It turns out that 9 years ago, we stopped appending data into stats file and
rather overwrite everytime we have new stats (see commit
a6a127c833)
The load_stats_file() function was still thinking that we could have the same
line many times in the file which turns out to be false since 9 years ago.
However, that did not cause problem until IPv6 connection stats came along
which introduced a new line in conn-stats: "ipv6-conn-bi-direct ...".
Before, that file contained a single line starting with the tag
"conn-bi-direct". That very tag appears also in the IPv6 tag (see above) so
the load_stats_file() function would consider that the IPv6 line as the last
tag to be appeneded to the file and fail to report the line above (for IPv4).
It would actually truncate the IPv6 line and report it (removing the "ipv6-"
part).
In other words, "conn-bi-direct" was not reported and instead
"ipv6-conn-bi-direct" was used without the "ipv6-" part.
This commit refactors the entire function so that now it looks for a
"timestamp tag" to validate and then if everything is fine, returns the entire
content of the file. The refactor simplifies the function, adds logging in
case of failures and modernize it in terms of coding standard.
Unit tests are also added that makes sure the loaded content matches the
entire file if timestamp validation passes.

When making sure we have a Bridge line with a ClientTransportPlugin, we
now check in the managed proxy list and so we can catch any missing
ClientTransportPlugin for a Bridge line.

Generates the compile_commands.json file using the "bear" application so the

Previously, our code would send back an error if the socks5 request
parser said anything but DONE. But there are other non-error cases,
like TRUNCATED: we shouldn't send back errors for them.
This patch lowers the responsibility for setting the error message
into the parsing code, since the actual type of the error message
will depend on what problem was encountered.
Fixes bug 40190; bugfix on 0.3.5.1-alpha.
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.

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.

This changes the behaviour of `tor --version` in such a way.
```console
src/app/tor --version
Tor version 0.4.5.1-alpha-dev (git-46ccde66a97d7985).
Tor is running on Linux with Libevent 2.1.12-stable, OpenSSL 1.1.1h, Zlib 1.2.11, Liblzma 5.2.4, Libzstd 1.4.5 and Glibc 2.31 as libc.
Tor compiled with GCC version 10.2.0
