When a directory request fails, we flag the relay as non Running so we
don't use it anymore.
This can be problematic with onion services because there are cases
where a tor instance could have a lot of services, ephemeral ones, and
keeps failing to upload descriptors, let say due to a bad network, and
thus flag a lot of nodes as non Running which then in turn can not be
used for circuit building.
This commit makes it that we never flag nodes as non Running on a onion
service directory request (upload or fetch) failure as to keep the
hashring intact and not affect other parts of tor.
Fortunately, the onion service hashring is _not_ selected by looking at
the Running flag but since we do a 3-hop circuit to the HSDir, other
services on the same instance can influence each other by removing nodes
from the consensus for path selection.
This was made apparent with a small network that ran out of nodes to
used due to rapid succession of onion services uploading and failing.
See #40434 for details.

Typos found with codespell.
Please keep in mind that this should have impact on actual code

This is an automated commit made with a python script.
After running the automated script, I had to hand-revert the cases where it
made the conversion functions call themselves.
Additionally, I had to edit a variable declaration in control_bootstrap.c so
that the result of a const cast could be put in a const field.
Some ".c" files define *_PRIVATE macros, but those macros are
not used in any header file. Delete them.
These changes were created using the "make autostyle" from
32522, and then split into commits.
All of these files contain "*.h", except for:
* src/app/config/.may_include
* src/test/.may_include
which also contain "*.inc".
This change prevents includes of "*.c" files, and other
unusually named files.

This includes app, core, feature, lib, and tools, but excludes
ext, test, and trunnel.
This was generated by the following shell script:
cd src
for dname in $(find lib core feature app tools -type d |grep -v \\.deps$); do
keyword="$(echo "$dname" |sed -e "s/\//_/" )"
target="${dname}/${keyword}.dox"
echo "$target"
cat <<EOF >"$target"
/**

EOF
git add "$target"
done
First, remove the HSDir mention which should not be in that generic function.
Second, move them to debug() level since they are possible error case.

Before inspecting the p_chan, we must check if the circuit is marked for close
because if it is the case, the channels are nullified from the circuit.
Several valid cases can mark the circuit for close of the directory
connection.

This commit won't build yet -- it just puts everything in a slightly
more logical place.
The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature". The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.
This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all. That
will have to come in the future.
We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
