3b11420b3c [RPC] add new utxoupdatepsbt arguments to the CRPCCommand and CPRCConvertParam tables (John Newbery)
Pull request description:
The new `descriptors` argument was not added to the CRPCCommand and CPRCCvertParam tables, meaning that it couldn't be used with bitcoin-cli or named arguments.

fab0c820fa rpc: Clarify that block count means height excl genesis (MarcoFalke)
Pull request description:
There is a common misconception that the block count returned by the blockchain rpcs includes the genesis block. See for example the discussion in https://github.com/bitcoin/bitcoin/pull/16292#issuecomment-506303256.
However, it really returns the height, which is `0` for the genesis block.
So clarify that and also remove the misleading "longest blockchain" comment.
Finally, fix the wallet test that incorrectly used this rpc.

01174596e6 signrawtransactionwithkey: report error when missing redeemScript/witnessScript param (Anthony Towns)
Pull request description:
Adding support for "witnessScript" as an alternative to "redeemScript" when using "signrawtransactionwithkey" meant that the `RPCTypeCheckObj()` call in `SignTransaction` can't error out just because either parameter is missing -- it's only a problem if both are missing, which isn't a state `RPCTypeCheckObj()` tests for. This results in the regression described in #16249. This patch adds some code to test for this case and give a similar error, namely:
error code: -8

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`).

before that change it was controlled by a condition variable and lock.
a49503402b Make and get the multisig redeemscript and destination in one function instead of two (Andrew Chow)
Pull request description:
`CreateMultisigRedeemscript()` is changed to `AddAndGetMultisigDestination()` so that the process of constructing the redeemScript and then getting the `CTxDestination` are done in the same function. This allows that function to see what the keys in the multisig are so that the correct address type is returned from `AddAndGetDestinationForScript()`.
This only effects the `createmultisig` and `addmultisigaddress` RPCs and does not change signing logic as #16022 does.
Alternative to #16022 and #16012Fixes#16011

Instead of creating a redeemScript with CreateMultisigRedeemscript and
then getting the destination with AddAndGetDestinationForScript, do
both in the same function.
CreateMultisigRedeemscript is changed to AddAndGetMultisigDestination.
It creates the redeemScript and returns it via an output parameter. Then
it calls AddAndGetDestinationForScript to add the destination to the
keystore and get the proper destination.
This allows us to inspect the public keys in the redeemScript before creating
the destination so that the correct destination is used when uncompressed
pubkeys are in the multisig.

Pull request description:
Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.
This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.
This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.

Pull request description:
Make reasoning about dependencies easier by not including unused dependencies.
Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.
As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:
```
$ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
sed 's%^%src/%g' | xargs cat | wc -l
51393
```
Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)

Pull request description:
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
---
This changeset starts moving functionality intimately related to CChainState into methods. Parameterizing these functions by a particular CChainState is necessary for the use of multiple chainstates simultaneously (e.g. for asynchronous background validation).
In this change, we
- make the CChainState interface public - since other units will start to invoke its methods directly,
- introduce `::ChainstateActive()`, the CChainState equivalent for `::ChainActive()`,
- and move `IsInitialBlockDownload()` and `FlushStateToDisk()` into methods on CChainState.
Independent of assumeutxo, these changes better encapsulate chainstate behavior and allow easier use from a testing context.
There are more methods that we'll move in the future, but they require other substantial changes (i.e. moving ownership of the `CCoinsView*` hierarchy into CChainState) so we'll save them for future PRs.
---
The first move-only commit is most easily reviewed with `git diff ... --color-moved=dimmed_zebra`.

e23809a05b [rpc] deriveaddresses: Correct descriptor checksum in RPCExamples (Chris Capobianco)
Pull request description:
Trvial: This fixes the descriptor checksum found the in the deriveaddresses RPC example.
The current checksum value does work, but only if the "h" used for the hardened derivation key origin are replaced with "'".
Given the discussion to switch from "'" to "h" [here](https://github.com/bitcoin/bitcoin/issues/15740), I thought it made more sense to update the checksum rather then changing all the "h" to "'" in this example.

Also renames global methods for clarity:
- ::FlushStateToDisk() -> CChainState::ForceFlushStateToDisk()
- This performs an unconditional flush.
- ::PruneAndFlush() -> CChainState::PruneAndFlush()
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 outputs will be filled in from the UTXO set when a descriptor
is provided to show they're segwit outputs.
This is not a pure refactor; additional functionality is added in
IsSegWitOutput which lets it recurse into P2SH when a
SigningProvider is provided that knows about the inner script.

78e407ad0c GetKeyBirthTimes should return key ids, not destinations (Gregory Sanders)
70946e7fee Replace CScriptID and CKeyID in CTxDestination with dedicated types (Gregory Sanders)
Pull request description:
The current usage seems to be an overloading of meanings. `CScriptID` is used in the wallet as a lookup key, as well as a destination, and `CKeyID` likewise. Instead, have all destinations be dedicated types.
New types:
`CScriptID`->`ScriptHash`
`CKeyID`->`PKHash`

Though at the moment ChainActive() simply references `g_chainstate.m_chain`,
doing this change now clears the way for multiple chainstate usage and allows
us to script the diff.
