* We no longer call this an optional method
* We document that it returns the real address, not a canonical one.
* We have it try harder if the real address hasn't been set yet.
This patch ensures that we strip "\r" characters on both Windows as well
as Unix when we read text files. This should prevent the issue where
some Tor state files have been moved from a Windows machine, and thus
contains CRLF line ending, to a Unix machine where only \n is needed.
We add a test-case to ensure that we handle this properly on all our
platforms.

Pass the IPv4 before the IPv6 like all our other interfaces.

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.
Closes#40043.

Unclear but that somehow failed on Windows once (?) according to ticket #33768
but we are not seeing that failure.
Nevertheless, add a simple unit test.

This commit modifies the behavior of `parse_extended_address` in such a way
that if it fails, it will always return a `BAD_HOSTNAME` value, which is then
used to return the 0xF6 extended error code. This way, in any case that is
not a valid v2 address, we return the 0xF6 error code, which is the expected
behavior.

This reverts commit bf2a399fc0.
Don't set by default the prefer IPv6 feature on client ports because it breaks
the torsocks use case. The SOCKS resolve command is lacking a mechanism to ask
for a specific address family (v4 or v6) thus prioritizing IPv6 when an IPv4
address is asked on the resolve SOCKS interface resulting in a failure.
Tor Browser explicitly set PreferIPv6 so this should not affect the majority
of our users.

If no Address statement are found in the configuration file, attempt to learn
our address by looking at the ORPort address if any. Specifying an address is
optional so if we can't find one, it is fine, we move on to the next discovery
mechanism.
Note that specifying a hostname on the ORPort is not yet supported at this
commit.

This patch lifts the `tor_tls_cert_matches_key()` tests out of the
OpenSSL specific TLS test suite and moves it into the generic TLS test
suite that is executed for both OpenSSL and NSS.
This patch is largely a code movement, but we had to rewrite parts of
the test to avoid using OpenSSL specific data-types (such as `X509 *`)
and replace it with the generic Tor abstraction type
(`tor_x509_cert_impl_t *`).
This patch is part of the fix for TROVE-2020-001.
See: https://bugs.torproject.org/33119
In practice, there will be at most one ipv4 address and ipv6 address
for now, but this code is designed to not care which address is
which until forced to do so.
This patch does not yet actually create extend_info_t objects with
multiple addresses.
Closes#34069.
The find_my_address() function now prioritize the local interface over the
local hostname when guessing the IP address.
See proposal 312, section 3.2.1, general case:
https://gitweb.torproject.org/torspec.git/tree/proposals/312-relay-auto-ipv6-addr.txt#n359
The entire unit tests had to be refactored to make this possible. Instead of
hot patching it, it has been rewritten to cover all possible cases and the
test interface has been changed to accomodate both IPv4 and IPv6 in order for
them to be tested identically.

These tests don't actually exercise the authority IPv6 ORPort
self-add feature in 32822, but they do improve coverage of the
related config code.
Part of 32822.
The exposed interface is "stats/" thus make the unit tests clear that it is
testing that specific GETINFO command.

New name reflects that the function is only used to compare router addresses
in order to learn if they are in the same network.
The network check is /16 and /32 respectively for IPv4 and IPv6.
