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.
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.

Because the HS subsystem needs the voting schedule to compute time period, we
need all tor type to do that.

The new decryption function performs no decryption, skips the salt,
and doesn't check the mac. This allows us to fuzz the
hs_descriptor.c code using unencrypted descriptor test, and exercise
more of the code.
Related to 21509.
The exposed get_voting_schedule() allocates and return a new object everytime
it is called leading to an awful lot of memory allocation when getting the
start time of the current round which is done for each node in the consensus.

If the intro point supports ed25519 link authentication, make sure we don't
have a zeroed key which would lead to a failure to extend to it.
We already check for an empty key if the intro point does not support it so
this makes the check on the key more consistent and symmetric.

The previous version of these functions had the following issues:
* they can't supply both the IPv4 and IPv6 addresses in link specifiers,
* they try to fall back to a 3-hop path when the address for a direct
connection is unreachable, but this isn't supported by
launch_rendezvous_point_circuit(), so it fails.
But we can't fix these things in a bugfix release.
Instead, always put IPv4 addresses in link specifiers.
And if a v3 single onion service can't reach any intro points, fail.
This supports v3 hidden services on IPv4, dual-stack, and IPv6, and
v3 single onion services on IPv4 only.

The previous version of this function has the following issues:
* it doesn't choose between IPv4 and IPv6 addresses correctly, and
* it doesn't fall back to a 3-hop path when the address for a direct
connection is unreachable.
But we can't fix these things in a bugfix release.
Instead, treat IPv6 addresses like any other unrecognised link specifier
and ignore them. If there is no IPv4 address, return NULL.
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.
Turns out that when reloading a tor configured with hidden service(s), we
weren't copying all the needed information between the old service object to
the new one.
For instance, the desc_is_dirty timestamp wasn't which could lead to the
service uploading its desriptor much later than it would need to.
The replaycache wasn't also moved over and some intro point information as
well.
