Rotate to a new L2 vanguard whenever an existing one loses the
Stable or Fast flag. Previously, we would leave these relays in the
L2 vanguard list but never use them, and if all of our vanguards
end up like this we wouldn't have any middle nodes left to choose
from so we would fail to make onion-related circuits.
Fixes bug 40805; bugfix on 0.4.7.1-alpha.

This addresses issue #40800 and a couple other problems I noticed while
trying to reproduce that one.
The original issue is just a missing cast to void* on the args of
__builtin___clear_cache(), and clang is picky about the implicit cast
between what it considers to be char of different signedness. Original
report is from MacOS but it's also reproducible on other clang targets.
The cmake-based original build system for equix and hashx was a handy
way to run tests, but it suffered from some warnings due to incorrect
application of include_directories().
And lastly, there were some return codes from hashx_exec() that get
ignored on equix when asserts are disabled. It bugged me too much to
just silence this with a (void) cast, since even though this is in the
realm of low-likelyhood programming errors and not true runtime errors, I
don't want to make it easy for the hashx_exec() wrappers to return
values that are dangerously wrong if an error is ignored. I made sure
that even if asserts are disabled, we return values that will cause the
solver and verifier to both fail to validate a potential solution.

This fixes an "initializer is not a constant" compilation error that manifests
itself on gcc versions < 8.1 and MSVC (see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69960#c18).

The MR was using an old function definition so the code fix is for that.

This adds 2 histogram metrics for hidden services:
* `tor_hs_rend_circ_build_time` - the rendezvous circuit build time in milliseconds
* `tor_hs_intro_circ_build_time` - the introduction circuit build time in milliseconds
The text representation representation of the new metrics looks like this:
```
# HELP tor_hs_rend_circ_build_time The rendezvous circuit build time in milliseconds
# TYPE tor_hs_rend_circ_build_time histogram
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="1000.00"} 2
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="5000.00"} 10
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="10000.00"} 10
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="30000.00"} 10
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="60000.00"} 10

This adds a `reason` label to the `hs_intro_rejected_intro_req_count` and
`hs_rdv_error_count` metrics introduced in #40755.
Metric look up and intialization is now more a bit more involved. This may be
fine for now, but it will become unwieldy if/when we add more labels (and as
such will need to be refactored).
Also, in the future, we may want to introduce finer grained `reason` labels.
For example, the `invalid_introduce2` label actually covers multiple types of
errors that can happen during the processing of an INTRODUCE2 cell (such as
cell parse errors, replays, decryption errors).

This introduces a couple of new service side metrics:
* `hs_intro_rejected_intro_req_count`, which counts the number of introduction
requests rejected by the hidden service
* `hs_rdv_error_count`, which counts the number of rendezvous errors as seen by
the hidden service (this number includes the number of circuit establishment
failures, failed retries, end-to-end circuit setup failures)
Closes #40755. This partially addresses #40717.

Directory authorities now include their AuthDirMaxServersPerAddr
config option in the consensus parameter section of their vote. Now
external tools can better predict how they will behave.
In particular, the value should make its way to the
https://consensus-health.torproject.org/#consensusparams page.
Once enough dir auths vote this param, they should also compute a
consensus value for it in the consensus document. Nothing uses this
consensus value yet, but we could imagine having dir auths consult it
in the future.
Implements ticket 40753.
