1f58b0ca26 router: Authorities add their own IPv6 to trusted dir servers
Authorities currently add themselves to the trusted dir servers list,
but if they have an IPv6 ORPort, they leave it out.

This commit makes authorities add their own IPv6 ORPort to the trusted
dir servers list.

Closes ticket 32822.

5d956d797b Add a comment explaining reachability vs bandwidth self-tests
This is in response to a question about why we don't always log
orport self-tests as reachability tests.

I'm not 100% convinced that bandwidth self-tests are still useful,
but that's an issue for another day. :)

2238b6320b Refactor reachability test logging: log exactly what we launch.
Previously we had two chains of logic for reachability tests: one
for launching them, and one for telling the user that we had
launched them.  Now, we simply have the launch code inform the user:
this way, we can't get out of sync.

Closes ticket 34137.

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

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.

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.

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.

c116728209 Use __attribute__((fallthrough)) rather than magic GCC comments.
GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that.  Clang recently added
the same thing.

GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments.  Clang, however,
only seems to like "__attribute__((fallthrough))".  Fortunately, GCC
accepts that too.

A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.

This is an automated commit, made with the following perl one-liner:

  #!/usr/bin/perl -i -p
  s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

(In order to avoid conflicts, I'm applying this script separately to
each maint branch. This is the 0.4.3 version.)
