f954514b37 Merge branch 'maint-0.4.1' into maint-0.4.2
This is an "ours" merge to avoid taking the 0.4.1 version of the 34078 fix.

79ff2b6aab 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 0.4.1 version.)

2cd1c07658 hs_dos.c: rewrite a comment not to say "fallthrough"
There's nothing wrong with the comment, but the script I'm about to
apply wouldn't like it.

6c3c94357c Add a fallthrough macro.
This macro defers to __attribute__((fallthrough)) on GCC (and
clang).  Previously we had been using GCC's magic /* fallthrough */
comments, but clang very sensibly doesn't accept those.

Since not all compiler recognize it, we only define it when our
configure script detects that it works.

Part of a fix for 34078.

445df9e7b5 relay: New file relay_resolve_addr.{c|h}
This commit moves router_pick_published_address() and the related helper
functions into the new file.

The log_addr_has_changed() function has been made public in router.h so we can
use it in relay_resolve_addr.c.

This is a refactoring as part of Sponsor 55. Only code movement at this
commit.

b1c383e3e6 Fix a GCC 10.0.1 compilation error.
Do not try to stuff "HS_DESC_DECODE_GENERIC_ERROR" (-1) into a
socks5_reply_status_t (enum).  It doesn't actually make sense, and
isn't one of our documented extensions.

(This can only happen on a nonfatal assertion that we haven't seen,
so it probably isn't happening in practice.)

Fixes another case of bug 34077; bugfix on 0.4.3.1-alpha.

4a36dfebee circuitbuild: Allow relays to send IPv6 extend cells
Allow relays and bridges to send IPv4 or IPv6 extend cells.
But keep restricting clients to IPv4 extend cells, because sending IPv6
extend cells would be an obvious version distinguisher.

When a relay starts testing reachability, log its IPv6 ORPort.
The existing code logs the IPv4 ORPort and DirPort.

The IPv4 ORPort is required. The other ports are only logged if they
are present.
