fabb6dfe6e script: Replace address-of idiom with vector data() method (Guido Vranken)
Pull request description:
The main theme of this refactor is to replace `&foo[0]` with `foo.data()`.
The first commit is taken from #21781 with the rationale:
* In CSignatureCache::ComputeEntryECDSA, change the way a vector pointer is resolved to prevent invoking undefined behavior if the vector is empty.
The other commits aim to remove all `&foo[0]`, where `foo` is any kind of byte representation. The rationale:
* Sometimes alternative code without any raw data pointers is easier to read (refer to the respective commit message for details)
* If the raw data pointer is needed, `foo.data()` should be preferred, as pointed out in the developer notes. This addresses the instances that have been missed in commit 592404f03f, and https://github.com/bitcoin/bitcoin/pull/9804

46b025e00d test: add new python linter to check file names and permissions (windsok)
6f6bb3ebc7 test: fix file permissions on various scripts (windsok)
Pull request description:
Adds a new python linter test which tests for correct filenames and file permissions in the repository.
Replaces the existing tests in the `test/lint/lint-filenames.sh` and `test/lint/lint-shebang.sh` linter tests, as well as adding some new and increased testing. This increased coverage is intended to catch issues such as in #21728 and https://github.com/bitcoin/bitcoin/pull/16807/files#r345547050
Summary of tests:
* Checks every file in the repository against an allowed regexp to make sure only lowercase or uppercase alphanumerics (a-zA-Z0-9), underscores (_), hyphens (-), at (@) and dots (.) are used in repository filenames.
* Checks only source files (*.cpp, *.h, *.py, *.sh) against a stricter allowed regexp to make sure only lowercase alphanumerics (a-z0-9), underscores (_), hyphens (-) and dots (.) are used in source code filenames. Additionally there is an exception regexp for directories or files which are excepted from matching this regexp (This should replicate the existing `test/lint/lint-filenames.sh` test)
* Checks all files in the repository match an allowed executable or non-executable file permission octal. Additionally checks that for executable files, the file contains a shebang line.
* Checks that for executable `.py` and `.sh` files, the shebang line used matches an allowable list of shebangs (This should replicate the existing `test/lint/lint-shebang.sh` test)
* Checks every file that contains a shebang line to ensure it has an executable permission
Additionally updates the permissions on various files to comply with the new tests.

This PR was motivated by a comment in GUI PR (257) regarding a suggested improvement not being supported by VS2017.
When checking whether master can still be built with the VS2017 toolset ABI issues were encountered. Most likely due to the pre-compiled Qt binaries that are used.
It does not seem worth the effort to try and support VS2017, which would most likely require additional Qt binaries, or lengthy instructions on how to build static Qt binaries on Windows (which is very error prone and tedious).
Added advisory note about build not working with earlier Visual Studio versions.
Fixed grammar.
9bd3f35003 build: adds switch for disabling random base addresses in MSVC (Ethan Heilman)
Pull request description:
In m4 builds we have the --disable-hardening switch that can be given in `./configure` to turn off randomized addresses. This PR provides a simple way of turning off randomized addresses in MSVC builds.
This PR:
* Adds this option the common-init project file so that it can be globally set across the project
* Documents this switch in msvc build readme
I have run the following test to verify this works
I ran the msvc build with `<RandomizedBaseAddress>true</RandomizedBaseAddress>` then checked `bitcoind.exe` and `bitcoin-cli.exe` with `dumpbin.exe`:

These were added as part of #9366 to fix issues with Protobuf.
Now that we no-longer use Protobuf, there's no reason to maintain a
duplicate set of byteswap tests for qt.
This adds a `-daemonwait` flag that does the same as `-daemon` except
it, from a user perspective, backgrounds the process only after
initialization is complete.
This can be useful when the process launching bitcoind wants to
guarantee that either the RPC server is running, or that initialization
failed, before continuing. The exit code indicates the initialization
result.
This replaces the use of the libc function `daemon()` by a custom
implementation which is inspired by the glibc implementation, but also
creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is
that no MACOS-specific pragmas are needed anymore to silence a
deprecation warning.

Pull request description:
Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).
This PR lets `bitcoind` call an arbitrary command `-signer=<cmd>`, e.g. a hardware wallet driver, where it can fetch public keys, ask to display an address, and sign a transaction (using PSBT under the hood).
It's design to work with https://github.com/bitcoin-core/HWI, which supports multiple hardware wallets. Any command with the same arguments and return values will work. It simplifies the manual procedure described [here](https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md).
Usage is documented in [doc/external-signer.md](
https://github.com/Sjors/bitcoin/blob/2019/08/hww-box2/doc/external-signer.md), which also describes what protocol a different signer binary should conform to.
Use `--enable-external-signer` to opt in, requires Boost::Process:
```
Options used to compile and link:
with wallet = yes
with gui / qt = no
external signer = yes
```
It adds the following RPC methods:
* `enumeratesigners`: asks <cmd> for a list of signers (e.g. devices) and their master key fingerprint
* `signerdisplayaddress <address>`: asks <cmd> to display an address
It enhances the following RPC methods:
* `createwallet`: takes an additional `external_signer` argument and fetches keys from device
* `send`: automatically sends transaction to device and waits
Usage TL&DR:
* clone HWI repo somewhere and launch `bitcoind -signer=../HWI/hwi.py`
* check if you can see your hardware device: `bitcoin-cli enumeratesigners`
* create wallet and auto import keys `bitcoin-cli createwallet "hww" true true "" true true true`
* display address on device: `bitcoin-cli signerdisplayaddress ...`
* to spend, use `send` RPC and approve transaction on device
Prerequisites:
- [x] #21127 load wallet flags before everything else
- [x] #21182 remove mostly pointless BOOST_PROCESS macro
Potentially useful followups:
- GUI support: bitcoin-core/gui#4
- bumpfee support
- (automatically) verify (a subset of) keys on the device after import, through message signing

This option replaces --with-boost-process
This prepares external signer support to be disabled by default.
It adds a configure option to enable this feature and to check
if Boost::Process is present.
This also exposes ENABLE_EXTERNAL_SIGNER to the test suite via test/config.ini
Tidied up debug and release configuration blocks in common project file to avoid duplication.
Updated appveyor config to use latest Visual Studio 2019 image.
Changed appveyor config file hash to use a new version of Qt pre-compiled binaries built for Visual Studio 2019 v16.8.1.
Bumped vcpkg version to tag '2020.11-1' for binary caching feature.

Removes the leading 0 from the version number. The minor version, which
we had been using as the major version, is now the major version. The
revision, which we had been using as the minor version, is now the minor
version. The revision number is dropped. The build number is promoted to
being part of the version number. This also avoids issues where it was
accidentally not included in the version number.
The CLIENT_VERSION remains the same format as previous as previously,
the Major version was 0 so that was never a factor in CLIENT_VERSION.

This enables the schnorrsig module in libsecp256k1, adds the relevant types
and functions to src/pubkey, as well as in higher-level `SignatureChecker`
classes. The (verification side of the) BIP340 test vectors is also added.
The vcpkg tool has introduced a proper way to use manifests, https://devblogs.microsoft.com/cppblog/vcpkg-accelerate-your-team-development-environment-with-binary-caching-and-manifests/. This PR replaces the custom text file mechanism with the new manifest approach.
It is planned that vckpg manifests will include the ability to version dependencies in the future. Dependency versions would solve a number of issues that currently require workarounds with the appveyor CI.
Set vcpkg manifest version to 1 to avoid any perception it's related to any release or other version numbering.
The way we currently test with AC_CHECK_DECLS do not work with Clang:
```bash
configure:21492: clang++-10 -std=c++11 -c -g -O2 -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS conftest.cpp >&5
conftest.cpp💯10: error: builtin functions must be directly called
(void) __builtin_clz;
^
1 error generated.
```
This also removes the __builtin_clz() check, as we don't actually use
it anywhere, and it's trvial to re-add detection if we do start using
it at some point.
Add a "PSBT Operations" dialog, reached from the "Load PSBT..." menu
item, giving options to sign or broadcast the loaded PSBT as
appropriate, as well as copying the result to the clipboard or saving
it to a file.

Pull request description:
This fixes compile errors trying to build bitcoin-tx and bitcoin-wallet without libevent, which were reported by Luke Dashjr in https://github.com/bitcoin/bitcoin/issues/18465
The fix avoiding `bitcoin-tx` dependency on libevent just adds a conditional build rule. This is implemented in the first commit (more details in commit description).
The fix avoiding `bitcoin-wallet` dependency on libevent requires minor code changes, because `bitcoin-wallet` (unlike `bitcoin-tx`) links against code that calls `urlDecode` / `evhttp_uridecode`. This fix is implemented in the second commit (again details in the commit description).
