a0a771843f contrib: Changes to checks for PowerPC64 (Luke Dashjr)
634f6ec4eb contrib: Parse ELF directly for symbol and security checks (Wladimir J. van der Laan)
Pull request description:
Instead of the ever-messier text parsing of the output of the readelf tool (which is clearly meant for human consumption not to be machine parseable), parse the ELF binaries directly.
Add a small dependency-less ELF parser specific to the checks.
This is slightly more secure, too, because it removes potential ambiguity due to misparsing and changes in the output format of `elfread`. It also allows for stricter and more specific ELF format checks in the future.
This removes the build-time dependency for `readelf`.
It passes the test-security-check for me locally, ~~though I haven't checked on all platforms~~. I've checked that this works on the cross-compile output for all ELF platforms supported by Bitcoin Core at the moment, as well as PPC64 LE and BE.

xorriso and its mkisofs/genisoimage emulation alter-ego xorrisofs are
more maintained, and has the right toggles for us to achieve output
determinism without using blunt tools like faketime.
In this commit, we use xorrisofs from the build environment rather than
building it ourselves using depends. This is not necessary and can be
changed in the future.
From https://wiki.debian.org/genisoimage?action=recall&rev=11 :
> The classical command line interface for production of ISO 9660
> filesystem images is the option set established by program mkisofs.
> For reasons of licensing and other problems with its author, Debian
> ships a fork of mkisofs, called genisoimage, which was split off in
> 2006 and then developed independently.
>
> Meanwhile, genisoimage gets no new features and not even bug fixes. It
> is first choice only if its options -udf or -hfs are needed.
>
> Replacement in most uses cases, especially for bootable ISO 9660
> filesystems, archiving, and backup, is xorrisofs which starts the -as
> mkisofs emulation mode of program xorriso.
Previously, the compression of the .iso file to a .dmg file was done
outside of `make deploy' in order to use the faketime-wrapped version of
libdmg-hfsplus's DMG tool.
Specifying the faketime-wrapped version of the DMG tool to ./configure
fixes this and simplifies build scripts.

Pull request description:
This consolidates our macOS build code so that `.DS_Store` generation is the same when running `make deploy` for macOS when building on Linux and macOS, rather than maintaining two version of code that essentially do the same thing (just slightly differently).
It also removes unused code and any AppleScript usage, automates finding translation files and generally simplifies `macdeployqtplus`. It also gets rid of the annoying "popping up" behaviour during DMG generation, names the created image `Bitcoin-Core.dmg` rather than `Bitcoin-Qt.dmg`.

ACK b685f60a08 - Less and cleaner code looks good. I tested this with `make deploy` and everything still works + the popup during DMG generation is gone.

- Added `--version` flag to bitcoin-tx to match.
- Added functionality in gen-manpages.sh to error when attempting to generate man pages for binaries built from a dirty branch.

Check both failure cases:
- Use a glibc symbol from a version that is too new
- Use a symbol from a library that is not in the allowlist
And also check a conforming binary.
Adding a similar check for Windows PE can be done in a separate PR.
Rather than two lots of logic doing roughly the same thing, dependent on if
you're compiling on Linux or macOS, combine the .DS store generation into
macdeployqtplus.
This also removes the -fancy and -volname options.
Rather than using OSX_QT_TRANSLATIONS which must be manually updated,
and we forget to update anyway, i.e: #19059, automatically find and copy
available translations from the translations directory.
Adjusted version flag behavior in bitcoin-tx, bitcoin-wallet, and
bitcoind to match. Added functionality in gen-manpages.sh to warning when
attempting to generate man pages for binaries built from a dirty
branch.
a52ecc936a build: set minimum supported macOS to 10.14 (fanquake)
Pull request description:
This is a requirement for C++17 support. See my comments [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643722538):
> You cannot use std::get with std::variant on macOS < 10.14, because Apples libc++ doesn't support the std::bad_variant_access exception. [Relevant comment](https://github.com/bitcoin/bitcoin/pull/19183#discussion_r439794318) in #19183.
> While we could work around this in our own code, using std::get_if, this would still be a problem for 3rd-party dependencies.
> I've been testing Qt 5.15LTS (we'll have to enable C++17 in qt, and may upgrade to a newer version at the same time), and you can't enable -std c++17, while targeting a macOS deployment version < 10.14, configuring will fail. They are making use of std::get with std::variant throughout their cocoa code.
We would have to had to have bumped to at least 10.13 in any case, as Qt 5.15 (#19716) [requires 10.13+](https://doc.qt.io/qt-5/supported-platforms.html).

8f7b930475 Drop the leading 0 from the version number (Andrew Chow)
Pull request description:
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, as the Major version was 0 so it never actually got included in it.
The user agent string formatter is updated to follow this new versioning.
***
Honestly I'm just tired of all of the people asking for "1.0" that maybe this'll shut them up. Skip the whole 1.0 thing and go straight to version 22.0!
Also, this means that the terminology we commonly use lines up with how the variables are named. So major versions are actually bumping the major version number, etc.

b6121edf70 swapped "is" for "==" in literal comparison (Tyler Chambers)
