ab35f9de46 Correctly close intro circuit when deleting ephemeral HS
When deleting an ephemeral HS, we were only iterating on circuit with an
OPEN state. However, it could be possible that an intro point circuit didn't
reached the open state yet.

This commit makes it that we close the circuit regardless of its state
except if it was already marked for close.

Fixes #18604

c7f1b46a10 Perform cache lookup when FetchHidServDescriptors is set
The FetchHidServDescriptors check was placed before the descriptor cache
lookup which made the option not working because it was never using the
cache in the first place.

4c90cdc0e7 Coverity dislikes (double) (int/int).
When you divide an int by an int and get a fraction and _then_ cast
to double, coverity assumes that you meant to cast to a double
first.

In my fix for -Wfloat-conversion in 493499a339, I
did something like this that coverity didn't like.

Instead, I'm taking another approach here.

Fixes CID 1232089, I hope.

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.

8f2d2933f9 Use -Wdouble-promotion in GCC >= 4.6
This warning triggers on silently promoting a float to a double.  In
our code, it's just a sign that somebody used a float by mistake,
since we always prefer double.

4f8086fb20 Enable -Wnull-dereference (GCC >=6.1), and fix the easy cases
This warning, IIUC, means that the compiler doesn't like it when it
sees a NULL check _after_ we've already dereferenced the
variable. In such cases, it considers itself free to eliminate the
NULL check.

There are a couple of tricky cases:

One was the case related to the fact that tor_addr_to_in6() can
return NULL if it gets a non-AF_INET6 address.  The fix was to
create a variant which asserts on the address type, and never
returns NULL.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

9cf6af76eb Fix a double-free bug in routerlist_reparse_old
I introduced this bug when I moved signing_key_cert into
signed_descriptor_t. Bug not in any released Tor.  Fixes bug 19175, and
another case of 19128.

Just like signed_descriptor_from_routerinfo(), routerlist_reparse_old()
copies the fields from one signed_descriptor_t to another, and then
clears the fields from the original that would have been double-freed by
freeing the original.  But when I fixed the s_d_f_r() bug [#19128] in
50cbf22099, I missed the fact that the code was duplicated in
r_p_o().

Duplicated code strikes again!

For a longer-term solution here, I am not only adding the missing fix to
r_p_o(): I am also extracting the duplicated code into a new function.

Many thanks to toralf for patiently sending me stack traces until
one made sense.

50cbf22099 Fix a bug related to moving signing_key_cert
Now that the field exists in signed_descriptor_t, we need to make
sure we free it when we free a signed_descriptor_t, and we need to
make sure that we don't free it when we convert a routerinfo_t to a
signed_descriptor_t.

But not in any released Tor. I found this while working on #19128.

One problem: I don't see how this could cause 19128.
