b691f2df5f7d443c0c9ee056ab94aa0fc19566d5 Replace automatic bans with discouragement filter (Pieter Wuille)
Pull request description:
This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned since #14929, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full.
Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers.
Also change the name of this mechanism to "discouraged" to better reflect reality.

Pull request description:
This is another intermediate part of the Coinstats Index (tracked in #18000).
Sjors suggested [here](https://github.com/bitcoin/bitcoin/pull/18000#issuecomment-641423019) that the part of the changes in #19145 that don't rely on the new `hash_type` muhash, i.e. that are for `hash_type=none`, could be merged separately from everything involving muhash. So these changes are extracted from #19145 here and can be merged without any other requirements.
Building the index with no UTXO set hash is still valuable because `gettxoutsetinfo` can still be used to audit the `total_amount` for example. By itself this PR is not a huge improvement, `hash_type=none` is speeding up `gettxoutsetinfo` by about 10%, but it enables the implementation of an index on top of it in a follow-up and that means large parts of the index code of Coinstats Index can be merged while reviews for the hashing algorithm might take longer.

Pull request description:
The utility function is primarily useful to dereference pointer types, which are known to be not null at that time.
For example, the ArgsManager is known to exist when the wallets are started: https://github.com/bitcoin/bitcoin/pull/18923/files#diff-fdb2a1a1d8bc790fcddeb6cf5a42ac55R503 . Instead of silently relying on that assumption, `Assert` can be used to abort the program and avoid UB should the assumption ever be violated.

Pull request description:
Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.
Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.
Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.
As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

1087807b2bc56b9c7e7a5471c83f6ecfae79b048 tests: Provide main(...) function in fuzzer (practicalswift)
Pull request description:
Provide `main(...)` function in fuzzer. Allow building uninstrumented harnesses with only `--enable-fuzz`.
This PR restores the behaviour to how things worked prior to #18008. #18008 worked around an macOS specific issue but did it in a way which unnecessarily affected platforms not in need of the workaround :)
Before this patch:
```
# Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
$ ./configure --enable-fuzz
$ make
CXXLD test/fuzz/span
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Makefile:7244: recipe for target 'test/fuzz/span' failed
make[2]: *** [test/fuzz/span] Error 1
make[2]: *** Waiting for unfinished jobs....
$
```
After this patch:
```
# Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
$ ./configure --enable-fuzz
$ make
$ echo foo | src/test/fuzz/span
$
```
The examples above show the change in non-macOS functionality. macOS functionality is unaffected by this patch.

9b8907faded8e4ec312c0dd4b4b15e1793876acd Check size after Unserializing CPubKey (Elichai Turkel)
Pull request description:
Found by practicalswift, closes#19235
Currently all the public API(except the pointer-like API) in CPubKey that sets/constructs a pubkey goes through `CPubKey::Set` which checks if that the length and size match and if not invalidates the key.
This adds the same check to `CPubKey::Unserialize`, sadly I don't see an easy way to just push this to the existing checks in `CPubKey::Set` but it's only a simple condition.
The problem with not invalidating is that if you write a pubkey like: `{0x02,0x00}` it will think the actual length is 33(because of `size()`) and will access uninitialized memory if you call any of the functions on CPubKey.

Pull request description:
This improves our Span class by making it closer to the C++20 `std::span` one:
* ~~Support conversion between compatible Spans (e.g. `Span<char>` to `Span<const char>`).~~ (done in #18591)
* Make the size type `std::size_t` rather than `std::ptrdiff_t` (the C++20 one underwent the same change).
* Support construction of Spans directly from arrays, `std::string`s, `std::array`s, `std::vector`s, `prevector`s, ... (for all but arrays, this only works for const containers to prevent surprises).
And then make use of those improvements in various call sites.
I realize the template magic used looks scary, but it's only needed to make overload resultion make the right choices. Note that the operations done on values are all extremely simple: no casts, explicit conversions, or warning-silencing constructions. That should hopefully make it simpler to review.

The utility is primarily useful to dereference pointer types, which are
known to be not null at that time.
For example, the ArgsManager is known to exist when the wallets are
started. Instead of silently relying on that assumption, Assert can be
used to abort the program and avoid UB should the assumption ever be
violated.
- Move the decision whether to translate an error message to where it is
defined. This simplifies call sites: no more `InitError(Untranslated(...))`.
- Make all functions in `util/error.h` consistently return a
`bilingual_str`. We've decided to use this as error message type so
let's roll with it.
This has no functional changes: no messages are changed, no new
translation messages are defined.
b00266fe0cf05fe6044f471105ce2bfed4349626 refactor: replace pointers by references within tx_verify.{h,cpp} (Sebastian Falbesoner)
Pull request description:
This PR gets rid of another unnecessary use of raw pointers, similar to PR #19053 (see also issue #19062 where useful commands for finding potential candidates are listed) but in the tx verification module.
For the functions `CalculateSequenceLocks()` and `SequenceLocks()`, the `prevHeights` vector parameter type is changed to be passed as a reference. Note that there were no checks for null pointers -- if one would pass `nullptr` to one of the functions, the following line would immediately lead to a crash:

faa958bc283023334b9377f5fb2210459ca16d82 txindex: Remove unused boost/thread (MarcoFalke)
Pull request description:
There are predefined interruption points for `boost::thread`: https://www.boost.org/doc/libs/1_71_0/doc/html/thread/thread_management.html#interruption_points
However, non-boost threads such as `std::thread` or the `main()` thread can obviously not be interrupted. So remove all unused boost/thread from methods that are never executed in a `boost::thread`.
Most of them were accompanied by a `ShutdownRequested` anyway. So even if the current thread was a `boost::thread`, the interruption point would be redundant. (We only interrupt threads during shutdown)

8b3136bd307123a255b9166aa42a497a44bcce70 refactor: replace CNode pointers by references within net_processing.{h,cpp} (Sebastian Falbesoner)
Pull request description:
This PR is inspired by a [recent code review comment](https://github.com/bitcoin/bitcoin/pull/19010#discussion_r426954791) on a PR that introduced new functions to the net_processing module. The point of the discussion was basically that whenever we pass something not by value (in the concrete example it was about `CNode*` and `CConnman*`) we should either use
* a pointer (```CType*```) with null pointer check or
* a reference (```CType&```)
To keep things simple, this PR for a first approach
* only tackles `CNode*` pointers
* only within the net_processing module, i.e. no changes that would need adaption in other modules
* keeps the names of the variables as they are
I'm aware that PRs like this are kind of a PITA to review, but I think the code quality would increase if we get rid of pointers without nullptr check -- bloating up the code by adding all the missing checks would be the worse alternative, in my opinion.
Possible follow-up PRs, in case this is received well:
* replace CNode pointers by references for net module
* replace CConnman pointers by references for net_processing module
* ...

Telling from the line numbers, it looks like `nMisbehavior` wrapped around.
Fix that by calling `StopNodes` after each exec, which should clear the node state and thus `nMisbehavior`.

Code review ACK f871f15c9d760b56a6a3b78b3941d3983d60810c. Changes look good and thanks for updating. In future would recommend using clang-format-diff and following [coding style](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#coding-style-c) notes, because it's atypical to indent namespace content, or indent protected keywords or put spaces around ::. Also it's fragile to define test setup class in a namespace, but test setup methods outside of the namespace and inside the test fixture instead. Would be simpler to just define the testing setup completely before using it without a namespace like: 8ad5f1c376/src/test/rpc_tests.cpp (L23) and it would have been a slightly smaller change too.
