dirvote_get_next_valid_after_time() is the only public function that uses the
voting schedule outside of the dirvote subsystem so if it is zeroed,
recalculate its timing if we can that is if a consensus exists.

Because the HS and SR subsystems can use the voting schedule early (with the
changes in #23623 making the SR subsystem using the static voting schedule
object), we need to recalculate the schedule very early when setting the new
consensus.

If it decrypts something that turns out to start with a NUL byte,
then decrypt_desc_layer() will return 0 to indicate the length of
its result. But 0 also indicates an error, which causes the result
not to be freed by decrypt_desc_layer()'s callers.
Since we're trying to stabilize 0.3.2.x, I've opted for the simpler
possible fix here and made it so that an empty decrypted string will
also count as an error.
Fixes bug 24150 and OSS-Fuzz issue 3994.
The original bug was present but unreachable in 0.3.1.1-alpha. I'm
calling this a bugfix on 0.3.2.1-alpha since that's the first version
where you could actually try to decrypt these descriptors.
Few issues...
* Malformed ReducedExitPolicy, causing brackets to appear.
* ExitPolicyDefault wasn't actually listed, instead it munged the description
into the ExitPolicy description.
* Extra plus signs in the ExitPolicy and ReducedExitPolicy entries. After an
hour of struggling with asciidoc couldn't figure out how to format it as
'paragraph => example => paragraph with same indentation' so just
rearranging the ExitPolicy entry.
Patches welcome if someone strongly prefers having the paragraph after the
example.

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 a BUG() occurs, this macro will print extra information about the state
of the scheduler and the given channel if any. This will help us greatly to
fix future bugs in the scheduler especially when they occur rarely.

When running "make test-network-all", test that IPv6-only clients can use
microdescriptors. IPv6-only microdescriptor client support was fixed in
tor 0.3.0.1-alpha.
Requires chutney master 61c28b9 or later.
Closes ticket 24109.
They are not yet implemented: they will upload descriptors, but won't be
able to rendezvous, because IPv6 addresses in link specifiers are ignored.
Part of #23820.
The previous version of this function had the following issues:
* it didn't check if the extend_info contained an IPv6 address,
* it didn't check if the ed25519 identity key was valid.
But we can't add IPv6 support in a bugfix release.
Instead, BUG() if the address is an IPv6 address, so we always put IPv4
addresses in link specifiers. And ignore missing ed25519 identifiers,
rather than generating an all-zero link specifier.
This supports v3 hidden services on IPv4, dual-stack, and IPv6, and
v3 single onion services on IPv4 only.
Part of 23820, bugfix on 0.3.2.1-alpha.
