If our TLS connection fails for a "misc" reason, we don't need to
say that the reason is "misc" -- we can at least localize it to
the TLS module.
Part of a fix for #32622.
Previously, we would only update this field when the error happened
during a read.
This will improves our reporting for our bootstrap status, and help
to address #32622. The problem is not completely solved by this
patch, however: too many errors are still lumped into "MISC".
AssumeReachable should only be about whether a relay thinks that it
is reachable itself. But previously, we've had it also turn off
reachability checking of _other_ relays on authorities.
(Technically, reachability tests were still run, but we would ignore
the results.)
With this patch, there is a new AuthDirTestReachability option
(default 1) that controls whether authorities run reachability
tests.
Making this change allows us to have test networks where authorities
set AssumeReachable without disabling their reachability testing
entirely.
Closes ticket #34445.
These parameters do not suppress checks, but they tell relays that
it's okay to publish even when those checks fail.
I have chosen lowercase hyphenated names, since these seem to be
more common in networkstatus params.
Closes#33224 and part of #34064.
This was supposed to happen in #40012, but the command line was wrong.

Instead of a complex if/else block, use a table of functions that have the
same interface and each of them attempt to find the address one after the
other.

By doing this, a memory leak was found with "hostname_used" that could have
been overwritten by another function.
This commit changes that by making it a NULL string instead.

The last resolved address cache uses an index that is mapped to an address
family (AF_INET and AF_INET6).
This commit adds a conversion function from af to index and change the code to
use that all the time only.
In the process, this commit fixes a bug that the last resolved address
accessors were using the af value insted of the index.

Replace it by find_my_address() everywhere. This changes many parts of the
code that uses it to use a tor_addr_t instead of a plain uint32_t for IPv4.
Many changes to the unit test to also use the new interface.

Series of changes:
1. Rename function to reflect the namespace of the file.
2. Use the new last resolved cache instead of the unused
last_resolved_addr_v4 (which is also removed in this commit).
3. Make the entire code base use the new resolved_addr_is_local() function.
You will notice that this function uses /24 to differentiate subnets where the
rest of tor uses /16 (including documentation of EnforceDistinctSubnets).
Ticket #40009 has been opened for that.
But that the moment, the function keeps looking at /24.

Series of things done in this commit:
1. Rename the functions to better reflect the namespace of the file.
2. Make both reset and get function to operate on the last_resolved_addrs
cache that is per family.
3. Make the get function to take a tor_addr_t.
4. Change all callsite to use the new convention.

In order to transition smoothly, maek resolve_my_address_v4() call the new
fancy find_my_address() with AF_INET.
Next commits should remove the use of resolve_my_address_v4() accross the code
to use find_my_address().
This commit is so the unit tests would be more easily fixed and port to the
new find_my_address() internals.
Part of #33233.

resolve_my_address() was beyond repair in terms of refactoring. Way too
complex and doing too many things.
This commit implements find_my_address() which in theory does the same as
resolve_my_address() but in a more clean, concise and modern way using the
tor_addr_t interface and for multiple address family.
The caller needs to pass the address family (IPv4 or IPv6) which this
interface supports. For both, a last resolved cache is used as well.

These identifiers are confusing and unreadable. I think these
replacements should be better. Closes ticket #40012.
