Pull request description:
This PR updates the `test/get_previous_releases.py` script to also work on Windows by changing to be pure python rather than using unix tools such as `curl` and `tar`.
This enables additional functional tests to run such as `wallet_migration.py`, `mempool_compatability.py` and `wallet_backwards_compatibility.py`.
Unfortunately `feature_unsupported_utxo_db.py` _could_ run but this test requires Bitcoin `v0.14.3` which will not run under windows with emojis in the data directory (as the functional test runner has by default) . This test could be run as it's own step in the ci workflow file and would pass but as it's quite an old version / feature I have assumed it's not worth worrying about and best just to exclude.
Two tests needed to be slightly modified to run under windows. Both were issues with trying to overwrite a file that already exists which windows seems to be more strict on than the unix based systems.
Finally, building from source has been dropped from the `get_previous_releases.py` script. This had not been updated after the move to cmake and so it was assumed that nobody could have been using that feature.

e02f2d331ce6d9c5b6b8f62a79dd40695d2283a2 bench: Have AvailableCoins benchmark include a lot of unrelated utxos (Ava Chow)
Pull request description:
Currently, the wallet is not actually aware about its own transaction outputs. Instead, it will iterate all of the transactions stored in `mapWallet`, and then all of the outputs of those transactions, in order to figure out what belongs to it for the purposes of coin selection and balance calculation. For balance calculation, there is caching that results in it only iterating all of the transactions, but not all of the outputs. However when the cache is dirty, everything is iterated. This is especially problematic for wallets that have a lot of transactions, or transactions that have a lot of unrelated outputs (as may occur with coinjoins or batched payments).
This PR helps to resolve this issue by making the wallet track all of the outputs that belong to it in a new member `m_txos`. Note that this includes outputs that may have already been spent. Both balance calculation (`GetBalance`) and coin selection (`AvailableCoins`) are updated to iterate `m_txos`. This is generally faster since it ignores all of the unrelated outputs, and it is not slower as in the worst case of wallets containing only single output transactions, it's exactly the same number of outputs iterated.
`m_txos` is memory only, and it is populated during wallet loading. When each transaction is loaded, all of its outputs are checked to see if it is `IsMine`, and if so, an entry added to `m_txos`. When new transactions are received, the same procedure is done.
Since imports can change the `IsMine` status of a transaction (although they can only be "promoted" from watchonly to spendable), all of the import RPCs will be a bit slower as they re-iterate all transactions and all outputs to update `m_txos`.
Each output in `m_txos` is stored in a new `WalletTXO` class. This class contains references to the parent `CWalletTx` and the `CTxOut` itself. It also caches the `IsMine` value of the txout. This should be safe as `IsMine` should not change unless there are imports. This allows us to have additional performance improvements in places that use these `WalletTXO`s as they can use the cached `IsMine` rather than repeatedly calling `IsMine` which can be expensive.
The existing `WalletBalance` benchmark demonstrates the performance improvement that this PR makes. The existing `WalletAvailableCoins` benchmark doesn't as all of the outputs used in that benchmark belong to the test wallet. I've updated that benchmark to have a bunch of unrelated outputs in each transaction so that the difference is demonstrated.
This is part of a larger project to have the wallet actually track and store a set of its UTXOs.
Built on #24914 as it requires loading the txs last in order for `m_txos` to be built correctly.

Pull request description:
The `test/util/test_runner.py` has many issues:
* The boilerplate for the test runner is duplicate or inconsistent with the other (functional) tests. For example, logging options, `ConfigParser` handling, `Binaries` handling ...
* The cmake/ci behavior is brittle and can silently fail, as explained in https://github.com/bitcoin/bitcoin/issues/31476
* corecheck (and likely other places that manually run the tests) completely forget to run it
* If the test is manually called, it runs single threaded, when it could just run in parallel with the other functional tests
Fix all issues by removing the util test_runner and moving the test logic into a new functional test file.

d4e212e8a69ea118acb6caa1a7efe64a77bdfdd2 rest: fetch spent transaction outputs by blockhash (Roman Zeyde)
Pull request description:
Today, it is possible to fetch a block's spent prevouts in order to build an external index by using the `/rest/block/BLOCKHASH.json` endpoint. However, its performance is low due to JSON serialization overhead.
We can significantly optimize it by adding a new [REST API](https://github.com/bitcoin/bitcoin/blob/master/doc/REST-interface.md) endpoint, using a binary response format (returning a collection of spent txout lists, one per each block transaction):
```
$ BLOCKHASH=00000000000000000002a7c4c1e48d76c5a37902165a270156b7a8d72728a054

dd8447f70faf6419b4617da3c1b57098e9cd66a6 test: fix catchup loop in outbound eviction functional test (Sebastian Falbesoner)
Pull request description:
In the course of working on an equivalent of #32421 for the `CBlockHeader` class, I noticed that the [catchup loop in the outbound eviction functional test](19765dca19/test/functional/p2p_outbound_eviction.py (L86-L103)) currently has a small flaw: the contained waiting for a `getheaders` message
19765dca19/test/functional/p2p_outbound_eviction.py (L98-L99)
only waits for _any_ such message instead of one with the intended block hash after the first iteration. The reason is that the `prev_prev_hash` variable is set incorrectly, since the `tip_header` instance is not updated and its field `.hash` is None [1]. Fix that by updating `tip_header` after generating a new block and also use the correct field on it -- we want the tip header's previous hash (`.hashPrevBlock`), which will be the previous-previous hash in the next iteration as intended.
Can be demonstrated by adding a debug output for `prev_prev_hash`, e.g.
```diff

[1] that's in my opinion another example how caching hashes is confusing and easy to be misused; it's better to remove it and just compute the hash on-the-fly, so returning None is not even possible anymore

Pull request description:
`getwalletinfo` result fields `balance`, `immature_balance`, and `unconfirmed_balance`, and the `getunconfirmedbalance` RPC have all been deprecated since 0.19.0. It's been long enough that they should either be removed or undeprecated. The functionality provided by these RPCs is provided by `getbalances`.

The wallet backups performed before migration use the time as part of
their filename. As the time is mocked, increment it between migration
attempts to prevent file name conflicts which is a problem on Windows.
Using the get_previous_releases.py script to build from source only works for
releases prior to v29 due to removal of Autotools (in favor of CMake). It also
does not support building on Windows, and we are adding support for downloading
Windows release binaries in later commits of this PR.
As there were no complaints during review, it is assumed nobody uses this
functionality.

Pull request description:
Fixes [#32334](https://github.com/bitcoin/bitcoin/issues/32334)
The test `feature_bip68_sequence.py` fails with `IndexError: list index out of range` error due to a mismatch between the number of inputs requested (at random) and the number of UTXOs available. The error is reproducible with the randomseed:
```
$ ./build/test/functional/feature_bip68_sequence.py --randomseed 6169832640268785903

Pull request description:
This PR adds the IPC equivalent of the `getblocktemplate` RPC in `proposal` mode.
In order to do so it has `TestBlockValidity` return error reasons as a string instead of `BlockValidationState`. This avoids complexity in IPC code for handling the latter struct.
The new Mining interface method is used in `miner_tests`.
It's not used by the `getblocktemplate` and `generateblock` RPC calls, see https://github.com/bitcoin/bitcoin/pull/31981#discussion_r2096473337
The `inconclusive-not-best-prevblk` check is moved from RPC
code to `TestBlockValidity`.
Test coverage is increased by `mining_template_verification.py`.
Superseedes #31564
## Background
### Verifying block templates (no PoW)
Stratum v2 allows miners to generate their own block template. Pools may wish (or need) to verify these templates. This typically involves comparing mempools, asking miners to providing missing transactions and then reconstructing the proposed block.[^0] This is not sufficient to ensure a proposed block is actually valid. In some schemes miners could take advantage of incomplete validation[^1].
The Stratum Reference Implementation (SRI), currently the only Stratum v2 implementation, collects all missing mempool transactions, but does not yet fully verify the block.[^2]. It could use the `getblocktemplate` RPC in `proposal` mode, but using IPC is more performant, as it avoids serialising up to 4 MB of transaction data as JSON.
(although SRI could use this PR, the Template Provider role doesn't need it, so this is _not_ part of #31098)

Pull request description:
When attempting to sign a transaction involving an external signer, if the device isn't connected we throw an `std::runtime_error`. This prevents the (mainly GUI) code that's actually supposed to handle this case from running.
This PR returns a `PSBTError::EXTERNAL_SIGNER_NOT_FOUND` instead of throwing.
The first commit is a refactor to have `GetExternalSigner()` return a `util::Result<ExternalSigner>` so the caller can decide how to handle the error. There are two other places where call `GetExternalSigner()` which this PR doesn't change (which I think is fine there).

The catchup loop in the outbound eviction functional test currently has
a small flaw, as the contained waiting for a `getheaders` message just
waits for any such message instead of one with the intended block hash.
The reason is that the `prev_prev_hash` variable is set incorrectly,
since the `tip_header` instance is not updated and its field `.hash` is
None. Fix that by updating `tip_header` and use the correct field -- we
want the tip header's previous hash (`.hashPrevBlock`).

a2724e3ea392cdbd5526735516862b17bf687624 test: remove txid caching in CTransaction class (Sebastian Falbesoner)
Pull request description:
In the functional test framework, determining a (w)txid for a `CTransaction` instance is currently rather confusing and footgunny due to inconsistent naming/interfaces (see table below) and statefulness involved. This PR aims to improve that by:
* removing the (w)txid caching mechanism, in order to avoid the need to call additional rehashing functions (`.rehash()`/`.calculate_sha256()`, see first two commits and https://github.com/bitcoin/bitcoin/pull/32050#discussion_r1993286997). This change in theory decreases the performance, as the involved serialization and hashing involved might be called more often than previously, but I couldn't find a functional test where this leads to a measurable run-time increase on my machine.
* introduce consistent naming that shows the type of the returned txid, i.e. hex string vs. test-framework-internal representation [currently integers] (see remaining commits)
Summary table showing (w)txid determaination before/after this PR:
| Task | master | PR |
|:-----------------------|:-----------------------|:-------------|
| get TXID (hex string) | `.rehash()` / `.hash`[1] | `.txid_hex` |
| get TXID (integer) | `.sha256`[1] | `.txid_int` |
| get WTXID (hex string) | `.getwtxid()` | `.wtxid_hex` |
| get WTXID (integer) | `.calc_sha256(True)` | `.wtxid_int` |
Unfortunately, most renames can't be done with a scripted-diff, as the property names (`.hash`, `.sha256`) are also used for blocks and other message types. The PR is rather invasive and touches a lot of files, but I think it's worth to do it, also to make life easier for new contributors. Future tasks like e.g. doing the same overhaul for block (header) objects or getting rid of the integer representation (see https://github.com/bitcoin/bitcoin/pull/32050) become easier should become easier after this one.

Rather than determining a CTransaction's (w)txid as an integer by
converting it's hex value, it can be directly accessed via the
introduced `.{w,}txid_int` property.

f16c8c67bf137e64fbeea1242431baaa915a5c53 tests: Expand HTTP coverage to assert libevent behavior (Matthew Zipkin)
Pull request description:
These commits are cherry-picked from #32061 and part of a project to [remove libevent](https://github.com/bitcoin/bitcoin/issues/31194).
This PR only adds functional tests to `interface_http` to cover some HTTP server behaviors we inherit from libevent, in order to maintain those behaviors when we replace libevent with our own HTTP server.
1. Pipelining: The server must respond to requests from a client in the order in which they were received [RFC 7230 6.3.2](https://www.rfc-editor.org/rfc/rfc7230#section-6.3.2)
2. `-rpcservertimeout` config option which sets the amount of time the server will keep an idle client connection alive
3. "Chunked" Transfer-Encoding: Allows a client to send a request in pieces, without the `Content-Length` header [RFC 7230 4.1](https://www.rfc-editor.org/rfc/rfc7230#section-4.1)
