Simplify handle_control_getinfo() by using the new reply lines
abstraction. Previously, this function explicitly checked for whether
it should generate a MidReplyLine, a DataReplyLine, or an
EndReplyLine. control_write_reply_lines() now abstracts this check.

In handle_control_getconf(), use the new control reply line
abstraction to simplify output generation. Previously, this function

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.

- 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.

Old and messy code path. Structure it in a more pleasant and readable way. No
behavior change with this refactor.

The FP_ identifiers referred to fingerprints, but they also applied
to address ranges. The router_status_t name invited confusion with
routerstasus_t. Fixes ticket 29826.

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.

We now keep descriptor that we can't decode due to missing client
authorization in the cache.
This new function is used when new client authorization are added and to tell
the client cache to retry decoding.

This commit extract most of the code that dirclient.c had to handle the end of
a descriptor directory requests (fetch). It is moved into hs_client.c in order
to have one single point of entry and the rest is fully handled by the HS
subsystem.
As part of #30382, depending on how the descriptor ended up stored (decoded or
not), different SOCKS error code can be returned.

This will allow us to callback into the HS subsytem depending on the decoding
status and return an extended SOCKS5 error code depending on the decoding
issue.
This is how we'll be able to tell the SocksPort connection if we are missing
or have bad client authorization for a service.

We now keep the descriptor in the cache, obviously not decoded, if it can't be
decrypted for which we believe client authorization is missing or unusable
(bad).
This way, it can be used later once the client authorization are added or
updated.
