This approach saves us a pair of curve25519 operations for every
subcredential but the first. It is not yet constant-time.
I've noted a few places where IMO we should refactor the code so
that the complete list of subcredentials is passed in earlier.
At this commit, the service reads the config file and parse it to finally set
the service config object with the options.

The hs_parse_address() can not be used without an options_t object existing
since on error it uses the escaped_safe_str() that looks at the options.
This new function won't log and returns an error message in case of failure
that can then be used to log.

Some ".c" files define *_PRIVATE macros, but those macros are
not used in any header file. Delete them.
These changes were created using the "make autostyle" from
32522, and then split into commits.
With v3, the "pending_final_cpath" of a circuit is always NULL which means
that for v3, established client rendezvous circuit waiting for the intro point
to ACK, will always end up timing out quickly.
This can increase the delays to which you connect to a service since in order
to succeed, the rendezvous circuit needs to fully established
(CIRCUIT_PURPOSE_C_REND_JOINED) within the cutoff of the introduction circuit
as well which is these days around 2-3 seconds.

All of these files contain "*.h", except for:
* src/app/config/.may_include
* src/test/.may_include
which also contain "*.inc".
This change prevents includes of "*.c" files, and other
unusually named files.
Part of 32609.
- Remove key_dir which is useless.
- Kill an indentation layer.
We want to make it cleaner and slimmer so that we can reuse parts of it in the
REMOVE command for removing the right client auth file.
Because the function that parses client auth credentials saved on
disk (parse_auth_file_content()) is not future compatible, there is no way to
add support for storing the nickname on the disk. Hence, nicknames cannot
persist after Tor restart making them pretty much useless.
In the future we can introduce nicknames by adding a new file format for client
auth credentials, but this was not deemed worth doing at this stage.
- See hs_client_register_auth_credentials() for the entry point.
- Also set the permanent flag for credentials we read from the filesystem.
- Also add some missing documentation.
Since the removal of ip->circuit_established, this function does litterally
nothing so clean it up.

By centralizing the circuit cleanup type that is: on close, free and
repurpose, some actions on the circuit can not happen for a certain cleanup
type or for all types.
This passes a cleanup type so the HS subsystem (v2 and v3) can take actions
based on the type of cleanup.
For instance, there is slow code that we do not run on a circuit close but
rather only on free.

Report back to the v3 subsystem any introduction point client circuit failure
so they can be noted down in the failure cache.

Refactor to decomplexify circuit_about_to_free() and finally have one single
entry point into the HS subsystems (v2 and v3) for when a circuit is freed.
With this, hs_circ_cleanup() becomes the one and only entry point when a
circuit is freed which then routes to the right subsystem version for any
actions to be taken.
This moves a big chunk of code from circuituse.c to rendclient.c. No behavior
change. Next commit will refactor it to reduce our technical debt.
