We still do this time update here, since we do it from all
callbacks, but it is no longer a reason to keep the once-per-second
callback enabled.
Closes ticket 26009.
Since we're going to be disabling the second-elapsed callback, we're
going to sometimes have long periods when no events file, and so the
current second is not updated. Handle that by having a better means
to detect "clock jumps" as opposed to "being idle for a while".
Tolerate far more of the latter.
Part of #26009.
This functions is now used outside of networkstatus.c and makes more sense to
be in config.c.
It is also renamed to options_any_client_port_set() for the config.c
namespace.
No code behavior change.

Now it has a function that can tell the rest of Tor whether any
once-a-second controller item should fire, and a function to fire
all the once-a-second events.
We cleared this value in second_elapsed_callback. But what were we
using it for? For detecting if Libevent returned EINVAL too often!
We already have a way to detect too-frequent events, and that's with
a ratelim_t. Refactor the code to use that instead. Closes ticket
26016.
This function must return false if the module is not compiled in. In order to
do that, we move the authdir_mode_v3() function out of router.c and into the
dirauth module new header file named mode.h.
It is always returning false if we don't have the module.

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.
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.
This is a pretty big commit but it only moves these files to src/or/dirauth:
dircollate.c dirvote.c shared_random.c shared_random_state.c
dircollate.h dirvote.h shared_random.h shared_random_state.h
Then many files are modified to change the include line for those header files
that have moved into a new directory.
Without using --disable-module-dirauth, everything builds fine. When using the
flag to disable the module, tor doesn't build due to linking errors. This will
be addressed in the next commit(s).
No code behavior change.
