This fixes a serious bug in our hsdir set change logic:
We used to add nodes in the list of previous hsdirs everytime we
uploaded to a new hsdir and we only cleared the list when we built a new
descriptor. This means that our prev_hsdirs list could end up with 7
hsdirs, if for some reason we ended up uploading our desc to 7 hsdirs
before rebuilding our descriptor (e.g. this can happen if the set of
hsdirs changed).
After our previous hdsir set had 7 nodes, then our old algorithm would
always think that the set has changed since it was comparing a smartlist
with 7 elements against a smartlist with 6 elements.
This commit fixes this bug, by clearning the prev_hsdirs list before we
upload to all hsdirs. This makes sure that our prev_hsdirs list always
contains the latest hsdirs!
Since ssize_t is signed and might be 64 bits, we should use
tt_i64_op to make sure it's positive. Otherwise, if it is negative,
and we use tt_u64_op, we'll be treating it as a uint64_t, and we
won't detect negative values.
This fixes CID 1416338 and 1416339. Bug not in any released Tor.
We refactor the descriptor reupload logic to be similar to the v2 logic
where we update a global 'consider_republishing_rend_descriptors' flag
and then we use that to check for hash ring changes during the global
hidden service callbacks.
This fixes bugs where we would inspect the hash ring immediately as we
receive new dirinfo (e.g. consensus) but before running the hidden
service housekeeping events. That was leaving us in an inconsistent
state wrt hsdir indices and causing bugs all around.
The `test-operator-cleanup` patch, and related coccinelle patches,
don't do any checks for line length. This patch fixes the line
length issues caused by the previous commits.
This patch fixes the operator usage in src/test/*.c to use the symbolic
operators instead of the normal C comparison operators.
This patch was generated using:
./scripts/coccinelle/test-operator-cleanup src/test/*.[ch]
Only register the RP circuit when it opens and not when we send the INTRODUCE1
cell else, when re-extending to a new IP, we would register the same RP
circuit with the same cookie twice leading to the circuit being closed.

We can't trigger a valid upload because it would require us to MOCK a long
list of functions ultimately not really testing the upload because we aren't
on a running network.

Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1. I've turned it
into an 'unsigned' bitfield, and inverted its sense. I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.
I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.
This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.
Later I'm going to add more flags, for ed25519 support.
We need this func so that we recognize SOCKS conns to v3 addresses.
- Also rename rend_valid_service_id() to rend_valid_v2_service_id()
- Also move parse_extended_hostname() tests to their own unittest, and
add a v3 address to the test as well.

We want to reupload our descriptor if its set of responsible HSDirs
changed to minimize reachability issues.
This patch adds a callback everytime we get new dirinfo which checks if
the hash ring changed and reuploads descriptor if needed.
Use the PATH_SEPARATOR for a path comparaison so it works with Windows as
well.

"check_after_deref: Null-checking items suggests that it may be null,
but it has already been dereferenced on all paths leading to the
check."
