4a2347d290 Merge branch 'maint-0.4.3'

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.)

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

37aae23945 OOM-purge the DNS cache one part at a time
Previously we purged it in 1-hour increments -- but one-hour is the
maximum TTL for the cache!  Now we do it in 25%-TTL increments.

Fixes bug 29617; bugfix on 0.3.5.1-alpha.

3c2648bbda Move "relay" and "router" periodic callbacks out of mainloop.c
(Some of these callbacks are specific to the OR module, so now it's
time to have an or_sys and or_periodic.)

0034f10956 Use safe_mem_is_zero in a few more places.
I don't believe any of these represent a real timing vulnerability
(remote timing against memcmp() on a modern CPU is not easy), but
these are the ones where I believe we should be more careful.

Also remove all checks for the return value, which were redundant anyway,
