773bcf5629 Move dirclient-related functions out of dirserv, and reenable them

8a0c739467 Disable feature/dircache files when dircache module is disabled.
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.

ca9a5390ff Don't escape the bridge distribution value.
We already check if there are invalid values in
check_bridge_distribution_setting() and reject the value if that is the
case. We can therefore only have strings of [A-Z] | [a-z] | [0-9] | '-'
| '_' here which is according to the directory specification.

3f20a69afb Always escape BridgeDistribution value from torrc in descriptors.
When the BridgeDistribution value was added in commit
ebab521525 the check for whether the value
contains '\n' or '\r' was added as a requirement for whether or not the
value should be escaped.

This patch removes this check and makes sure we call `escaped()` on the
value every time before we add it to a descriptor.

77246dc0d8 Tell static analyzer that having ntservice functions not exist is ok
When we made these functions exist unconditionally (as macros on
non-windows platforms), we started to get a dead-code warning on
Coverity.  We now use a macro to tell coverity not to worry about
this particular dead-code instance.

5e27caa60c compat_compiler: add a macro to prevent coverity deadcode warnings.
The POSSIBLE(e) macro evaluates to the value of (e), but does so in
a way that a static analyzer will not conclude that (e) is
impossible.  We can use this when we expect our regular compilers to
eliminate deadcode, but we don't want coverity to complain about it.

Part of a fix for 32960.

59dac38ebe chan: Remove dead var cell handler from channel_t
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.

165a92e33f Replace an assertion with a check-and-log
We hit this assertion with bug 32868, but I'm stymied figuring out
how we wound up with a routerstatus like this.  This patch is a
diagnostic to attempt to figure out what is going on, and to avoid a
crash in the meantime.

bbe90e3ec1 hs-v2: Always check rend_cache validity before using it
When looking up an entry in the rend_cache, stop asserting that it exists but
rather confirm it exists and if not, return that no entry was found.

The reason for that is because the hs_circ_cleanup_on_free() function (which
can end up looking at the rend_cache) can be called from the
circuit_free_all() function that is called _after_ the rend cache is cleaned
up in tor_free_all().

We could fix the free all ordering but then it will just hide a future bug.
Instead, handle a missing rend_cache as a valid use case as in while we are in
the cleanup process.

As Tor becomes more modular, it is getting more and more difficult to ensure
subsystem callstack ordering thus this fix aims at making the HSv2 subsystem
more robust at being called while tor is pretty much in any kind of state.

Fixes #32847.

42c6fc851e Remove NS*() macros from test.h.
We never used them very much, and although they had potential to
clarify some of our tests, they also made some of the logic harder
for people to follow.  Clang-format can't make head or tail of them,
so the time has come to say goodbye to them.
