The comment of that specific unit test wanted 4 ORPorts but for some reasons
we tested for 3 which before the previous commit related to #40289, test would
pass but it was in fact wrong.
Now the code is correct and 4 was in fact correct expected number of ports.

We were just looking at the family which is not correct because it is possible
to have two explicit ORPort for the same family but different addresses. One
example is:
ORPort 127.0.0.1:9001 NoAdvertise
ORPort 1.2.3.4:9001 NoListen
Thus, this patch now ignores ports that have different addresses iff they are
both explicits. That is, if we have this example, also two different
addresses:
ORPort 9001
ORPort 127.0.0.1:9001 NoAdvertise
The first one is implicit and second one is explicit and thus we have to
consider them for removal which in this case would remove the "ORPort 9001" in
favor of the second port.
Fixes #40289

Fun bug where we thought we were using the default "false" value when an
implicit address was detected but if we had an explicit address before, the
flag was set to true and then we would only use that value.
And thus, for some configurations, implicit addresses would be flagged as
explicit and then configuring ports goes bad.

In other words, if PublishServerDescriptor is set to 0 and AssumeReachable to
1, then allow a relay to hold a RFC1918 address.
Reasons for this are documented in #40208

That comes from 685c4866acf8489c58aca41ec01aa5a53e39220a which added that
check correctly except for when we build a descriptor.
We already omit the IPv6 address, if we need to, when we encode the descriptor
but we need to keep the actual discovered address in the descriptor so we can
notice future IP changes and be able to assess that we are not publishable as
long as we don't specifically set the omit flag.
This lead to also having tor noticing that our IP changed from <nothing> (no
IPv6 in the descriptor) to a discovered one which would trigger every minute.

Handle the EOF situation for a metrics connection. Furthermore, if we failed
to fetch the data from the inbuf properly, mark the socket as closed because
the caller, connection_process_inbuf(), assumes that we did so on error.

Previously we would warn in this case... but there's really no
justification for doing so, and it can only cause confusion.
Fixes bug #40281; bugfix on 0.4.0.1-alpha.

In two instances we must look at this flag:
1. When we build the descriptor so the IPv6 is NOT added to the descriptor in
case we judge that we need to omit the address but still publish.
2. When we are deciding if the descriptor is publishable. This flags tells us
that the IPv6 was not found reachable but we should still publish.

This was a bad copy and paste error from the previous commit which
generated a duplicated entry error from practracker.

We solve this error by allowing the connection_exit_connect() function
to be 130 lines long.

While trying to resolve our CI issues, the Windows build broke with an
unused function error:
src/test/test_switch_id.c:37:1: error: ‘unprivileged_port_range_start’
defined but not used [-Werror=unused-function]
We solve this by moving the `#if !defined(_WIN32)` test above the
`unprivileged_port_range_start()` function defintion such that it is
included in its body.
This is an unreviewed commit.

We currently assume that the only way for Tor to listen on ports in the
privileged port range (1 to 1023), on Linux, is if we are granted the
NET_BIND_SERVICE capability. Today on Linux, it's possible to specify
the beginning of the unprivileged port range using a sysctl
configuration option. Docker (and thus the CI service Tor uses) recently
changed this sysctl value to 0, which causes our tests to fail as they
assume that we should NOT be able to bind to a privileged port *without*
the NET_BIND_SERVICE capability.
In this patch, we read the value of the sysctl value via the /proc/sys/
filesystem iff it's present, otherwise we assume the default
unprivileged port range begins at port 1024.
