This function must return false if the module is not compiled in. In order to
do that, we move the authdir_mode_v3() function out of router.c and into the
dirauth module new header file named mode.h.
It is always returning false if we don't have the module.

This patch adds a new node_has_preferred_descriptor() function, and
replaces most users of node_has_descriptor() with it. That's an
important change, since as of d1874b4339 (our fix for #25213),
we are willing to say that a node has _some_ descriptor, but not the
_right_ descriptor for a particular use case.
Part of a fix for 25691 and 25692.
Coverity found a null pointer reference in nodelist_add_microdesc().
This is almost certainly impossible assuming that the routerstatus_t
returned by router_get_consensus_status_by_descriptor_digest() always
corresponds to an entry in the nodelist. Fixes bug 25629.
Previously, we wouldn't do this when running with a routerinfo_t in
some cases, leading to many needless calls to the protover module.
This change also cleans up the code in nodelist.c a bit.
Fixes bug 25008; bugfix on 0.2.9.4-alpha.
The node_get_ed25519_id() warning can actually be triggered by a relay flagged
with NoEdConsensus so instead of triggering a warning on all relays of the
network, downgrade it to protocol warning.

When the directory information changes, callback to the HS client subsystem so
it can check if any pending SOCKS connections are waiting for a descriptor. If
yes, attempt a refetch for those.

Before, this function meant "can we connect to this node and
authenticate it using its ed25519 key?" Now it can additionally
mean, "when somebody else connects to this node, do we expect that
they can authenticate using the node's ed25519 key"?
This change lets us future-proof our link authentication a bit.
Closes ticket 20895. No backport needed, since ed25519 link
authentication support has not been in any LTS release yet, and
existing releases with it should be obsolete before any releases
without support for linkauth=3 are released.
This is a large and important unit test for the hidden service version
3! It tests the service reachability for a client using different
consensus timings and makes sure that the computed hashring is the same
on both side so it is actually reachable.

With the latest change on how we use the HSDir index, the client and service
need to pick their responsible HSDir differently that is depending on if they
are before or after a new time period.
The overlap mode is active function has been renamed for this and test added.
