cbd345a75c test: test OP_CSV empty stack fail in feature_csv_activation.py (Sebastian Falbesoner)
Pull request description:
Adds an empty stack failure check for OP_CSV (BIP112) to the functional test `feature_csv_activation.py` by prepending a valid scriptSig with `OP_CHECKSEQUENCEVERIFY`.
If BIP112 is inactive, the operator just behaves as a NOP (for both tx versions 1 and 2) and the transaction remains valid -- if it is active, the tx is invalid due to an empty stack (for both tx versions 1 and 2, as well).
Top commit has no ACKs.

With BIP112 activated, the operation OP_CHECKSEQUENCEVERIFY (former OP_NOP3)
leads to script interpreter termination with an error if one of the following
conditions is true:
-> stack is empty
-> top item on stack is negative (< 0)
-> top item on stack has disable flag unset and at least one of
four other conditions is true (contains the core CSV logic)
This commits adds the missing empty stack failure test to the functional test
by prepending a valid scriptSig with just OP_CHECKSEQUENCEVERIFY. If BIP112 is
inactive, the operator just behaves as a NOP (for both tx versions 1 and 2) and
the transaction remains valid -- if it is active, the tx is invalid due to an
empty stack (for both tx versions 1 and 2, as well).

b902bd66b0 test: check custom descendant limit in mempool_packages.py (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR to #17435, testing the custom descendant limit, passed by the argument `-limitdescendantcount`. ~~It was more tricky than expected, mainly because we don't know for sure at which point node1 has got all the transactions broadcasted from node0 (for the ancestor test this wasn't a problem since the txs were immediately available through `invalidateblock`) -- a simple `sync_mempools()` doesn't work here since the mempool contents are not equal due to different ancestor/descendant limits. Hence I came up with a "hacky manual sync":~~
1. ~~wait until the mempool has the _expected_ tx count (see conditions below)~~
2. ~~after that, wait some time and get sure that the mempool contents haven't changed in-between~~
~~Like for~~ Similar to the ancestor test, we overall check for ~~three~~ four conditions:
- the # of txs in the node1 mempool is equal to the descendant limit (plus 1 for the parent tx, plus the # txs from the previous ancestor test which are still in) ~~(done by the hacky sync above)~~
- all txs in node1 mempool are a subset of txs in node0 mempool
- part of the constructed descendant-chain (the first ones up to the limit) are contained in node1 mempool
- the remaining part of the constructed descendant-chain (all after the first ones up to the limit) is *not* contained in node1 mempool

be94096dfb Fix a violation of C++ standard rules that unions cannot be switched. (Samer Afach)
Pull request description:
Type punning in C++ is not like C. As per the C++ standard, one cannot use unions to convert the bit type. A discussion about this can be found [here](https://stackoverflow.com/questions/25664848/unions-and-type-punning). In C++, a union is supposed to only hold one type at a time. It's intended to be used only as `std::variant`. Switching types is undefined behavior.
In fact, C++20 has a special casting function, called [`bit_cast`](https://en.cppreference.com/w/cpp/numeric/bit_cast) that solved this problem.
Why has it been working so far? Because some compilers tolerate using unions and switching types, like gcc. More information [here](https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Type-punning).
One important thing to mention is that performance is generally not affected by that memcpy. Compilers are smart enough to convert that to a memory cast when possible. But we have to do it the right way, otherwise, it's jut undefined behavior that depends on the compiler.

facb71576c net: Remove forcerelay of rejected txs (MarcoFalke)
Pull request description:
This removes the code that supposedly handled the forced relay of txs from a permissioned peer that were rejected from our mempool. The removal should be fine, because it is dead code for the following reasons:
* While `RelayTransaction` enqueues the inv for all peers, the inv is never processed because it can not be found in the mempool. See 4a07233076/src/net_processing.cpp (L3862-L3866)
* Even if the peers we intended to send the inv to can somehow reply with a getdata to the never-received inv, they won't receive the tx as a reply because it was never added to the "relay memory" (`mapRelay`)
The dead code is (obviously) untested: https://marcofalke.github.io/btc_cov/total.coverage/src/net_processing.cpp.gcov.html#2574
This feature was (intentionally or accidentally) removed in 4d8993b346, which was released in Bitcoin Core 0.13.0. So all currently supported versions of Bitcoin Core ship without this feature. I am not aware of any complaints about this feature or actual documented use-cases. So instead of reviving an unneeded feature, just remove the dead code.

Pull request description:
In https://github.com/bitcoin/bitcoin/pull/13557#pullrequestreview-135905054 I recommended not including bip32 deriviation by default in PSBTs:
> _Bit of a privacy issue_: let's say person A and B are about to spend from a multisig address, sending everything to person A. Person A gives their address to person B, their wallet wallet creates a PSBT, but doesn't sign it. Wallet A then calls `walletprocesspsbt` which signs it and _spontaneously adds the master_fingerprint and bip32 path_. Same issue with `walletcreatefundedpsbt`.
>
> Adding `bip32_derivs` should probably be opt-in.
In practice I find this default quite annoying because I forget it and end up with a confused hardware wallet.
More importantly, in the multisig example I provided, it's actually essential for the other side to know the derivation details (in addition to an xpub). This allows them to check that change is going to an address you can still co-sign for (because the spending policy is unchanged except for an index).

7e80f646b2 Get the OutputType for a descriptor (Andrew Chow)
Pull request description:
Adds a `GetOutputType()` method to get the OutputType of a descriptor. Some descriptors don't have a determinate OutputType, so we actually use an `Optional<OutputType>`. For descriptors with indeterminate OutputType, we return `nullopt`.
`addr()` and `raw()` use OutputTypes as determined by the CTxDestination they have. For simplicity, `ScriptHash` destinations are `LEGACY` even though they could be `P2SH_SEGWIT`.
`combo()`, `pk()`, and `multi()` are `nullopt` as they either don't have an OutputType or they have multiple. `DescriptorImpl` defaults to `nullopt`.
`pkh()` is `LEGACY` as expected
`wpkh()` and `wsh()` are `BECH32` as expected.
`sh()` checks whether the sub-descriptor is `BECH32`. If so, it is `P2SH_SEGWIT`. Otherwise it is `LEGACY`.
The descriptor tests are updated to check the OutputType too.

d6d2602a32 add: test that transactions expire from mempool (0xb10c)
Pull request description:
This adds the functional test `mempool_expiry.py` covering mempool transaction expiry. Both the default `DEFAULT_MEMPOOL_EXPIRY` of 336 hours (two weeks, set in #9312) and the user definable mempool expiry via the `-mempoolexpiry=<n>` command line option are tested. The test checks that descendants of expired transactions are removed as well.
*Notes for reviewers*
- `LimitMempoolSize()` (which is the only caller of `CTxMemPool::Expire()`) is only called when a transaction is added to the mempool. In order to test expiry of a transaction-that-should-expire, the mocktime is set and a random transaction is broadcast to trigger `LimitMempoolSize()`. The transaction-that-should-expire is then checked for expiry. LMK if there is another way, but I don't think there is.

005f8a92cc wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition (Russell Yanofsky)
Pull request description:
Make `LegacyScriptPubKeyMan::CanProvide` method able to recognize p2sh scripts when the redeem script is present in the `mapScripts` map without the p2sh script also having to be added to the `mapScripts` map. This restores behavior prior to #17261, which I think broke backwards compatibility with old wallet files by no longer treating addresses created by `addmultisigaddress` calls before #17261 as solvable.
The reason why tests didn't fail with the CanProvide implementation in #17261 is because of a workaround added in 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem for new `addmultisigaddress` RPC calls without fixing it for multisig addresses already created in old wallet files.
This change adds a lot of comments and allows reverting commit 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", so the `AddAndGetDestinationForScript()` function, `CanProvide()` method, and `mapScripts` map should all be more comprehensible

a6f63598ad [util] allow scheduler to be mocked (Amiti Uttarwar)
Pull request description:
This PR is to support functional tests by allowing the scheduler to be mocked via the RPC.
It adds a `MockForward` method to the scheduler class that iterates through the task queue and reschedules them to be `delta_seconds` sooner.
This is currently used to support functional testing of the "unbroadcast" set tracking in #18038. If this patch is accepted, it would also be useful to simplify the code in #16698.

530d02addb build: pass -fno-ident in Windows gitian descriptor (fanquake)
Pull request description:
`-fno-ident` prevents compilers from emitting compiler name and version number information that can needlessly bloat binaries.
For example, in the `v0.19.0.1` Windows release binaries, there are > 1000 GCC compiler version strings embedded:
```bash
# GCC: (GNU) 7.3-posix 20180312... & GCC: (GNU) 6.3.0 20170415.......
strings bitcoind.exe | rg GCC | wc -l
1021
```
They end up collected in the end of the`.rdata` section, and cannot be removed by `strip`. i.e:
```bash
objdump --section=.rdata --full-contents bitcoind.exe
