`test_framework.py` already uses `PREVIOUS_RELEASES_DIR` to set a
default directory to find previous releases, so should
`get_previous_releases.py` when fetching them.
This is more convenient for local development when using multiple
worktrees where having `$PREVIOUS_RELEASES_DIR` set is useful.
Also allows some CI code to get deleted.
ea59f17220 test: cover v0.14.3 wallet migration (w0xlt)
18b8afd093 test: support v0.14.x in dumb_sync_blocks (w0xlt)
Pull request description:
This PR adds test coverage for migrating legacy Bitcoin Core wallets from v0.14.3 (released in 2017) to the descriptor wallet format. The test validates that users can safely upgrade their wallets while preserving all funds, transaction history, and addresses.
This test was originally developed on top of #32977, as it was requested in reviews.
However, since it also increases test coverage, it can be merged independently.
The test covers two wallet migration scenarios:
* Non-HD Wallet Migration - Tests migration of non-HD wallets (created with `-usehd=0`)
* Single Chain HD Wallet Migration - Tests migration of HD wallets from v0.14.3 (`VERSION_HD_BASE`)
The node v0.14.3 cannot be synced using the normal test framework helpers because it does not have the `syncwithvalidationinterfacequeue` RPC, so the test uses `dumb_sync_blocks` to submit blocks from the ancient node to the modern node before migrating the wallet.
Each scenario uses its own dedicated old/new node pair, which keeps the setup isolated and makes this testing best managed in a separate file rather than in the existing migration test files.
On the Windows cross-built CI job, this test is excluded from the main functional test runner and re-run sequentially in an ASCII-only tmpdir, because the v0.14.3 binary cannot handle non-ASCII characters in the temporary directory path.

Run `dumpbin.exe /imports` on the cross-built `bitcoind.exe` in the
"Windows, test cross-built" jobs to list the imported DLLs and to
ensure the executable is linked against the expected C runtime.
Test migratewallet on v0.14.3 non-HD and single-chain HD wallets in both
unencrypted and encrypted configurations.
Verify balances, transaction history, address ownership, descriptor
structure, encryption enforcement, backup creation, and the absence of
rescans or unexpected auxiliary wallets.
Run the test with an ASCII-only temporary directory in the Windows
cross-build job because the v0.14.3 binary cannot handle the Unicode
runner path.
The GHA workflows override `BASE_BUILD_DIR`, so the build tree no longer
lives under `BASE_SCRATCH_DIR` and its word-splitting and UTF-8 coverage
is bypassed on CI. Restore it by putting a space and a non-ASCII symbol
in the externally defined path as well.

Pull request description:
This policy, adapted from ripgrep, f0cec341ab/AI_POLICY.md who in turn adapted it from uv c5187e200d/AI_POLICY.md, works as a reasonable and pragmatic AI contribution policy at this point in time.
It codifies roughly how the project is currently operating, it's expectations when Ai is being used, and what we don't wish to see.

This adds a CI job for building the static consensus library and linking it to an executable. It uses newlib-cygwin as a C library for the final linking step. This ensure compatibility with this target going forward and can serve as a starting point for enabling bare metal builds for the entire kernel library. This would have also caught the error fixed in #31365.

726e196ef2 ci: inline runner selection (will)
Pull request description:
We are currently sometimes backlogged on waiting for runner selection.
Selecting Warp or GitHub-hosted runners directly from the repository context avoids serializing all CI jobs behind a metadata job. This keeps forks on public runners while allowing upstream jobs to schedule immediately on the intended runner labels.
This will make the changes needed for "a fork also wanting to use warp runners" slightly larger, but I think that number of people is zero.

Speeds of 1MB/s and 15 minute cached docker image pulls during builds
are not uncommon.
Warp runners provide a local GitHub Actions cache protocol proxy for
Docker layer cache traffic. Point BuildKit's gha cache backend at that
proxy on Warp runners so cached image layers do not have to be fetched
from GitHub's slower cache service.
Add a default for provider so other users (e.g. qa-assets) don't have to
update this unless they use custome runners.
We are currently sometimes backlogged on waiting for runner selection.
Selecting Warp or GitHub-hosted runners directly from the repository context avoids serializing all CI jobs behind a metadata job. This keeps forks on public runners while allowing upstream jobs to schedule immediately on the intended runner labels.
The GHA cache is very slow, taking on the order of minutes to save and
restore from.
Use WarpBuild's cache instead as this is in the same region and much
faster.
WarpBuild cache action does not auto-fallback to GHA if not being run on
Warp. To allow fork runs to fallback to GHA caching, whilst minimising
duplication in the action files, create new "interal" actions which
perform the switching logic, and use these in the (renamed) cache|save
actions.
Without this we would need the `if` logic in our prvious actions, 4
times in each of save and restore.
Plumb the provider through into the action, as a composite action can't
read `env` (`GITHUB_OUTPUT`) from previous steps.

Pull request description:
Part of the effort to remove the libevent dependency altogether, see #31194
This takes the parsing logic from the [`HTTPHeaders` class](d549f01caa) from #32061 and puts it into `bitcoin-cli` as a small `HTTPResponseHeaders` class with a comment to revisit potentially sharing this code somehow. This decoupled the two pulls which seems like the most sensible way to deal with this since the actual overlap is very small compared to the impact of each of the pulls which should ideally not block each other.
Otherwise the change itself replaces the libevent-based HTTP client with a simple synchronous implementation which uses the `Sock` class directly.

Cirrus is winding down and github now offers more than 10GB cache.
Switch to GH cache for all runner-types. Simplify docker build arg
construction, and reduce the number of needed action permissions.
When bigger changes are split across multiple commits, intermediate
commits may introduce unused functions. Do not check for this error
in intermediate commits.
The new cache is keyed with the hash of 'vcpkg.json', which reduces
cache storage consumption compared to keying by run ID.
The `vcpkg/downloads/tools` subdirectory is excluded to further save
space.
Using a non-default target triplet introduced a regression because
packages with `"host": true` in their vcpkg configurations were still
picking up the default `x64-windows` triplet, effectively building both
release and debug packages.
Fix this regression by setting `VCPKG_HOST_TRIPLET` explicitly.

The GHA Windows image contains two vcpkg installations: one vendored by
VS (`VCPKG_ROOT`) and an independent one (`VCPKG_INSTALLATION_ROOT`).
Our build documentation recommends using the VS-vendored instance to
minimize user effort. While this option previously failed to build in
the CI, forcing us to use the independent installation, it is now
working correctly.
This change removes the no-longer-needed workaround.

Makes the functional test compatible with *Linux->Windows cross-built executables*.
Main parts:
* Commit "qa: Check for platform-independent part of error message" switches to match on platform-independent part of error message.
* Commit "qa: Test scanning errors individually" disentangles code causing the same error message substring, based on #31410.
* Commit "qa: Disable parts of the test when running under Windows or root" enables the test to be run on Windows, based in part on https://github.com/bitcoin/bitcoin/pull/31410#issuecomment-3554721014.
Also:
* Removes unused option in wallet_multiwallet.py.
* Breaks apart wallet_multiwallet.py's `run_test()` into smaller test functions.
* Improves `assert_equal()` output for dicts.
Fixes#31409.
