Pull request description:
Compiling master (d8fc9979130a268cf55b12c223b20fd7d4b9f67f) on macOS Catalina (with a patch from #16720) reveals one more instance of `QFontMetrics::width()` which is supposed to be replaced with `TextWidth()` in the merged #16701.
Sorry for incomplete solution provided in #16701. It’s especially sad that the line I missed lies in only 7 lines from the code touched in #16701.

798a589aff64b83a0844688a661f4bd987c3340c wallet: extract PubKey from P2PK script with Solver (Sebastian Falbesoner)
Pull request description:
The function `ExtractPubKey()` checks if a given script matches the P2PK pattern
(`<PubKey> OP_CHECKSIG`), extracts the PubKey and additionally checks if it is
cryptographically valid (full validation with ECC library via `CPubKey::IsFullyValid()`).
Currently this is done manually in the following order:
1. check if first script OP is data push with valid PubKey length (first part of pattern match), extract PubKey
2. create `CPubKey` object with extracted PubKey
3. fully validate public key
4. check if last script OP is `OP_CHECKSIG` (second part of pattern match)
Using Solver, the pattern matching and PubKey extraction can be done via a
single step, leading to the following simplified order with shorter code:
1. check if given script matches P2PK pattern with Solver (also contains valid PubKey length check), extracts Pubkey
2. create `CPubKey` object with extracted Pubkey
3. fully validate public key

fa0b910486e9aada077fe47e1201dcb3bd523c87 [doc] chain: Declare BLOCK_VALID_HEADER reserved (MarcoFalke)
Pull request description:
`BLOCK_VALID_HEADER` was never used and the comment is confusing to me in several ways:
* It claims "version ok". However, without the previous header, it is not possible to check the validity of the version since the height needs to be known (c.f. BIP 90)
* It claims "hash satisfies claimed PoW". While it is possible to check against the claimed PoW, it is not possible without the previous header to check that the claimed PoW is itself valid.
* It claims "1 <= vtx count <= max". However, with the header alone and current consensus rules, the number of transactions is unknown.

Add a LockChain method to CWallet to know if we can lock or query
chain state safely.
At tx loading, we rely on chain to know if hashBlock of tx is still
in main chain. If not, we set its status to unconfirmed and reset
its hashBlock/nIndex.
If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as status is not
used by wallet-tool.
We take lock prematurely in CWallet::LoadWallet and CWallet::Verify
to ensure that lock order is respected between cs_main an cs_wallet.
d48c1e837ae1bd08e0f18ad1b57ff72675c3d6ad Add window final block height to getchaintxstats (Jonathan "Duke" Leto)
Pull request description:
This patch is motivated by the desire to make the output of `getchaintxstats` more useful and optimized for applications to consume and render the data.
Firstly, this data is already available to the RPC, no additional work is done. Currently additional RPC calls will be needed to look up the height of the final block in the window or the block height that began the window.
By adding the block height of the final block in the window, the JSON is "self-contained" and applications can calculate the exact block height range of the window with no additional RPC requests.
For example, a web application which wants to render historical information for `getchaintxstats` RPC on various window sizes might call the RPC with various window lengths, once per day, and store the JSON results somewhere. Because the final block height of each dataset is included, it's no extra work to determine the exact block window range of each JSON response.

Changing the util methods in util/error to return a bilingual_str paves

---
In the short-term, this move-only commit will help with fuzzing (https://github.com/bitcoin/bitcoin/pull/15606#issuecomment-524482297). Later, these procedures will be used to compute statistics (particularly a content hash) for UTXO sets coming in from snapshots.
Most easily reviewed with `git ... --color-moved=dimmed_zebra`. A nice follow-up would be adding unittests, which I'll do if nobody else gets around to it.

These procedures will later be used in the ChainstateManager to compute
statistics (particularly a content hash) for UTXO sets coming in from
snapshots.
We shouldn't rely on this sync call to get an accurate view of txn
state, if a tx conflicts with one in mapTx we are going to update
our wallet dependencies in AddToWalletIfInvolvingMe while conflicting
txn get connected. If it doesn't conflict with one of our dependencies
we are not going to track it anyway.
This is a cleanup, as this SyncTransaction is redundant with the
following one for confirmation which is triggering the MarkConflicted
logic. We keep the loop because set of conflicted txn isn't same as txn
included in block.
Instead of relying on combination of hashBlock and nIndex
values to manage tx in its lifecycle, we introduce 4
status : CONFIRMED, UNCONFIRMED, CONFLICTED, ABANDONED.
hashBlock and nIndex magic values should only be used at
serialization/deserialization for backward-compatibility.
At block disconnection, we know flag txn as UNCONFIRMED where
previously they kept their states until being override by a
block connection or abandontransaction call. This is a change
in behavior for which user may have to call abandon twice
if transaction is disconnected and not accepted back in the mempool.
We assert status transitioning right in AddToWallet. Doing so
flagged a misbehavior in ComputeTimeSmart unit test where same
tx is confirmed twice in different block. To avoid inconsistencies
we unconfirmed tx before new connection in different block. We
also remove a cs_main lock in test, as AddToWallet and its
callees don't rely on locked chain.
In Qt 5.12 and before the QFontMetrics::width() is used and it is
deprecated since Qt 13.0.
In Qt 5.11 the QFontMetrics::horizontalAdvance() was introduced.
If sending to multiple recipients and one of the recipient fields is malformed,
the highlighted field may not be visible due to being scrolled out of view,
leading to a confusing lack of error feedback when clicking Send. To avoid this
problem ensure the first field containing an error is scrolled into view
when Send is clicked.

b9ee63c71b751fd67da777774ea8c0b27e7db2f8 Make descriptor test deterministic (David Reikher)
Pull request description:
This is an improvement to a test, inspired by #14343 - removing non determinism from a test.
The test `descriptor_test` is non-deterministic, as it relies on the `MaybeUseHInsteadOfApostrophy` function which randomly either swaps all apostrophes with 'h' or doesn't at all in a descriptor. This fix makes both cases always run, if an apostrophe is found in a test descriptor.
This does not reduce test coverage but removes the non-determinism.
Additionally, the `MaybeUseHInsteadOfApostrophy` function removed the checksum if found at the end of a descriptor when the apostrophes are swapped by 'h's, since after being swapped the checksum is no longer correct. I instead added re-calculation of the checksum using the `DescriptorChecksum` function, which adds coverage for the case of a descriptors having 'h's instead of apostrophes and a checksum. This was previously lacking.
To achieve this I had to move `DescriptorChecksum` and `PolyMod` out of the anonymous namespace in descriptor.cpp to make `DescriptorChecksum` accessible in descriptor_tests.cpp.
All tests complete successfully (functional as well as unit tests).

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.
