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.

Closes #32892

Now that these tests are skipped on windows _and_ android, we should
name the macro that skips them after the functionality that the
tests depend on.

Closes last part of 32825.

When TOR_DISABLE_PRACTRACKER is set, print a message to
stderr when skipping practracker checks.

Part of 32705.

When practracker is disabled, its output will be empty.  We don't
want that happening during our tests.

Fixes bug 32705; bugfix on 0.4.2.1-alpha, when test_practracker.sh
was introduced.

Move ReducedCircuitPadding and ReducedConnectionPadding immediately
after the corresponding non-Reduced options.  Part of ticket 32846.

Only directory authorities use the GuardfractionFile option, so move
it to that section.  Part of ticket 32846.

Alphabetize client options in tor.1.txt.  Closes ticket32846.

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.

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.

kludgey perl script. It results in a number of wide lines, which
I'll clean up in a subsequent commit.

This will help avoid wide lines in our output.

This is going to make my script happier; these lines will soon
disappear.

When these macros aren't defined, the expansions of the NS macros
can get particularly ugly.

We use bool, so we should include stdbool.

This frees us from a dependency on include order.

This change means that authmode.h no longer needs to see
or_options_t, and frees us from an ordering dependency.

Without this change, compilation success depends on include order in
several tricky ways.

This prevents a dependency on include order.

This fixes a case where our compilation would depend on include order.
