's a report of the BUG() message
getting triggered and filling up the disk. Let's change it to
IF_BUG_ONCE().

Stop allowing failures on the Travis CI stem tests job. It looks like
all the stem hangs we were seeing are now fixed, but let's make sure we
see them if they happen again.
Closes ticket 33075.
Make Tor clients tell dual-stack exits that they prefer IPv6
connections.
This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.
Also update the man page, putting all the IP flags in their
non-default forms.
Closes ticket 32637.
* ticket 32695 removed networkstatus_consensus_has_ipv6(),
