faebf62714 rpc: Use Join helper in rpc/util (MarcoFalke)
fa8cd6f9c1 util: Add Join helper to join a list of strings (MarcoFalke)
Pull request description:
We have a lot of enumerations in the code and sometimes those enumerations need to be mentioned in the RPC or command line documentation. Previously, each caller would have a couple of lines inline to join the strings or the joined string is hardcoded in the documentation. A helper to join strings would make code such as https://github.com/bitcoin/bitcoin/pull/16629#discussion_r315852446 less verbose and easier to read.
Also, warnings commonly accumulate in complex RPCs, since a warning doesn't lead to an early return. A helper to join those warnings would make code such as https://github.com/bitcoin/bitcoin/pull/16394/files#r309324997 less verbose and easier to read.

Some failure conditions implicitly fail by failing some other check.
But the error messages are more helpful if they say explicitly what
actually caused the failure, so add those as failure conditions and
errors.

This hardcodes CSV and segwit activation heights, similar to the BIP 90 buried deployments for BIPs 34, 65 and 66.
CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt.

This change encapsulates UTXO set data within CChainState instances, removing
global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to
maintain multiple chainstates with their own rendering of the UTXO set.
We introduce a class CoinsViews which consolidates the construction of a
CCoins* hierarchy. Construction of its various pieces (db, coinscatcher,
in-memory cache) is split up so that we avoid flushing bad state to disk if
startup is interrupted.
We also introduce `CChainState::CanFlushToDisk()` which tells us when it is
safe to flush the chainstate based on this partial construction.
This commit could be broken into smaller pieces, but it would require more
ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor
invocations.
Other changes:
- A parameter has been added to the CCoinsViewDB constructor that allows the
name of the corresponding leveldb directory to be specified.
Thanks to Russell Yanofsky and Marco Falke for helpful feedback.

Pull request description:
# Motivation
In 0.19, bloom filter will be disabled by default. I tried to make [a PR](https://github.com/bitcoin/bitcoin/pull/16176) to enable bloom filter for whitelisted peers regardless of `-peerbloomfilters`.
Bloom filter have non existent privacy and server can omit filter's matches. However, both problems are completely irrelevant when you connect to your own node. If you connect to your own node, bloom filters are the most bandwidth efficient way to synchronize your light client without the need of some middleware like Electrum.
It is also a superior alternative to BIP157 as it does not require to maintain an additional index and it would work well on pruned nodes.
When I attempted to allow bloom filters for whitelisted peer, my proposal has been NACKed in favor of [a more flexible approach](https://github.com/bitcoin/bitcoin/pull/16176#issuecomment-500762907) which should allow node operator to set fine grained permissions instead of a global `whitelisted` attribute.
Doing so will also make follow up idea very easy to implement in a backward compatible way.
# Implementation details
The PR propose a new format for `--white{list,bind}`. I added a way to specify permissions granted to inbound connection matching `white{list,bind}`.
The following permissions exists:
* ForceRelay
* Relay
* NoBan
* BloomFilter
* Mempool
Example:
* `-whitelist=bloomfilter@127.0.0.1/32`.
* `-whitebind=bloomfilter,relay,noban@127.0.0.1:10020`.
If no permissions are specified, `NoBan | Mempool` is assumed. (making this PR backward compatible)
When we receive an inbound connection, we calculate the effective permissions for this peer by fetching the permissions granted from `whitelist` and add to it the permissions granted from `whitebind`.
To keep backward compatibility, if no permissions are specified in `white{list,bind}` (e.g. `--whitelist=127.0.0.1`) then parameters `-whitelistforcerelay` and `-whiterelay` will add the permissions `ForceRelay` and `Relay` to the inbound node.
`-whitelistforcerelay` and `-whiterelay` are ignored if the permissions flags are explicitly set in `white{bind,list}`.
# Follow up idea
Based on this PR, other changes become quite easy to code in a trivially review-able, backward compatible way:
* Changing `connect` at rpc and config file level to understand the permissions flags.
* Changing the permissions of a peer at RPC level.

This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal
---
Under an assumeutxo model, we have multiple CChainState instances in use at once in order to support background validation. 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.

Pull request description:
This PR compresses the `CWallet` chain of inheritance from 5 classes to 3 classes. `CBasicKeyStore` is renamed to `FillableSigningProvider` and some parts of it (the watchonly parts) are moved into `CWallet`. `CKeyStore` and `CCrypoKeyStore` are completely removed. `CKeyStore`'s `Have*` functions are moved into `SigningProvider` and the `Add*` moved into `FillableSigningProvider`, thus allowing it to go away entirely. `CCryptoKeyStore`'s functionality is moved into `CWallet`. 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`).
Implements the 2nd [prerequisite](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#cwallet-subclass-stack) from the wallet restructure.

Pull request description:
Every single RPC call has a helper-section at the start, which throws a help string if the user asks for help or if the user provided too few/many arguments.
```C++
const RPCHelpMan help{...};
if (request.fHelp || !help.IsValidNumArgs(request.params.size())) {
throw std::runtime_error(help.ToString());
}
```
or (older version)
```C++
if (request.fHelp || request.params.size() < min || request.params.size() > max)
throw std::runtime_error(
RPCHelpMan{...}.ToString()
);
```
It seems like an obvious improvement, and less copy-pasting, to make `RPCHelpMan` aware of `JSONRPCRequest`, and to let it handle the checks instead. 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`).

26fe9b9909 Add support for descriptors to utxoupdatepsbt (Pieter Wuille)
3135c1a2d2 Abstract out UpdatePSBTOutput from FillPSBT (Pieter Wuille)
fb90ec3c33 Abstract out EvalDescriptorStringOrObject from scantxoutset (Pieter Wuille)
eaf4f88734 Abstract out IsSegWitOutput from utxoupdatepsbt (Pieter Wuille)
Pull request description:
This adds a descriptors argument to the `utxoupdatepsbt` RPC. This means:
* Input and output scripts and keys will be filled in when known.
* P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they're spending segwit outputs.
This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).

utACK fa2b083c3f [EDIT: was ~e284e422e75189794e24fe482819d8b1407857c3~, from bad copy and paste]. Changes since last review: rebase after #15976, adding vTxHashes lock annotation, adding new commit dropping mempool lock for nTransactionsUpdated and making it atomic to avoid deadlock between mempool lock and g_best_block_mutex
