(Matt Corallo) Pull request description: BIP 37 bloom filters have been well-known to be a significant DoS target for some time. However, in order to provide continuity for SPV clients relying on it, the NODE_BLOOM service flag was added, and left as a default, to ensure sufficient nodes exist with such a flag. NODE_BLOOM is, at this point, well-established and, as long as there exist 0.18 nodes with default config (which I'd anticipate will be true for many years), will be available from some peers. By that time, the continued slowdown of BIP 37-based filtering will likely have rendered it useless (though this is already largely the case). Further, BIP 37 was deliberately never updated to support witness-based filtering as newer wallets are expected to migrate to some yet-to-be-network-exposed filters.

Implementers such as myself may fail to complete this pattern, and could result in key re-use: https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393 Since ReserveDestination is currently only used directly in the `CreateTransaction`/`CommitTransaction` flow(or fee bumping where it's just used in `CreateTransaction`), I instead make the assumption that if a transaction is returned by `CreateTransaction` it's highly likely that it will be accepted by the caller, and the `ReserveDestination` kept. This simplifies the API as well. There are very few cases where this would not be the case which may result in keys being burned. Those failure cases appear to be: `CommitTransaction` failing to get the transaction into the mempool Belt and suspenders check in `WalletModel::prepareTransaction` Alternative to https://github.com/bitcoin/bitcoin/pull/15796 ACKs for top commit: achow101: ACK e10e1e8db043e9b7c113e07faf408f337c1b732d Reviewed the diff stevenroose: utACK e10e1e8db043e9b7c113e07faf408f337c1b732d meshcollider: utACK e10e1e8db043e9b7c113e07faf408f337c1b732d Tree-SHA512: 78d047a00f39ab41cfa297052cc1e9c224d5f47d3d2299face650d71827635de077ac33fb4ab9f7dc6fc5a27f4a68415a1bc9ca33a3cb09a78f4f15b2a48411b

Currently, each CChainState instance has its own mapBlockIndex, a collection of linked block headers, in addition to a few other data structures that are related to maintenance of the block tree but not necessarily to any given chainstate. In order to avoid duplicating this data across chainstates, this change moves chainstate-agnostic block metadata (and related behavior) into a class, `BlockManager`. Chainstates are parameterized with a reference to a blockmanager instance and in practice they share the same instance. Most of this change is conceptually move-only, though the diff is somewhat muddled. The first commit can be reviewed slightly more easily with `--color-moved=dimmed_zebra`. Admittedly, that commit is pretty unwieldy; I tried to split it up after the fact with `git add --patch`, but that was difficult because of git's inability to split hunks past a certain point. Some of the moves also ended up being obscured when done over separate commits.

The new inheritance chain is: ``` SigningProvider -> FillableSigningProvider -> CWallet ``` `SigningProvider` now is the class the provides keys and scripts and indicates whether keys and scripts are present. `FillableSigningProvider` allows keys and scripts to be added to the signing provider via `Add*` functions. `CWallet` handles all of the watchonly stuff (`AddWatchOnly`, `HaveWatchOnly`, `RemoveWatchOnly` which were previously in `CKeyStore`) and key encryption (previously in `CCryptoKeyStore`).

It should be the one that handles the conversion from key to destination and the setting of the label, not the caller. In order to do this, two new member functions are introduced `GetNewDestination()` and `GetNewChangeDestination()`. Additionally, `CReserveKey` is changed to be `ReserveDestination` and represents destinations whose keys can be returned to the keypool.

Both of the above become ```C++ RPCHelpMan{...}.Check(request); ``` which means we save roughly 3 lines per RPC command, and the `RPCHelpMan` instance is never referenced afterwards, so the approach is a tiny fraction cleaner. This is a complete update, sans a few special case locations that had special rules. 623 lines turn into 284 (which includes the addition to `RPCHelpMan`).
