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.

68c21860e3 Add another assertion to check for 24086 root causes
In cdm_diff_ht_set_status(), we shouldn't have been allowing the
status CDM_DIFF_PRESENT to be set if there wasn't actually a handle.

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.

Fixes bug 24086; bugfix on 0.3.1.1-alpha.

49f21b6ba3 control: Support HSv3 interface for ADD_ONION
At this commit, the key handling and generation is supported for a v3 service
(ED25519-V3). However, the service creation is not yet implemented. This only
adds the interface and code to deal with the new ED25519-V3 key type.

Tests have been updated for RSA key type but nothing yet for ED25519-v3.

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

95238eb917 Fix a traceback when closing a blocked connection "immediately".
When we close a connection via connection_close_immediately, we kill
its events immediately. But if it had been blocked on bandwidth
read/write, we could try to re-add its (nonexistent) events later
from connection_bucket_refill -- if we got to that callback before
we swept the marked connections.

Fixes bug 24167.  Fortunately, this hasn't been a crash bug since we
introduced connection_check_event in 0.2.9.10, and backported it.

This is a bugfix on commit 89d422914a, I believe, which
appeared in Tor 0.1.0.1-rc.

192be00691 Make the DataDirectory option immutable.
By convention, the torrc options that the user sets are
unchangeable.  If we need to change them, we should be using a copy
that's stored in another field

To avoid trouble, I'm keeping DataDirectory as the name for the
field that the rest of Tor uses, and using DataDirectory_option for
the confparse-controlled field.

This commit also modernizes some older string handling code in the
DataDirectory normalization function.
