f81e4aa831 hs-v2: Lookup intro failure cache when picking an intro from descriptor
When picking an intro point from the service descriptor, the client failed to
lookup the failure cache.

It made an HS v2 client re-pick bad intro points for which we already know it
won't work in the first place.

Based on Neel Chauhan original patch.

dc6d7f072d Make foo_validate() functions call config_validate().
The former foo_validate() functions are now toplevel
legacy_validate_fn callbacks.  The new foo_validate() functions now
call them.

This change lets us remove the old shared_random disk state
validation callback entirely.

4a248bafba Rename validate_fn{,_t} to start with "legacy_".
The current API of this callback mixes responsibilities, including:
  * validation
  * transition checking
  * processing (modifying) the configuration object.

These will have to be disentangled piece by piece, so for now, we'll
have "legacy" validate functions as well.

3867ca4925 dir: Return 503 code when rejecting single hop request
Single hop rejection (POST and GET) for HS v3 descriptor now return a 503 code
which is more accurate code from dir-spec.txt and from other rejection case in
the code.

For instance if you are not a relay and you get a POST request, a 503 code is
sent back with a rejection message.

09468cc58b dir: Look if circuit is closed in connection_dir_is_anonymous()
Before inspecting the p_chan, we must check if the circuit is marked for close
because if it is the case, the channels are nullified from the circuit.

Several valid cases can mark the circuit for close of the directory
connection.

ed57a04a65 hs-v3: Remove a BUG() caused by an acceptable race
hs_client_purge_state() and hs_cache_clean_as_client() can remove a descriptor
from the client cache with a NEWNYM or simply when the descriptor expires.

Which means that for an INTRO circuit being established during that time, once
it opens, we lookup the descriptor to get the IP object but hey surprised, no
more descriptor.

The approach here is minimalist that is accept the race and close the circuit
since we can not continue. Before that, the circuit would stay opened and the
client wait the SockTimeout.

Fixers #28970.

b6c24eb484 hs-v3: Remove the circuit_established intro flag
Only use the HS circuit map to know if an introduction circuit is established
or not. No need for a flag to keep state of something we already have in the
circuit map. Furthermore, the circuit map gets cleaned up properly so it will
always have the "latest truth".

This commit also removes a unit test that was testing specifically that flag
but now we rely solely on the HS circuit map which is also tested few lines
below the removed test.
