ded99992b8 Bail out of format_networkstatus_vote if fmt_addr32() failed.
Something is fishy if we cannot put IP address string into dir-vote line.

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.)

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.
