a2c034d8f5 dos: Apply circuit creation defenses if circ max queue cell reached

c56980f5e5 use consensus ip:port for dir auths if different 
Directory authorities and relays now interact properly with directory
authorities if they change addresses. In the past, they would continue
to upload votes, signatures, descriptors, etc to the hard-coded address
in the configuration. Now, if the directory authority is listed in
the consensus at a different address, they will direct queries to this
new address.

Specifically, these three activities have changed:

* Posting a vote, a signature, or a relay descriptor to all the dir auths.

* Dir auths fetching missing votes or signatures from all the dir auths.

* Dir auths fetching new descriptors from a specific dir auth when they
just learned about them from that dir auth's vote.

We already do this desired behavior (prefer the address in the consensus,
but fall back to the hard-coded dirservers info if needed) when fetching
missing certs.

There is a fifth case, in router_pick_trusteddirserver(), where clients
and relays are trying to reach a random dir auth to fetch something. I
left that case alone for now because the interaction with fallbackdirs
is complicated.

Implements ticket 40705.

bab8375ef5 dir auths now omit Measured= if rs->is_authority 
Directory authorities stop voting a consensus "Measured" weight
for relays with the Authority flag. Now these relays will be
considered unmeasured, which should reserve their bandwidth
for their dir auth role and minimize distractions from other roles.

In place of the "Measured" weight, they now include a
"MeasuredButAuthority" weight (not used by anything) so the bandwidth
authority's opinion on this relay can be recorded for posterity.

Resolves ticket 40698.

e531d4d1b9 Fix a completely wrong calculation in mach monotime_init_internal() 
Bug 1: We were purporting to calculate milliseconds per tick, when we
*should* have been computing ticks per millisecond.

Bug 2: Instead of computing either one of those, we were _actually_
computing femtoseconds per tick.

These two bugs covered for one another on x86 hardware, where 1 tick
== 1 nanosecond.  But on M1 OSX, 1 tick is about 41 nanoseconds,
causing surprising results.

Fixes bug 40684; bugfix on 0.3.3.1-alpha.

d09414858e Properly compute cell-drop overload fraction 
Patch to address #40673. An additional check has been added to
onion_pending_add() in order to ensure that we avoid counting create
cells from clients.

In the cpuworker.c assign_onionskin_to_cpuworker
method if total_pending_tasks >= max_pending_tasks
and channel_is_client(circ->p_chan) returns false then
rep_hist_note_circuit_handshake_dropped() will be called and
rep_hist_note_circuit_handshake_assigned() will not be called. This
causes relays to run into errors due to the fact that the number of
dropped packets exceeds the total number of assigned packets.

To avoid this situation a check has been added to
onion_pending_add() to ensure that these erroneous calls to
rep_hist_note_circuit_handshake_dropped() are not made.

See the #40673 ticket for the conversation with armadev about this issue.

d48eaff86d ignore families for L2 guard independence 
mike is concerned that we would get too much exposure to adversaries,
if we enforce that none of our L2 guards can be in the same family.

this change set now essentially finishes the feature that commit a77727cdc
was attempting to add, but strips the "_and_family" part of that plan.

8e7bd96362 Fix a check, make a netflow padding function more safe. 
Previously, `channelpadding_get_netflow_inactive_timeout_ms` would
crash with an assertion failure if `low_timeout` was greater than
`high_timeout`. That wasn't possible in practice because of checks
in `channelpadding_update_padding_for_channel`, but it's better not
to have a function whose correctness is this tricky to prove.

0eb21427c9 Don't add redundant quotes with escaped() in log messages. 
The escaped() function and its kin already wrap their output in
quotes: there's no reason to do so twice.

I am _NOT_ making a corresponding change in calls that make the same
mistake in controller-related functions, however, due to the risk of
a compatibility break. :(

Closes #22723.
