5b03c7ba6d Fix check_expired_networkstatus_callback() if condition
The condition was always true meaning that we would reconsider updating our
directory information every 2 minutes.

If valid_until is 6am today, then now - 24h == 1pm yesterday which means that
"valid_until < (now - 24h)" is false. But at 6:01am tomorrow, "valid_until <
(now - 24h)" becomes true which is that point that we shouldn't trust the
consensus anymore.

Fixes #23091

ff9c529667 hs: Cleanup logging statement in hs_intropoint.c
One log statement was a warning and has been forgotten. It is triggered for a
successful attempt at introducting from a client.

It has been reported here:
https://lists.torproject.org/pipermail/tor-relays/2017-August/012689.html

Three other log_warn() statement changed to protocol warning because they are
errors that basically can come from the network and thus triggered by anyone.

Fixes #23078.

6c8c973191 Rename the hybrid_encrypt/decrypt functions; label them as dangerous
We need to keep these around for TAP and old-style hidden services,
but they're obsolete, and we shouldn't encourage anyone to use them.
So I've added "obsolete" to their names, and a comment explaining
what the problem is.

750c684fff prop224: Don't use an array of config handlers
As per nickm suggestion, an array of config handlers will not play well with
our callgraph tool.

Instead, we'll go with a switch case on the version which has a good side
effect of allowing us to control what we pass to the function intead of a fix
set of parameters.

At this commit, we have 100% code coverage of hs_config.c.

f76f873199 prop224: Add a function to check for invalid opts
Every hidden service option don't apply to every version so this new function
makes sure we don't have for instance an option that is only for v2 in a v3
configured service.

This works using an exclude lists for a specific version. Right now, there is
only one option that is not allowed in v3. The rest is common.

c086a59ea1 prop224: Configure v3 service from options
This commit adds the support in the HS subsystem for loading a service from a
set of or_options_t and put them in a staging list.

To achieve this, service accessors have been created and a global hash map
containing service object indexed by master public key. However, this is not
used for now. It's ground work for registration process.

765ed5dac1 prop224: Add a init/free_all function for the whole subsystem
Introduces hs_init() located in hs_common.c which initialize the entire HS v3
subsystem. This is done _prior_ to the options being loaded because we need to
allocate global data structure before we load the configuration.

The hs_free_all() is added to release everything from tor_free_all().

Note that both functions do NOT handle v2 service subsystem but does handle
the common interface that both v2 and v3 needs such as the cache and
circuitmap.

02e2edeb33 prop224: Add hs_config.{c|h} with a refactoring
Add the hs_config.{c|h} files contains everything that the HS subsystem needs
to load and configure services. Ultimately, it should also contain client
functions such as client authorization.

This comes with a big refactoring of rend_config_services() which has now
changed to only configure a single service and it is stripped down of the
common directives which are now part of the generic handler.

This is ground work for prop224 of course but only touches version 2 services
and add XXX note for version 3.
