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.

23c77f79fd Remove all usage of the NS*() macros in test*.c 
This is an automatically generated commit, made with the following
kludgey perl script. It results in a number of wide lines, which
I'll clean up in a subsequent commit.

1ffba2f121 Always define NS_MODULE and NS_SUBMODULE when NS is used. 
When these macros aren't defined, the expansions of the NS macros
can get particularly ugly.
