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.
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.

Originally, it was made public outside of the dirauth module but it is no
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()

The --disable-module-* configure option removes code from the final binary but
we still build the unit tests with the disable module(s) so we can actually
test that code path all the time and not forget about it.

This code is only for dirauth so this commit moves it into the module in
dirvote.c.
No code behavior change.

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.

In order to further isolate the dirauth code into its module, this moves the
handling of the directory request GET /tor/status-vote/* into the module.

In order to make sr_commit_free() only used by the dirauth module, this
commits moves the commits free from a vote object into the dirvote.c file
which is now only for the module.
The function does nothing if the module is disabled.

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.
