5e2318165d Add "stub" files for disabled modules.
These modules are only built when the selected modules are disabled.
The provide stub implementations of the subsystem blocks.  Later,
other stub implementations could move here.

Having real subsystem blocks here will let us handle disabled
configuration options better.

fc32349adc hs-v3: Handle client rendezvous circuit timeout
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.

Fixes #32021

cbc495453c hs-v3: Give a cleanup type to hs_circ_cleanup()
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.

00136c9430 hs-v2: Move v2 circuit cleanup actions into hs_circ_cleanup()
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.

80f241907c hs-v3: Set extended error if .onion is invalid
In order to achieve this, the parse_extended_hostname() had to be refactored
to return either success or failure and setting the hostname type in the given
parameter.

The reason for that is so it can detect invalid onion addresses that is having
a ".onion", the right length but just not passing validation.

That way, we can send back the prop304 ExtendedError "X'F1' Onion Service
Descriptor Is Invalid" to notify the SOCKS connection of the invalid onion
address.

4e4c4e72d7 Handle binary IPv6 addresses and bracketed strings in RESOLVE_PTR.
When a SOCKS5 client sends a RESOLVE_PTR request, it must include
either an IPv4 or IPv6 address.  In the past this was required to be a
binary address (address types 1 or 4), but since the refactoring of
SOCKS5 support in Tor 0.3.5.1-alpha, strings (address type 3) are also
allowed if they represent an IPv4 or IPv6 literal.

However, when a binary IPv6 address is provided,
parse_socks5_client_request converts it into a string enclosed in
brackets.  This doesn't match what string_is_valid_ipv6_address
expects, so this would fail with the error "socks5 received
RESOLVE_PTR command with hostname type. Rejecting."

By replacing string_is_valid_ipv4_address/string_is_valid_ipv6_address
with tor_addr_parse, we accept strings both with and without brackets.
This fixes the handling of binary addresses, and also improves
symmetry with CONNECT and RESOLVE requests.

Fixes bug 32315.
