8a3b2eb175 move-only: move coins statistics utils out of RPC (James O'Beirne)
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/master/proposal
---
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.

Pull request description:
Related to #16354.
This PR adds additional configure flags to packages in depends to explicitly disable features we aren't using; similar to #16183. It also fixes passing `--without-tools` to `qrencode`.
I've added `--disable-drafts` to `zeromq`:
```bash
Build and install draft classes and methods [default=yes]
```
I'm not entirely sure how far we want to take this. i.e in the `zeromq` package we explicitly pass `--without-libsodium`, even though it's disabled by default.
Do we also want to explicitly pass all the other `--without` flags? :
```bash
--with-libgssapi_krb5 require libzmq build with libgssapi_krb5
[default=no]
--with-libsodium use libsodium instead of built-in tweetnacl
[default=no]
--with-pgm build libzmq with PGM extension. Requires pkg-config
[default=no]
--with-norm build libzmq with NORM protocol extension,
optionally specifying norm path [default=no]
--with-vmci build libzmq with VMCI transport [default=no]
```

e7415a5a95 Doc: move detached release notes into release-notes.md (David A. Harding)
Pull request description:
Merges in detached release notes, edits each change down to a single paragraph bullet point (or, in a couple cases, two individual bullet points in separate sections each with a single paragraph). Adds notes for some undocumented changes I found reviewing `git log --merges`. Also tries something new: adds the PR number(s) after each entry to make it easier for both reviewers and end-user readers to look up the details behind each change. (If the PR numbers are unwanted, they're easy to remove either in this PR or later in the release process.)
I also checked the 0.18 branch but I didn't find anything in the current release notes that had been backported.
A particular focus in my editing was trying to keep things concise, particularly by pointing to RPC documentation when available (or upcoming, as in #16629). I do suspect that one downside of detached notes is that people write longer summaries than they would if they knew there were already 300 other lines of release notes. :-)
The first commit only moves notes, puts them in bullet form, adjusts indentation appropriately, and drops unneeded headers. It can be reviewed with `git diff --color-moved=dimmed-zebra` for a little bit of a speedup, but unfortunately I wasn't smart enough to split my copy/pasting and line wrapping into separate commits, so it's not a transparently move-only change.

Rebased and squashed #14956.
> 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. This results in a confusing lack of error feedback.
> Avoid this problem by ensuring the first field containing an error is scrolled into view when Send is clicked.
You can see the behavior here: https://imgur.com/a/QZG5TQc
How to test:
Add a few recipients and give any of them an invalid address or amount. Scroll the invalid recipient out of view and hit Send. With this change, the GUI will scroll to show the invalid recipient, with master it will not, "hiding" the error.

b9ee63c71b 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).

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.

6011c9d72d QA: fix rpc_setban.py race (Jonas Schnelli)
Pull request description:
The new `rpc_setban.py` test failes regularly on CIs due to a race between injecting the ban and testing the log "on the other side".
The problem is, that the test immediately after the `addnode` command on node0 checks for the `dropped (banned)` entry on node1 (without giving some time).
Adding a 2 seconds sleep seems to solve the race (I guess there is no better event-driven delay).
Example of a failed test: https://bitcoinbuilds.org/index.php?ansilog=bf743910-103f-4b54-9a97-960c471061bd.log#l2906

2dbfb37b40 Fix Char as Bool in interfaces (Jeremy Rubin)
Pull request description:
In a few places in src/wallet/wallet.h, we use a char when semantically we want a bool.
This is kind of an issue because it means we can unserialize the same transaction with different fFromMe flags (as differing chars) and evaluate the following section in wallet/wallet.cpp
```c++
if (wtxIn.fFromMe && wtxIn.fFromMe != wtx.fFromMe)
{
wtx.fFromMe = wtxIn.fFromMe;
fUpdated = true;
}
```
incorrectly (triggering an fUpdated where both fFromMe values represent true, via different chars).
I don't think this is a vulnerability, but it's just a little messy and unsemantic, and could lead to issues with stored wtxIns not being findable in a map by their hash.
The serialize/unserialize code for bool internally uses a char, so it should be safe to make this substitution.
NOTE: Technically, this is a behavior change -- I haven't checked too closely that nowhere is depending on storing information in this char. Theoretically, this could break something because after this change a tx unserialized with such a char would preserve it's value, but now it is converted to a ~true~ canonical bool.

Changed MaybeUseHInsteadOfApostrophy to UseHInsteadOfApostrophe.
This function now always replaces apostrophes with 'h'.
The original Check function was renamed to DoCheck and it's
called with an additional parameter which tells it to either
leave the prv and pub arguments as is or replace the apostrophes
with 'h'. The test runs with apostrophes replaced in prv only,
pub only, prv and pub and without replacement at all. Replacement
of apostrophes in a descriptor and then running DoCheck is conditional
on whether apostrophes are found in that descriptor.
Additionally, instead of dropping the checksum recalculate it
after replacing apostrophes with 'h' in the function UseHInsteadOfApostrophe
using the GetDescriptorChecksum function. That way, this also
introduces an indirect unit test to GetDescriptoChecksum.

20ea9ef6ce [doc] mention whitelist is inbound, and applies to blocksonly (Sjors Provoost)
Pull request description:
* `-whitelist` only impacts inbound nodes (see #9923). This is obvious in the context of allowing those nodes to connect to you, but there are additional whitelist features where this is less obvious, such as mempool relay behavior.
* `whitelistrelay` (on by default) explains that `-blocksonly` makes an exception for transactions from whitelisted nodes, but it wasn't documented (nor obvious imo) the other way around. See also https://github.com/bitcoin/bitcoin/pull/15984#issuecomment-490645552
