Previously, "--list-fingerprint --quiet" was an error. Now, the
handler for optional arguments to "--list-fingerprint" can tell that
"--quiet" is a flag, not an argument.
This only affects flags that take an _optional_ argument, so you can
still put your torrc file in a location starting with "-".
Closes#40223.
The "-static" compile flag was set globally which means that all autoconf test
were attempting to be built statically and lead to failures of detecting
OpenSSL libraries and others.
This commit adds this flag only to the "tor" binary build.
There is also a fix on where to find libevent.a since it is using libtool, it
is in .libs/.
At this commit, there are still warnings being emitted that informs the user
that the built binary must still be linked dynamically with glibc.
Fixes#40111

The Python code is such a nice addition to the documentation and the C
code for better understanding of onion v3 address generation. Straight
to the point and easy to understand.
Unfortunately it did not work with my distribution's Python version. I
have adjusted the code to support Python 3.8 (tested with 3.8.6) and
to still be compatible with Python 2.
Currently Tor fails with the following error:
src/test/test_stats.c: In function ‘test_rephist_v3_onions’:
src/test/test_stats.c:527:22: error: overflow in implicit constant conversion [-Werror=overflow]
update_approx_time(10101010101);
This patch changes the constant passed to update_approx_time() to avoid
the overflow in the implicit conversion.
See: tor#40199
The rest of rephist.c is doing the same kind of unsigned casting. For example
see rep_hist_format_buffer_stats() and rep_hist_format_exit_stats().
The previous switch to %ld made Appveyor fail:

When sending the stream level SENDME, it is possible the cirucit was marked
for close or any other failures that can occur. These events can occur
naturally.

The function in charge of removing duplicate ORPorts from our configured ports
was skipping all non ORPorts port but only for the outer loop thus resulting
in comparing an ORPort with a non-ORPort which lead to problems.
For example, tor configured with the following would fail:
ORPort auto
DirPort auto
Both end up being the same configuration except that one is a OR listener and
one is a Dir listener. Thus because of the missing check in the inner loop,
they looked exactly the same and thus one is removed.

First, this commit moves the launch_dummy_circuit_as_needed() function into
relay_find_addr.c and renames it to relay_addr_learn_from_dirauth(). This is
an attempt to centralize anything relate with address discovery in the right
module.
Second, when building a descriptor and we fail to discover our address,
immediately launch a dummy circuit to an authority in an attempt to learn our
descriptor.
It is still only done every 20 minutes even though the descriptor build is
done every minute. We ought to avoid load on the authority and if we can't
learn in the first place our address from them, chances are more things are
wrong.

Regularly, tor looks if its IP has changed. It does the entire auto discovery
process again. However, it is possible that it does not find anything.
Instead of thinking the IP changed to an unknown address, look at our cache
and see if that value has changed.
The reason for this is because if tor gets its address as a suggestion from a
directory authority, it is because the auto discovery failed and thus that
address should be consider for the IP change check.

Tor now can learn its address from a NETINFO cell coming from an authority.
Thus, instead from launching a dummy descriptor fetch to learn the address
from the directory response (unauthenticated), we simply now launch a one-hop
testing circuit.
