This aims to complete our test framework BDB parser to reflect
our read-only BDB parser in the wallet codebase. This could be
useful both for making review of #26606 easier and to also possibly
improve our functional tests for the BDB parser by comparing with
an alternative implementation.

Let's say an attacker wants to use/exhaust the network's bandwidth, and
has the choice between renting resources from a commercial provider and
getting the network to "spam" itself it by sending unconfirmed
transactions. We'd like the latter to be more expensive than the former.
The bandwidth for relaying a transaction across the network is roughly
its serialized size (plus relay overhead) x number of nodes. A 1000vB
transaction is 1000-4000B serialized. With 100k nodes, that's 0.1-0.4GB
If the going rate for commercial services is 10c/GB, that's like 1-4c per kvB
of transaction data, so a 1000vB transaction should pay at least $0.04.
At a price of 120k USD/BTC, 100sat is about $0.12. This price allows us
to tolerate a large decrease in the conversion rate or increase in the
number of nodes.

Use a virtual size of 1000 to keep precision when using a feerate
(which is rounded to the nearest satoshi per kvb) that isn't just an
integer.

Back when we implemented coin age priority as a miner policy, miners
mempools might admit transactions paying very low fees, but then want to
set a higher fee for block inclusion. However, since coin age priority
was removed in v0.15, the block assembly policy is solely based on fees,
so we do not need to apply minimum feerate rules in multiple places. In
fact, the block assembly policy ignoring transactions that are added to
the mempool is likely undesirable as we waste resources accepting and
storing this transaction.
Instead, rely on mempool policy to enforce a minimum entry feerate to
the mempool (minrelaytxfee). Set the minimum block feerate to the
minimum non-zero amount (1sat/kvB) so it collects everything it finds in
mempool into the block.

Tor inbound connections do not reveal the peer's actual network address.
Therefore do not apply whitelist permissions to them.

The `SHA256AutoDetect` return output is used, among other use cases, to
name benchmarks. Using a comma breaks the CSV output.
This change replaces the comma with a semicolon, which fixes the issue.

These jobs can use reduced runner size to avoid wasting CPU, as much of
the long-running part of the job is single-threaded.

Docker currently warns that we are missing a default value.
Set this to scratch which will error if an appropriate image tag is not
passed in to silence the warning.

Previously jobs were running on a large multi-core server where 10 jobs
as default made sense (or may even have been on the low side).
Using hosted runners with fixed (and lower) numbers of vCPUs we should
adapt compilation to match the number of cpus we have dynamically.
This is cross-platform compatible with macos and linux only.

When using hosted runners in combination with cached docker images,
there is the possibility that the host runner image is updated,
rendering the linux-headers package (stored in the cached docker image)
incompatible.
Fix this by doing a re-install of the headers package in
03_test_script.sh.
If the underlying runner kernel has not changed thie has no effect, but
prevents the job from failing if it has.

To remove multiple occurances of the respository name, against which we
compare `${{ github.repository }}` to check if we should use Cirrus
Runners, introduce a helper job which can check a single environment
variable and output this as an input to subsequent jobs.
Forks can maintain a trivial patch of their repo name against the
`REPO_USE_CIRRUS_RUNNERS` variable in ci.yml if they have Cirrus Runners
of their own, which will then enable cache actions and docker build
cache to use Cirrus Cache.
It's not possible to use `${{ env.USE_CIRRUS_RUNNERS }}` in the
`runs-on:` directive as the context is not supported by GitHub.
If it was, this job would no longer be necessary.

Whilst the action cirruslabs/actions/cache will automatically set this
host, the docker `gha` build cache backend will not be aware of it.
Set the value here, which will later be used in the docker build args to
enable docker build cache on the cirrus cache.

This rebase also includes part of e87429a2d0f23eb59526d335844fa5ff5b50b21f
adding `$DOCKER_BUILD_CACHE_ARG \` to the `docker build` command.
Using buildx is required to properly load the correct driver, for use
with registry caching. Neither build, nor BUILDKIT=1 currently do this
properly.
Use of `docker buildx build` is compatible with podman.

Another action to reduce boilerplate in the main ci.yml file.
This action will set up a docker builder compatible with caching build
layers to a container registry using the `gha` build driver.
It will then configure the docker build cache args.
