Cleanup some bugs discovered during 23576:
* stop copying the first 20 characters of a 40-character hex string
to a binary fingerprint
* stop putting IPv6 addresses in a variable called "ipv4"
* explain why we do a duplicate tt_int_op() to deliberately fail and
print a value
Fixes bug 29243; bugfix on 0.3.2.1-alpha.
The previous commits for 23576 confused hs_desc_link_specifier_t
and link_specifier_t. Removing hs_desc_link_specifier_t fixes this
confusion.
Fixes bug 22781; bugfix on 0.3.2.1-alpha.
One HSv3 unit test used "tor_memeq()" without checking the return value. This
commit changes that to use "tt_mem_op()" to actually make the test validate
something :).

Return a newly allocated fake client authorization object instead of taking
the object as a parameter.

Previously, we encrypted the descriptor without the descriptor cookie. This
commit, when the client auth is enabled, the descriptor cookie is always used.
I also removed the code that is used to generate fake auth clients because it
will not be used anymore.

This patch fixes a memory leak in hs_helper_build_hs_desc_impl() where
if a test assertion would fail we would leak the storage that `desc`
points to.

This patch fixes a potential memory leak in
hs_helper_build_intro_point() where a `goto done` is called before the
`intro_point` variable have been assigned to the value of the `ip`
variable.

We enrich the test_client_cache() test in two ways:
a) We check that transitioning time periods also cleans up expired
descriptors in client memory.
b) We test hs_cache_lookup_as_client() instead of
lookup_v3_desc_as_client(). The former is a higher level function
which calls the latter and allows us to test deeper into the
subsystem.
We used to use NULL subcredential which is a terrible terrible idea. Refactor
HS unittests to use subcredentials.
Also add some non-fatal asserts to make sure that we always use subcredentials
when decoding/encoding descs.

Add a new and free function for hs_desc_intro_point_t so the service can use
them to setup those objects properly.

A descriptor only contains the curve25519 public key in the enc-key field so
the private key should not be in that data structure. The service data
structures will have access to the full keypair (#20657).
Furthermore, ticket #21871 has highlighted an issue in the proposal 224 about
the encryption key and legacy key being mutually exclusive. This is very wrong
and this commit fixes the code to follow the change to the proposal of that
ticket.

Create the hs_test_helpers.{c|h} files that contains helper functions to
create introduction point, descriptor and compare descriptor.
Used by both the hs cache and hs descriptor tests. Unify them to avoid code
duplication.
Also, this commit fixes the usage of the signing key that was wrongly used
when creating a cross signed certificate.
