Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

d831e711ca [validation] RewindBlockIndex no longer needed (Dhruv Mehta)
Pull request description:
Closes#17862
Context from [original comment](https://github.com/bitcoin/bitcoin/issues/17862#issuecomment-744285188) (minor edits):
`RewindBlockIndex()` is a mechanism to allow nodes to be upgraded after segwit activation, while still keeping their chainstate/datadir in a consistent state. It works as follows:
- A pre-segwit (i.e. v0.13.0 or older) node is running.
- Segwit activates. The pre-segwit node remains sync'ed to the tip, but is not enforcing the new segwit rules.
- The user upgrades the node to a segwit-aware version (v0.13.1 or newer).
- On startup, in `AppInitMain()`, `RewindBlockIndex()` is called. This walks the chain backwards from the tip, disconnecting and erasing blocks that from after segwit activation that weren't validated with segwit rules.
- those blocks are then redownloaded (with witness data) and validated with segwit rules.
This logic probably isn't required any more since:
- Segwit activated at height 481824, when the block chain was 130GB and the total number of txs was 250 million. Today, we're at height 667704, the blockchain is over 315GB and the total number of txs is over 600 million. Even if 20% of that added data is witness data (a high estimate), then around 150GB of transactions would need to be rewound to get back to segwit activation height. It'd probably be faster to simply validate from genesis, especially since we won't be validating any scripts before the assumevalid block. It's also unclear whether rewinding 150GB of transactions would even work. It's certainly never been tested.
- Bitcoin Core v0.13 is hardly used any more. https://luke.dashjr.org/programs/bitcoin/files/charts/software.html shows less than 50 nodes running it. The software was EOL on Aug 1st 2018. It's very unlikely that anyone is running 0.13 and will want to upgrade to 0.22.
This PR introduces `NeedsRedownload()` which merely checks for insufficiently validated segwit blocks and requests that the user restarts the node with `-reindex`. Reindexing the block files upon restart will make the node rebuild chain state and block index from the `blk*.dat` files on disk. The node won't be able to index the blocks with `BLOCK_OPT_WITNESS`, so they will be missing from the chain and be re-downloaded, with witness data.
Removing this code allows the following (done in follow-up #21090):
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

The initial refactors and some of the new tests were taken from Amiti Uttarwar's PR #21528 - they are general test improvements not directly tied to the change proposed there.

ce994e1202 test: add tx modfication helper function in feature_cltv.py (Sebastian Falbesoner)
Pull request description:
The functional test for [BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) / `OP_CHECKLOCKTIMEVERIFY` (`feature_cltv.py`) currently only tests one out of five conditions that lead to failure of the op-code -- by prepending the script `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to a tx's first input's scriptSig, the case of "_the top item on the stack is less than 0_" is checked:
f8462a6d27/test/functional/feature_cltv.py (L26-L35)
This PR adds the other cases (5 in total) by taking an integer argument to the function `cltv_invalidate` that is called in a loop instead of only once per testing scenario. Here is the full list of failure conditions and how they are tested (note that the scriptSig should still be valid before activation of BIP65, when `OP_CLTV` is simply a no-op):
* _the stack is empty_
➡️ prepending `OP_CHECKLOCKTIMEVERIFY` to scriptSig
* _the top item on the stack is less than 0_
➡️ prepending `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
* _the lock-time type (height vs. timestamp) of the top stack item and the nLockTime field are not the same_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=1296688602 (genesis block timestamp)
* _the top stack item is greater than the transaction's nLockTime field_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=500
* _the nSequence field of the txin is 0xffffffff_
➡️ prepending `OPNum(500) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0xffffffff and tx.nCheckTimeLock=500
The first commit creates a helper function for the tx modification and also includes some tidying up like turning single-line to multi-line Python imports where necessary and cleaning up some PEP8 warnings. The second commit prepares the invalidation function `cltv_invalidate` and the third and the fourth use it and check for the expected reject reason strings ("Operation not valid with the current stack size", "Negative locktime" and "Locktime requirement not satisfied").

Pull request description:
This picks up the closed pull request #21030 and is the first step toward fixing #21220.
The basic idea is to move all disk access into a separate module with benefits:
* Breaking down the massive files init.cpp and validation.cpp into logical units
* Creating a standalone-module to reduce the mental complexity
* Pave the way to fix validation related circular dependencies
* Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

This commit moves the ExternalSigner class and RPC methods out of the wallet module.
The enumeratesigners RPC can be used without a wallet since #21417.
With additional modifications external signers could be used without a wallet in general, e.g. via signrawtransaction.
The signerdisplayaddress RPC is ranamed to walletdisplayaddress because it requires wallet context.
A future displayaddress RPC call without wallet context could take a descriptor argument.
This commit fixes a rpc_help.py failure when configured with --disable-wallet.

While here, also improve the `getnodeaddresses` code and help.

Pull request description:
Previously SignatureExtractorChecker took a MutableTransactionSignatureChecker and passed through function calls to that. However not all functions were implemented so not everything passed through as it should have. To solve this, SignatureExctractorChecker now implements all of those functions via a new class - DeferredSignatureChecker. DeferredSignatureChecker is introduced to allow for future signature checkers which use another SignatureChecker but need to be able to do somethings outside of just the signature checking.
