* 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.
Closes#25163

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.

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.
Fixes#25148

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.

This patch makes the wording around error cases for selecting an entropy
source in Tor slightly more verbose. We also let the user know when
something goes wrong that we are trying out a fallback method instead.

Included crypto_rsa.[ch] into include.am in order to resolve a compiling issue.
Follows #24658.
Signed-off-by: Fernando Fernandez Mancera <ffmancera@riseup.net>
crypto_get_rsa_padding_overhead() and crypto_get_rsa_padding() are
not static inline anymore in order to split the crypto_rsa module
from crypto.[ch].
Also included necessary modules in order to solve dependency issues.
Also made two functions in crypto.c use crypto_pk_asn1_encdoe()
instead of reaching into the crypto_pk_t struct.
