285632a61b Replace all FREE_AND_NULL* uses to take a type and a free function.
This commit was made mechanically by this perl script:

\#!/usr/bin/perl -w -i -p

next if /^#define FREE_AND_NULL/;
s/\bFREE_AND_NULL\((\w+),/FREE_AND_NULL\(${1}_t, ${1}_free_,/;
s/\bFREE_AND_NULL_UNMATCHED\(/FREE_AND_NULL\(/;

db024adc90 Switch to a safer FREE_AND_NULL implementation
This one only evaluates the input once, so it cannot mess up even if
there are side effects.

025610612d prop224: Directory cache support
This implements the proposal 224 directory descriptor cache store and lookup
functionalities. Furthermore, it merges the OOM call for the HSDir cache with
current protocol v2 and the new upcoming v3.

Add hs_cache.{c|h} with store/lookup API.

Closes #18572

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

edeba3d472 simplify rend_cache_store_status_t back to a boolean
it used to be a tri-state, but now it's just a bi-state, so we can
take out all the machinery like the enum.

5390296338 rip out hid_serv_acting_as_directory()
When we made HidServDirectoryV2 always 1, we removed the situation
where a relay could choose not to be an HSDir. Now simplify the
rest of the code to reflect this decision.

(We have to remove two apparently unrelated free() calls in the unit
tests, since they used to free stuff that we created as a side effect
of calling router_get_my_routerinfo(), and now we no longer call that.)

d47a4aec66 Separate lookup function for service rend cache
Performing lookups in both the client and service side descriptor
caches from the same rend_cache_lookup_entry() function increases the
risk of accidental API misuse.

I'm separating the lookup functions to keep the caches distinct.

335d0b95d3 Clean old descriptors from the service-side rend cache
Parameterize the rend_cache_clean() function to allow it clean
old rendezvous descriptors from the service-side cache as well as
the client descriptor cache.

5dc2cbafef Specify descriptor cache type in rend_cache_lookup_entry()
Adds an Enum which represents the different types of rendezvous
descriptor caches. This argument is passed in each call to
rend_cache_lookup_entry() to specify lookup in the client-side or
service-side descriptor caches.

1a75e6da00 Create a service-side descriptor cache
Adds a service descriptor cache which is indexed by service ID. This
descriptor cache is used to store service descriptors generated by a
local rendevous service.

The service-side cach can be queried by calling rend_cache_lookup_entry()
with the 'service' argument set to 1.

ab9a0e3407 Add rend failure cache
When fetching a descriptor, we know test every introduction points in it
against our rend failure cache to know if we keep it or not. For this to
work, now everytime an introduction points is discareded (ex: receiving a
NACK), we note it down in our introduction cache.

See rendcache.c for a detailed explanation of the cache's behavior.

Fixes #16389

a7624de1aa Move cache objects and functions to rendcache.{c|h}
Every functions and objects that are used for hidden service descriptor
caches are moved to rendcache.{c|h}.

This commit does NOT change anything, just moving code around.

33b1a33c33 Add rendcache.{c|h}
For now, rend_cache_entry_t has been moved from or.h to rendcache.h and
those files have been added to the build system.

In the next commit, these will contain hidden service descriptor cache ABI
and API for both client and directory side. The goal is to consolidate the
descriptor caches in one location to ease development, maintenance, review
and improve documentation for each cache behavior and algorithm.
