b396e4e429 Move unreachable port warnings to a periodic event.
Arguably, the conditions under which these events happen should be a
bit different, but the rules are complex enough here that I've tried
to have this commit be pure refactoring.

Closes ticket 25952.

Finally, before this code goes away, take a moment to look at the
amazing way that we used to try to have an event happen
every N seconds:

      get_uptime() / N != (get_uptime()+seconds_elapsed) / N

Truly, it is a thing of wonder.  I'm glad we didn't start using this
pattern everywhere else.

2d79d0155e vote: Move dirvote_recalculate_timing() to voting_schedule.c
By doing so, it is renamed to voting_schedule_recalculate_timing(). This
required a lot of changes to include voting_schedule.h everywhere that this
function was used.

This effectively now makes voting_schedule.{c|h} not include dirauth/dirvote.h
for that symbol and thus no dependency on the dirauth module anymore.

bbf0b92b1c Fix an assertion failure introduced by #25948
Apparently, we can decide our state is dirty before we create the
event to tell the mainloop that we should save it.  That's not a
problem, except for the assertion failure.

0d8604c763 Give queued_events_flush_all() responsibility for flushing log cbs
This requires that when a log cb happens, the event for flushing
queued events is scheduled, so we also add the necessary machinery
to have that happen.

Note that this doesn't actually help with logs from outside the main
thread, but those were already suppressed: see #25987 for a ticket
tracking that issue.

b0224bf728 Add a mechanism for the logging system to report queued callbacks
Sometimes the logging system will queue a log message for later.
When it does this, the callback will either get flushed at the next
safe time, or from the second-elapsed callback.

But we're trying to eliminate the second-elapsed callback, so let's
make a way for the log system to tell its users about this.

d8509b450a vote: Return error when adding vote/signature if no dirauth module
Commit 0f3b765b3c added
tor_assert_nonfatal_unreached() to dirvote_add_vote() and
dirvote_add_signatures() when the dirauth module is disabled.

However, they need to return a value. Furthermore, the dirvote_add_vote()
needs to set the msg_out and status_out so it can be sent back. Else,
uninitialized values would be used.

15e8ce3937 Move back dirvote_authority_cert_dup to dirvote.c

longer needed. In doing so, we put it back in dirvote.c and reverted its name
to the original one:

dirvote_authority_cert_dup() --> authority_cert_dup()

0f3b765b3c dirvote: Handling adding vote and signature if module is disabled
Both functions are used for directory request but they can only be used if the
running tor instance is a directory authority.

For this reason, make those symbols visible but hard assert() if they are
called when the module is disabled. This would mean we failed to safeguard the
entry point into the module.
