475d8d1a3d control: Don't check if Server is an HSDir for HSPOST
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.

e71c6199dd hs-v3: Add a public function to upload a descriptor to an HSDir
This is groundwork for the HSPOST control port command that needs a way in the
HS subsystem to upload a service descriptor to a specific HSDir.

To do so, we add a public function that takes a series of parameters including
a fully encoded descriptor and initiate a directory request to a specific
routerstatut_t object.

It is for now not used but should be, in future commit, by the HSPOST command.
This commit has no behavior change, only refactoring.

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

beacbbe210 control: Refactor control_event_hs_descriptor_receive_end
First, rename and make that function static because it is internal to
control.c and called by two HS_DESC events.

Second, make it take more basic parameters and thus not a rend_data_t object
so we can still use the function for v3 HS that doesn't use that object.

Third, move the descriptor ID lookup to the two specific events (yes little
code duplication there) because they get a rend_data_t object which won't be
the case for v3.

Finally, through this refactoring, change the pointer check to BUG() and
change some parameter names to reflect what they really are.

No behavior change at this commit.

e80893e51b hs-v3: Cleanup HS circuits when marking as closed
First, hs_service_intro_circ_has_closed() is now called in circuit_mark_for
close() because the HS subsystem needs to learn when an intro point is
actually not established anymore as soon as possible. There is a time window
between a close and a free.

Second, when we mark for close, we also remove it from the circuitmap because
between the close and the free, a service can launch an new circuit to that
same intro point and thus register it which only succeeds if the intro point
authentication key is not already in the map.

However, we still do a remove from the circuitmap in circuit_free() in order
to also cleanup the circuit if it wasn't marked for close prior to the free.

ba63c4099a hs-v3: Don't cleanup intro point in has_closed()
The hs_service_intro_circ_has_closed() was removing intro point objects if too
many retries.

We shouldn't cleanup those objects in that function at all but rather let
cleanup_intro_points() do its job and clean it properly.

This was causing an issue in #23603.

Furthermore, this moves the logic of remembering failing intro points in the
cleanup_intro_points() function which should really be the only function to
know when to cleanup and thus when an introduction point should be remembered
as a failed one.

97702c69b0 sched: Set channel scheduler state to IDLE when not opened
In the KIST main loop, if the channel happens to be not opened, set its state
to IDLE so we can release it properly later on. Prior to this fix, the channel
was in PENDING state, removed from the channel pending list and then kept in
that state because it is not opened.

This bug was introduced in commit dcabf801e5 for
which we made the scheduler loop not consider unopened channel.

This has no consequences on tor except for an annoying but harmless BUG()
warning.
