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.

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.

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.

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.
This reverts commit 9a06282546.
It appears that I misunderstood how the seccomp2 filter rules
interact. It appears that `SCMP_ACT_ERRNO()` always takes
precedence over `SCMP_ACT_ALLOW()` -- I had thought instead that
earlier rules would override later ones. But this change caused bug
25115 (not in any released Tor).
The accurate address of a connection is real_addr, not the addr member.
channel_tls_get_remote_addr_method() now returns real_addr instead.
Fixes#24952; bugfix on 707c1e2 in 0.2.4.11-alpha.

Tor preemptiely builds circuits and they can be cannibalized later in their
lifetime. A Guard node can become unusable (from our guard state) but we can
still have circuits using that node opened. It is important to not pick those
circuits for any usage through the cannibalization process.

These are no longer meaningful, since there's no longer an upper
limit to how many times (in the exponential-backoff world) one can
retry a download. download_status_is_ready() didn't check these any
more, and neither do we.
