i don't know if whitespace is ok to have before preprocessing
directives on all platforms, but anyway we almost never have it,
so now things are more uniform.
Before this commit, the control events were never triggered. It was introduced
with commit 0c19ce7bde.
Fixes#26082

There are three cases where this can happen: changes in our
controller events, changes in our DisableNetwork setting, and
changes in our hibernation state.
Closes ticket 26063.
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.
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.
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.

* ADD new /src/common/crypto_rand.[ch] module.
* ADD new /src/common/crypto_util.[ch] module (contains the memwipe()
function, since all crypto_* modules need this).
* FIXES part of #24658: https://bugs.torproject.org/24658
Add a missing lock acquisition around access to queued_control_events
in control_free_all(). Use the reassign-and-unlock strategy as in
queued_events_flush_all(). Fixes bug 25675. Coverity found this bug,
but only after we recently added an access to
flush_queued_event_pending.
There was a nonfatal assertion in pathbias_should_count that would
trigger if onehop_tunnel was set, but the desired_path_length was
greater than 1. This patch fixes that. Fixes bug 24903; bugfix on
0.2.5.2-alpha.
This patch is a result of auditing all of our uses of
get_datadir_fname() and its kin, and dividing them into cache vs
keys vs other data.
The new get_keydir_fname() and get_cachedir_fname() functions don't
actually do anything new yet.
This is removed for two reasons. First, HSDir accepts descriptor even though
they don't think they are in fact an HSDir. This is to avoid consensus desync
between client/service and directories.
Second, our malicious HSDir scanner uses the HSPOST command to post on all
relays in order to test them before they could become HSDir. We had to remove
that check from the tor code that the scanner uses.
Thus, this check should not be enforced by the control port for the above use
cases. It is also a bit more complex with v3 support for which not all HSDir
support it so basically irrelevant check.

This makes the REPLICA= field optional for the control port event. A v2
service will always pass it and v3 is ignored.

A new v3 specific function has been added named
control_event_hsv3_descriptor_failed().
The HS v3 subsystem now uses it.

This changes the control_event_hs_descriptor_requested() call to add the hsdir
index optional value. v2 passes NULL all the time.
This commit creates hs_control.{c|h} that contains wrappers for the HS
subsystem to interact with the control port subsystem.
The descriptor REQUESTED event is implemented following proposal 284 extension
for v3.
