Simplify ip_address_changed() by removing redundant checks
(all exits are relays, and need to rebuild their descriptor when their
IP addresses change).
Rewrite the function comment, and rename the argument, so the function
is easier to understand and use.
Closes 33091.
Make Tor clients tell dual-stack exits that they prefer IPv6
connections.
This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.
Also update the man page, putting all the IP flags in their
non-default forms.
Closes ticket 32637.

To make Tor still work, we define a minimal dircache_stub.c file
that defines the entry points to the module that can actually be
seen by the compiler when we're building with dircache and relay
disabled.
The variable lenght cells are handled directly by
channel_tls_handle_var_cell() from an OR connection reading its inbuf. The
channel var cell handler (agnostic) was never used.

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.
I've chosen the "AuthDirMaxServersPerAddr" option here for
simplicity, since it is used literally nowhere else besides the dirauth
module. Once we have all the infrastructure in place for this, we
can move more options into this structure.
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.
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.

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.
