e1c29a769c channel: Remove everything related to queue size
The channel subsystem was doing a whole lot to track and try to predict the
channel queue size but they are gone due to previous commit.

46a0709261 channel: Remove incoming/outgoing queue
For the rationale, see ticket #23709.

This is a pretty massive commit. Those queues were everywhere in channel.c and
it turns out that it was used by lots of dead code.

The channel subsystem *never* handles variable size cell (var_cell_t) or
unpacked cells (cell_t). The variable ones are only handled in channeltls and
outbound cells are always packed from the circuit queue so this commit removes
code related to variable and unpacked cells.

However, inbound cells are unpacked (cell_t), that is untouched and is handled
via channel_process_cell() function.

In order to make the commit compile, test have been modified but not passing
at this commit. Also, many tests have been removed but better improved ones
get added in future commits.

This commit also adds a XXX: which indicates that the handling process of
outbound cells isn't fully working. This as well is fixed in a future commit.

Finally, at this commit, more dead code remains, it will be cleanup in future
commits.

Fixes #23709

bf242ebe6c relay: Remove dead code
append_cell_to_circuit_queue() had code disabled from commit
2a95f31716

This code is 4+ years old related to bug #9072 so if we ever want to revisit
it, lets inspect/revert this commit.

69f93f806c Check number of usable guards when applying md restrictions.
We used to check whether we have enough filtered guards (guard set when
torrc is applied) but that's not good enough, since that might be bad in
some cases where many guards are not reachable (might cause overblocking
and hence reacahbility issues).

We now check if we have enough reachable filtered guards before applying
md restrictions which should prevent overblocking.

3bb29dd707 Correctly handle partial success in consensus diff calculation.
Previously, if store_multiple() reported a partial success, we would
store all the handles it gave us as if they had succeeded.  But it's
possible for the diff to be only partially successful -- for
example, if LZMA failed but the other compressors succeeded.

c8ee12b2e8 Recover better from empty/invalid storagedir files
If we can't read a file because of an FS issue, we say "we can't
read that" and move on.  But if we can't read it because it's empty,
because it has no labels, or because its labels are misformatted, we
should remove it.

981bb60575 circuit: Don't timeout opened C_INTRODUCING circuit
A circuit with purpose C_INTRODUCING means that its state is opened but the
INTRODUCE1 cell hasn't been sent yet. We shouldn't consider that circuit when
looking for timing out "building circuit". We have to wait on the rendezvous
circuit to be opened before sending that cell so the intro circuit needs to be
kept alive for at least that period of time.

This patch makes that the purpose C_INTRODUCING is ignored in the
circuit_expire_building() which means that we let the circuit idle timeout
take care of it if we end up never using it.

Fixes #23681

d45bf0c65c Add an extra check in test_entrynodes

and so the "if (conn)" check will not be redundant, and so coverity
