cb25f57724 Remove stub macro for router_new_consensus_params()
I had incorrectly believed that the router.c file was disabled when
we were building with relay mode disabled.

edb023b1e7 Add an AssumeReachableIPv6 autobool option.
This option tells Tor that our IPv6 orport is reachable, and doesn't
need to be checked.

Closes the rest of 33224.

6edf7f6710 Add two new networkstatus parameters to emulate AssumeReachable.
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.

5c5fb0fcca Move code into notify_after_networkstatus_changes().
The purpose of having this function was to inform other code that
the consensus has changed, so it should go there.

b76325190b addr: Remove resolve_my_address_v4()
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.

2f3b4e3888 addr: Refactor is_local_addr() to support IPv6
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.

7795dd7ef6 addr: Refactor last resolved address cache accessors
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.

b365179ee0 reachability_warnings_callback: simplify v4/v6_ok logic
Since "skip orport check" is the "and" of v4_ok and v6_ok, we can
just compute v4_ok and v6_ok once, to clarify that we don't enter
this block of code if they're both true.

47f9edde69 config: Change Address to be a LINELIST
With prop312, we want to support IPv4 and IPv6 thus multiple Address statement
(up to 2) will be accepted.

For this, "Address" option becomes a LINELIST so we can properly process the
IPv4 or/and IPv6.

bc9979a670 Split "can reach ipv4 orport" from "can reach ipv6 orport".
I've managed to keep this change mainly contained to our
self-testing module.  The changes here are:

  * There are two different variables for tracking "is our orport
    reachable".

  * We have a new function that says whether we can skip a single
    family's orport reachability test; the old function for this now
    tells whether we can skip _all_ orport reachability testing.

    (The name, router_should_skip_orport_reachability_test, is not
    so good.  I will rename it later if I can think of a good
    replacement.)

  * The function that launches orport reachability tests now only
    launches the ones that haven't completed.

  * The function that notes that we're reachable on an ORPort now
    takes a family.

  * Various log messages are cleaned up.
