hardcoded nChainTx 91d93aac4e3fe6fff5ef492ed152c4d8fa6f2672 validation: remove nchaintx from assumeutxo metadata (James O'Beirne) 931684b24a89aba884cb18c13fa67ccca339ee8c validation: fix ActivateSnapshot to use hardcoded nChainTx (James O'Beirne) Pull request description: This fixes an oversight from the move of nChainTx from the user-supplied snapshot metadata into the hardcoded assumeutxo chainparams. Since the nChainTx is now unused in the metadata, it should be removed in a future commit.

The first commit is taken from #21781 with the rationale: * In CSignatureCache::ComputeEntryECDSA, change the way a vector pointer is resolved to prevent invoking undefined behavior if the vector is empty. The other commits aim to remove all `&foo[0]`, where `foo` is any kind of byte representation. The rationale: * Sometimes alternative code without any raw data pointers is easier to read (refer to the respective commit message for details) * If the raw data pointer is needed, `foo.data()` should be preferred, as pointed out in the developer notes. This addresses the instances that have been missed in commit 592404f03f2b734351d734f0c9ca1fdce997321b, and https://github.com/bitcoin/bitcoin/pull/9804 ACKs for top commit: laanwj: Code review ACK fac30eec42c486ec1bfd696293040a7aa0f04625 practicalswift: cr ACK fac30eec42c486ec1bfd696293040a7aa0f04625: patch looks correct promag: Code review ACK fac30eec42c486ec1bfd696293040a7aa0f04625.

As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step. Features summary: - Users can start their node with the option `-coinstatsindex` which syncs the index in the background - After the index is synced the user can use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index - The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height ACKs for top commit: Sjors: re-tACK 5f96d7d22d8e05876c6fc014e70488699950fe38 jonatack: Code review re-ACK 5f96d7d22d8e05876c6fc014e70488699950fe38 per `git range-diff 13d27b4 07201d3 5f96d7d` promag: Tested ACK 5f96d7d22d8e05876c6fc014e70488699950fe38.

2021-04-28script: match multisigs with up to MAX_PUBKEYS_PER_MULTISIG keysAntoine Poinsot
We were previously ruling out 17-20 pubkeys multisig, while they are only invalid under P2SH context. This makes multisigs with up to 20 keys be detected as valid by the solver. This is however *not* a policy change as it would only apply to bare multisigs, which are already limited to 3 pubkeys. Note that this does not change the sigOpCount calculation (as it would break consensus). Therefore 1-16 keys multisigs are counted as 1-16 sigops and 17-20 keys multisigs are counted as 20 sigops.

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) ACKs for top commit: fjahr: re-ACK 84934bf70e11fe4cda1cfda60113a54895d4fdd5 ariard: ACK 84934bf.

However, keep a declaration in validation to make it possible to move smaller chunks to blockstorage without breaking compilation. Also, expose AbortNode in the header. Can be reviewed with --color-moved=dimmed-zebra --color-moved-ws=ignore-all-space
