* FIXES#25127: https://bugs.torproject.org/25127
* ADDS a new module to the Rust tor_util crate for small utilities
for working with static strings between languages.
* CHANGES the return type of protover_compute_for_old_tor to point to
immutable data.
* CHANGES the code from the previous commit to use the new static
string utilities.
At this commit, the SocksSocketsGroupWritable option is renamed to
UnixSocksGroupWritable. A deprecated warning is triggered if the old option is
used and tor will use it properly.

On slow system, 1 msec between one read and the other was too tight. For
instance, it failed on armel with a 4msec gap:
https://buildd.debian.org/status/package.php?p=tor&suite=experimental
Increase to 10 msec for now to address slow system. It is important that we
keep this OP_LE test in so we make sure the msec/usec/nsec read aren't
desynchronized by huge gaps. We'll adjust again if we ever encounter a system
that goes slower than 10 msec between calls.

Remove a series of connection counters that were only used when dumping the
rephist statistics with SIGUSR1 signal.
This reduces the or_history_t structure size.

This removes the code that tracks the extend attemps a client makes. We don't
use it and it was only used to provide statistics on a SIGUSR1 from the
rephist dump stats function.

Since we're making it so that unstable zstd apis can be disabled,
we need to test them. I do this by adding a variant setup/cleanup
function for the tests, and teaching it about a fake compression
method called "x-zstd:nostatic".
Services can keep rendezvous circuits for a while so don't log them if tor is
a single onion service.

The HT_FOREACH() is insanely heavy on the CPU and this is part of the fast
path so make it return the nice memory size counter we added in
4d812e29b9.

Included crypto_digest.[ch] into include.am in order to solve a compiling
issue. Also EOF line in crypto_digest.c added.
Follows #24658.

Included crypto_digest.h in some files in order to solve xof+digest module
dependency issues. Removed crypto.h where it isn't needed anymore.
Follows #24658.

Add two new files (crypto_digest.c, crypto_digest.h) as new module of
crypto.[ch]. This new module includes all functions and dependencies related
to digest and xof operations. Those have been removed from crypto.[ch].
Follows #24658.

Becasue the circuit creation burst and rate can change at runtime it is
possible that between two refill of a bucket, we end up setting the bucket
value to less than there currently is.

If the cache is using 20% of our maximum allowed memory, clean 10% of it. Same
behavior as the HS descriptor cache.

The current code flow makes it that we can release a channel in a PENDING
state but not in the pending list. This happens while the channel is being
processed in the scheduler loop.
Fixes#25125
Signed-off-by: David Goulet <dgoulet@torproject.org>
This tests many cases of the KIST scheduler with the pending list state by
calling entry point in the scheduler while channels are scheduled or not.
Also, it adds a test for the bug #24700.
