67d99900b0d770038c9c5708553143137b124a6c make SaltedOutpointHasher noexcept (Martin Ankerl)
Pull request description:
If the hash is not `noexcept`, `unorderd_map` has to assume that it can throw an exception. Thus when rehashing care needs to be taken. libstdc++ solves this by simply caching the hash value, which increases memory of each node by 8 bytes. Adding `noexcept` prevents this caching. In my experiments with `-reindex-chainstate -stopatheight=594000`, memory usage (maximum resident set size) has decreased by 9.4% while runtime has increased by 1.6% due to additional hashing. Additionally, memusage::DynamicUsage() is now more accurate and does not underestimate.

efd2474d17098c754367b844ec646ebececc7c74 util: CBufferedFile fixes (Larry Ruane)
Pull request description:
The `CBufferedFile` object guarantees its user is able to "rewind" the data stream (that's being read from a file) up to a certain number of bytes, as specified by the user in the constructor. This guarantee is not honored due to a bug in the `SetPos` method.
Such rewinding is done in `LoadExternalBlockFile()` (currently the only user of this object), which deserializes a series of `CBlock` objects. If that function encounters something unexpected in the data stream, which is coming from a `blocks/blk00???.dat` file, it "rewinds" to an earlier position in the stream to try to get in sync again. The `CBufferedFile` object does not actually rewind its file offset; it simply repositions its internal offset, `nReadPos`, to an earlier position within the object's private buffer; this is why there's a limit to how far the user may rewind.
If `LoadExternalBlockFile()` needs to rewind (call `blkdat.SetPos()`), the stream may not be positioned as it should be, causing errors in deserialization. This need to rewind is probably rare, which is likely why this bug hasn't been noticed already. But if this object is used elsewhere in the future, this could be a serious problem, especially as, due to the nature of the bug, the `SetPos()` _sometimes_ works.
This PR adds a unit test for `CBufferedFile` that fails due to this bug. (Until now it has had no unit tests.) The unit test provides good documentation and examples for developers trying to understand `LoadExternalBlockFile()` and for future users of this object.
This PR also adds code to throw an exception from the constructor if the rewind argument is not less than the buffer size (since that doesn't make any sense).
Finally, I discovered that the object is too restrictive in one respect: When the deserialization methods call this object's `read` method, a check ensures that the number of bytes being requested is less than the size of the buffer (adjusting for the rewind size), else it throws an exception. This restriction is unnecessary; the object being deserialized can be larger than the buffer because multiple reads from disk can satisfy the request.

2457aea83c1f9fba708e2335bb197950bf0b6244 Assert that the HRP is lowercase in Bech32::Encode (Samuel Dobson)
Pull request description:
From BIP-173:
> The lowercase form is used when determining a character's value for checksum purposes.
> Encoders MUST always output an all lowercase Bech32 string. If an uppercase version of the encoding result is desired, (e.g.- for presentation purposes, or QR code use), then an uppercasing procedure can be performed external to the encoding process.
Currently if HRP contains uppercase characters, the checksum will be generated over these uppercase characters resulting in mixed-case output that will always be invalid even if the case is changed manually after encoding. This shouldn't happen because both prefix's `bc` and `tb` are lowercase currently, but we assert this condition anyway.
This is consistent also with the [C reference implementation](2b0aac650c/ref/c/segwit_addr.c (L59))

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.

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.

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]

Pull request description:
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.

This directory is automatically created by the build process (in the build target directory, see #16588) and doesn't need to be in the repository nor in the tarballs.
Move associated ignore directive to top-level `.gitignore` file.
