The last hop in vanguard circuits can be an RP/IP/HSDir.
Since vanguard circuits are at least 3 hops (sometimes 4) before this node,
this change will not cause A - B - A paths.
When parsing a vote in routerparse.c, only dirauth extract the commits from
the vote so move all this code into dirvote.c so we can make it specific to
the dirauth module.
If the dirauth module is disabled, the commit parsing does nothing.

From dirvote.c to networkstatus.c where it makes more sense both in terms of
namespace and subsystem responsability.
This removes one less dependency on the dirauth module.

Add static inline dirauth public functions used outside of the dirauth module
so they can be seen by the tor code but simply do nothing.

Move most of the shared random functions that are needed outside of the
dirauth module.
At this commit, because dirvote.c hasn't been refactor, it doesn't compile
because some SR functions need a dirvote function.
Furthermore, 5 functions haven't been touched yet because they are dirauth
only but are in used in other C files than the dirauth module ones.
No code behavior change. Only moving code around.

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.

Because we rescan the main loop event list if the global map of services has
changed, this makes sure it does work.
Signed-off-by: David Goulet <dgoulet@torproject.org>
Because ADD_ONION/DEL_ONION can modify the global service map (both for v2 and
v3), we need to rescan the event list so we either enable or disable the HS
service main loop event.

This is done because it makes our life easier with unit tests. Also, a rescan
on an uninitialized event list will result in a stacktrace.

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.

Prior to #23100, we were not counting HS circuit build times in our
calculation of the timeout. This could lead to a condition where our timeout
was set too low, based on non HS circuit build times, and then we would
abandon all HS circuits, storing no valid timeouts in the histogram.
This commit avoids the assert.
When Travis CI runs make distcheck, test-suite.log doesn't exist in
the expected place. Add a new make target to show this file and use
it when DISTCHECK=yes in .travis.yml. Fixes bug 25814; bug not in any
released Tor.
Needed to run tests from the tarball else the geoip unit test would fail by
not finding that file.

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.
Our main function, though accurate on all platforms, can be very
slow on 32-bit hosts. This one is faster on all 32-bit hosts, and
accurate everywhere except apple, where it will typically be off by
1%. But since 32-bit apple is a relic anyway, I think we should be
fine.
Previously were using this value to have a cheap highish-resolution
timer. But we were only using it in one place, and current dogma is
to use monotime_coarse_t for this kind of thing.
