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.

743d0b9d91 hs-v3: Implement HS_DESC REQUESTED event
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.

e7d606900e control: Rename two HS v2 specific functions
Make control_event_hs_descriptor_received() and
control_event_hs_descriptor_failed() v2 specific because they take a
rend_data_t object and v3 will need to pass a different object.

No behavior change.

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.

This is a naming refactor mostly _except_ for a the events' function that take
a rend_data_t which will require much more refactoring.

No behavior change at this commit, cleanup and renaming stuff to not be only
v2 specific.

4633a93ca8 hs-v3: Downgrade warning log when an intro circuit has closed
When an intro circuit has closed, do not warn anymore when we can't find the
service. It is possible to hit that condition if the service is removed before
the circuits were fully closed. This happens in the case of deleting an

49f21b6ba3 control: Support HSv3 interface for ADD_ONION
At this commit, the key handling and generation is supported for a v3 service
(ED25519-V3). However, the service creation is not yet implemented. This only
adds the interface and code to deal with the new ED25519-V3 key type.

Tests have been updated for RSA key type but nothing yet for ED25519-v3.

981bb60575 circuit: Don't timeout opened C_INTRODUCING circuit
A circuit with purpose C_INTRODUCING means that its state is opened but the
INTRODUCE1 cell hasn't been sent yet. We shouldn't consider that circuit when
looking for timing out "building circuit". We have to wait on the rendezvous
circuit to be opened before sending that cell so the intro circuit needs to be
kept alive for at least that period of time.

This patch makes that the purpose C_INTRODUCING is ignored in the
circuit_expire_building() which means that we let the circuit idle timeout
take care of it if we end up never using it.

Fixes #23681
