When marking for close a circuit, the reason value, a integer, was assigned to
a uint16_t converting any negative reasons (internal) to the wrong value. On
the HS side, this was causing the client to flag introduction points to be
unreachable as the internal reason was wrongfully converted to a positive
16bit value leading to flag 2 out of 3 intro points to be unreachable.
Fixes#20307 and partially fixes#21056

- Also remove LCOV marks from blocks of code that can be reachable by tests
if we mock relay_send_command_from_edge().

With the previous commit, we validate the circuit _before_ calling
rend_mid_introduce() which handles the INTRODUCE1 payload.

Adds a better semantic and it also follows the same interface for the
INTRODUCE1 API which is circuit_is_suitable_for_introduce1().

That way, when we are parsing the options and LearnCircuitBuildTimeout is set
to 0, we don't assert trying to get the options list with get_options().

This patch refactors duplicated code, to check if a given router
supports fetching the extra-info document, into a common macro called
SKIP_MISSING_TRUSTED_EXTRAINFO.
This patch generalizes the two functions
router_is_already_dir_fetching_rs and router_is_already_dir_fetching_ds
into a single function, router_is_already_dir_fetching_, by lifting the
passing of the IPv4 & IPv6 addresses and the directory port number to
the caller.
So far, the TTLs for both A and AAAA records were not initialised,
resulting in exit relays sending back the value 60 to Tor clients. This
also impacts exit relays' DNS cache -- the expiry time for all domains
is set to 60.
This fixes <https://bugs.torproject.org/19025>.
