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.

Remove useless include.
Clearly identify functions that are used by other part of Tor, functions that
are only used by the dirauth subsystem and functions that are exposed for unit
tests.
This will help us in the dirauth modularization effort.

Many functions become static to the C file or exposed to the tests within the
PRIVATE define of dirvote.h.
This commit moves a function to the top. No code behavior change.

Don't access the AuthoritativeDir options directly. We do this so we can move
authdir_mode() to the dirauth module.

Make our build system support a disable dirauth module option. It can only be
disabled explicitly with:
$ ./configure --disable-module-dirauth
If *not* specified that is enabled, an automake conditional variable is set to
true and a defined value for the C code:
AM_CONDITIONAL: BUILD_MODULE_DIRAUTH
AC_DEFINE: HAVE_MODULE_DIRAUTH=1
This introduces the dirauth/ module directory in src/or/ for which .c files
are only compiled if the BUILD_MODULE_DIRAUTH is set.
All the header files are compiled in regardless of the support so we can use
the alternative entry point functions of the dirauth subsystem.

When we change the hibernation state, rescan the main loop event list because
the new state might affect the events.

Implement the ability to set flags per events which influences the set up of
the event.
This commit only adds one flag which is "need network" meaning that the event
is not enabled if tor has disabled the network or if hibernation mode.

In 25374, we created the necessary post-loop event for scheduling
connection_ap_attach_pending as needed. Before that, we were
already running this event once per mainloop. There's no reason to
also run it once per second.
Closes ticket 25933. No changes file, since the relevant change is
already in 25374. Or possibly in 17590, depending on how you look
at it.
Previously, we were ignoring values _over_ EPSILON. This bug was
also causing a warning at startup because the default value is set
to -1.0.
Fixes bug 25577; bugfix on 6b1dba214d. Bug not in any released tor.
Two helper functions to enable an event and disable an event which wraps the
launch and destroy of an event but takes care of the enabled flag.
They are also idempotent that is can be called multiple time on the same event
without effect if the event was already enabled or disabled.

In case we transitionned to a new role in Tor, we need to launch and/or
destroy some periodic events.
Signed-off-by: David Goulet <dgoulet@torproject.org>
In tor, we have a series of possible "roles" that the tor daemon can be
enabled for. They are:
Client, Bridge, Relay, Authority (directory or bridge) and Onion service.
They can be combined sometimes. For instance, a Directory Authority is also a
Relay. This adds a "roles" field to a periodic event item object which is used
to know for which roles the event is for.
The next step is to enable the event only if the roles apply. No behavior
change at this commit.

No behavior change, just to make it easier to find callbacks and for the sake
of our human brain to parse the list properly.
