fa18553d382a7d8c447cd6698b36e293fb7ecf1f fuzz: Remove addrdb fuzz target (MarcoFalke)
Pull request description:
The target has several issues:
* It is named incorrectly (`addrdb`, but it constructs a `CBanEntry`)
* It doesn't do anything meaningful, other than consuming one integer and passing it to a constructor
* It consumes CPU time that can be used for the other targets
* It is redundant with the banman fuzz target
Fix all by removing it.

14e8cf974a7a317796ef8e97e5cf9c355ceff0ee [consensus] MOVEONLY: Move single-sig checking EvalScript code to EvalChecksig (Pieter Wuille)
Pull request description:
This is another small refactor pulled out of the Schnorr/Taproot PR #17977.
This is in preparation for adding different signature verification rules,
specifically tapscript (BIP 342), which interprets opcode 0xac and 0xad
as Schnorr signature verifications.

37ae687f95c82f2d64ed880533d158060d4fc3de Add tests for CPubKey serialization/unserialization (Elichai Turkel)
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.

fb17c99e35e72f3b21ec3b5473e84c21dc964776 guix: Don't include directory name in SHA256SUMS (Andrew Chow)
Pull request description:
The SHA256SUMS file can be used in a sha256sum -c command to verify downloaded binaries. However users are likely to download just a single file and not place this file in the correct directory relative to the SHA256SUMS file for the simple verification command to work. By not including the directory name in the SHA256SUMS file, it will be easier for users to verify downloaded binaries.

Pull request description:
Based on: #21462
Keeping the README in one file so that it's easy to search through. Will add more jumping links later so navigation is easier.
Current TODOs:
- [x] Shell installer option: prompt user to re-login for `/etc/profile.d` entry to be picked up
- [x] Binary tarball option: prompt user to create `/etc/profile.d` entry and re-login
- [x] Fanquake docker option: complete section
- [x] Arch Linux AUR option: prompt to start `guix-daemon-latest` unit after finishing "optional setup" section
- [x] Building from source option: Insert dependency tree diagram that I made
- [x] Building from source option: redo sectioning, kind of a mess right now
- [x] Optional setup: make clear which parts are only needed if building from source
- [x] Workaround 1 for GnuTLS: perhaps mention how to remove Guix build farm's key
- [x] Overall (after everything): Make the links work.
Note to self: wherever possible, tell user how to check that something is true rather than branching by installation option.

ACK fac4814106c796b8786dd90053513cc35142dfe5 - going to go ahead and merge this now. It's a lot of documentation, and could probably be nit-picked / improved further, however, that can continue over the next few weeks. I'm sure more (backportable) improvements / clarifications will be made while we progress through RCs towards a new release.

29c9e2c2d2015ade47ed4497926363dea3f9c59b wallet: Do not iterate a directory if having an error while accessing it (Hennadii Stepanov)
Pull request description:
On Windows when `ListDatabases` tries to iterate any system folder, e.g., "System Volume Information", it falls into an infinite loop.
This PR fixes this bug. Now the `debug.log` contains:
```
2021-05-12T09:07:53Z ListDatabases: Access is denied D:/System Volume Information -- skipping.
```
An easy way to reproduce the bug and test this PR is to pass the `-walletdir=D:\` command-line option, and run the `listwalletdir` RPC, or File -> Open Wallet in the GUI menu.
Fixes#20081.
Fixes#21136.
Fixes#21904.

Pull request description:
It is debatable whether a size of the median filter other than `200` (the only size used in production) should be fuzzed. For now add a minimal patch to cap the max insertions. Otherwise the complexity is N^2 log(N), where N is the size of the fuzz input.

Pull request description:
Closes: #21242
```
Reproduced from depends/Makefile comment:
When invoking a shell, GNU Make special-cases exit code 127 (command not
found) by not capturing the output but instead passing it through. This
is not done for any other exit code.
Therefore, we require a "|| true" to avoid this behaviour when in an
environment where the build_* or host_* may not exist yet.

In #21415 [we decided](https://github.com/bitcoin/bitcoin/pull/21415#issuecomment-800236640) to return `std::optional` rather than `{}` for

with `std::nullopt`.
As a side-effect, this also quells the spurious GCC 10.2.x warning that
we've had reported quite a few times. i.e #21318, #21248, #20797.

9086e0dd3c924b6c9a5ad05799d30d97b9ced3be build: set Unicode true for NSIS installer (fanquake)
Pull request description:
Now that we are using Focal for gitian builds, and have [NSIS 3.0+ available](https://packages.ubuntu.com/focal/nsis) (also in Guix), we can create installers that [support unicode](https://nsis.sourceforge.io/Docs/Chapter4.html#aunicodetarget).
Unicode is only becoming the NSIS default [beginning with the 3.07 release](https://nsis.sourceforge.io/Docs/AppendixF.html#v3.07-cl), so we need to set this attribute to get support.
Should close: #13817

## Issue being fixed or feature implemented
the problem with retries implemented in #4793 is that they don't really
do anything besides fetching results of a failed job multiple times 🙈
## What was done?
partially reverted changes done in #4793, implemented actual job
restart. dropped `--sleep` and `--retries` and added `--attempts`
instead.
## How Has This Been Tested?
Pick any test, add some randomly failing expression somewhere and run it
with some high number of retries.
For example:
```diff
diff --git a/test/functional/feature_dip0020_activation.py b/test/functional/feature_dip0020_activation.py
index 471e4fdc66..b56a954b78 100755
--- a/test/functional/feature_dip0020_activation.py
+++ b/test/functional/feature_dip0020_activation.py
@@ -69,6 +69,7 @@ class DIP0020ActivationTest(BitcoinTestFramework):
# Should be spendable now
tx0id = self.node.sendrawtransaction(tx0_hex)
assert tx0id in set(self.node.getrawmempool())
+ assert int(tx0id[0], 16) < 4
if __name__ == '__main__':
```
On develop:
```
./test/functional/test_runner.py feature_dip0020_activation.py --retries=100 --sleep=0
```
if this fails on the first run, it keeps "failing" (simply fetching the
same results actually) till the end.
With this patch:
```
./test/functional/test_runner.py feature_dip0020_activation.py --attempts=100
```
if this fails on the first run, it can actually succeed after a few
attempts now, unless you are extremely unlucky ofc 😄

## Issue being fixed or feature implemented
## What was done?
Added v20 BIP9 style fork structure along with utility functions.
Since several features coming depending on that fork status, we needed
to group them into one
