Pull request description:

  This PR makes a number of improvements to the InvalidateBlock (`invalidateblock` RPC) and RewindBlockIndex functions, primarily around breaking up their long-term cs_main holding. In addition:
  * They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again)
  * The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289).
  * `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization).

  This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks.

  I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

Pull request description:

  This change removes wallet calls to node functions that access global chain and mempool state.

  This is the next step in the larger #10973 refactoring change, which removes all other accesses to node global variables from wallet code. Doing this is useful to provide a better defined interface between the wallet and node, and necessary to allow wallet and node code to run in separate processes in #10102.

fa9b60c842 Remove unused TransactionError constants (MarcoFalke)

Pull request description:

  Fixup to #14978, which introduced a bunch of unused enum values, such as `UNKNOWN_ERROR`, `ERROR_COUNT` and `TRANSACTION_ERR_LAST`. None of those have a meaning in the context of an `enum class`, where the compiler can infer if all cases have been covered in a switch-case.

  Also, move the global `::maxTxFee` back to the rpc caller, so it can be set on a per call basis (in the future).

b52cb63688 Add getdescriptorinfo to compute checksum (Pieter Wuille)
3b40bff988 Descriptor checksum (Pieter Wuille)

Pull request description:

  This adds support for a descriptor-specific 8-character checksum.

  Descriptors may optionally be suffixed with a `#` plus these 8 checksum characters. Any descriptor that contains a `#` at the end must be followed by a valid checksum. If the `#` is missing entirely, it is valid without checksum.

  All RPCs are updated to report descriptors that include the checksum. On input, they are optional except in `deriveaddress` and `importmulti`, which require descriptors which include a checksum.

  A new RPC is also added to analyse descriptors (`getdescriptorinfo`), which can be used to compute the checksum for a descriptor without.

7344a7b998 Implement utxoupdatepsbt RPC and tests (Andrew Chow)

Pull request description:

  This PR adds 3 new utility RPCs for interacting with PSBTs.

  `utxoupdatepsbt` updates a PSBT with UTXO information from the node. It only works with witness UTXOs because full transactions (as would be needed for non-witness UTXOs) are not available unless txindex is enabled.

  `joinpsbts` joins the inputs from multiple distinct PSBTs into one PSBT. e.g. if PSBT 1 has inputs 1 and 2, and PSBT 2 has inputs 3 and 4, `joinpsbts` would create a new PSBT with inputs 1, 2, 3, and 4.

  `analyzepsbt` analyzes a PSBT and determines the current state of it and all of its inputs, and the next step that needs to be done.

Pull request description:

  This PR allows for key origin data as defined by the descriptors document to be imported to the wallet when importing a descriptor using `importmulti`. This allows the `walletprocesspsbt` to include the BIP 32 derivation paths for keys that it is watching that are from a different HD wallet.

  In order to make this easier to use, a new field `hdmasterkeyfingerprint` has been added to `getaddressinfo`. Additionally I have removed `hdmasterkeyid` as was planned. I think that this API change is fine since it was going to be removed in 0.18 anyways. `CKeyMetadata` has also been extended to store key origin info to facilitate this.

After refactoring general-purpose PSBT and transaction code out of RPC code,

We still use JSONRPCError() for the error objects, since only RPC callers

PartiallySignedTransaction, into two functions: DecodeBase64PSBT, which retains
the old behavior, and DecodeRawPSBT, which only performs the deserialization.

Add a test for base64 decoding failure.

Pull request description:

  Util is a better home since it's called both by wallet and mining code.

Merge #15226: Allow creating blank (empty) wallets (alternative)
7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)

Pull request description:

  Alternative (kind of) to #14938

  This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.

  Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.

  Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".

  This is built on top of #15225 in order to fix GUI issues.

Andrew Chow 7687f7873b [wallet] Support creating a blank wallet
A blank wallet is a wallet that has no keys, script or watch only things.
A new wallet flag indicating that it is blank will be set when the wallet
is blank. Once it is no longer blank (a seed has been generated, keys or
scripts imported, etc), the flag will be unset.
