982e548a9a78b1b0abad59b54c780b6b06570452 Don't set BDB flags when configuring without (Jonas Schnelli)
Pull request description:
Configuring `--without-bdb` on MacOS leads to a compile error (when BerkeleyDB is not installed). `brew --prefix berkeley-db4` always reports the target directory (even if not installed).
This PR prevents BDB_CFLAGS (et al) from being populated when configuring `--without-bdb`

076183b36b76a11438463883ff916f17aef9e001 build: add -fcf-protection=full to hardening options (fanquake)
Pull request description:
Beginning with Ubuntu `19.10`, it's packaged GCC now has some additional hardening options enabled by default (in addition to existing defaults like `-fstack-protector-strong` and reducing the minimum ssp buffer size). The new additions are`-fcf-protection=full` and `-fstack-clash-protection`.
> -fcf-protection=[full|branch|return|none]
> Enable code instrumentation of control-flow transfers to increase program security by checking that target addresses of control-flow transfer instructions (such as indirect function call, function return, indirect jump) are valid. This prevents diverting the flow of control to an unexpected target. This is intended to protect against such threats as Return-oriented Programming (ROP), and similarly call/jmp-oriented programming (COP/JOP).
> -fstack-clash-protection
> Generate code to prevent stack clash style attacks. When this option is enabled, the compiler will only allocate one page of stack space at a time and each page is accessed immediately after allocation. Thus, it prevents allocations from jumping over any stack guard page provided by the operating system.
If your interested you can grab `gcc-9_9.3.0-10ubuntu2.debian.tar.xz` from https://packages.ubuntu.com/focal/g++-9. The relevant changes are part of the `gcc-distro-specs` patches, along with the relevant additions to the gcc manages:
> NOTE: In Ubuntu 19.10 and later versions, -fcf-protection is enabled by default for C, C++, ObjC, ObjC++, if none of -fno-cf-protection nor -fcf-protection=* are found.
> NOTE: In Ubuntu 19.10 and later versions, -fstack-clash-protection is enabled by default for C, C++, ObjC, ObjC++, unless -fno-stack-clash-protection is found.
So, if you're C++ using GCC on Ubuntu 19.10 or later, these options will be active unless you explicitly opt out. This can be observed with a small test:
```c++
int main() { return 0; }
```
```bash
g++ --version
g++ (Ubuntu 9.3.0-10ubuntu2) 9.3.0
g++ test.cpp
objdump -dC a.out

113b: 00 00 00
113e: 66 90 xchg %ax,%ax
```
Note the insertion of an `endbr64` instruction when compiling and _not_ opting out. This instruction is part of the Intel Control-flow Enforcement Technology [spec](https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf), which the GCC control flow implementation is based on.
If we're still doing gitian builds for the `0.21.0` and `0.22.0` releases, we'd likely update the gitian image to Ubuntu Focal, which would mean that the GCC used for gitian builds would also be using these options by default. So we should decide whether we want to explicitly turn these options on as part of our hardening options (although not just for this reason), or, we should be opting-out.
GCC has supported both options since 8.0.0. Clang has supported `-fcf-protection` from 7.0.0 and will support `-fstack-clash-protection` in it's upcoming [11.0.0 release](https://clang.llvm.org/docs/ReleaseNotes.html#id6).

8578c6fccd11404412d2c60f9bede311b79ca0d0 build: Fix search for brew-installed BDB 4 on OS X (Glenn Willen)
Pull request description:
~~NOTE: This PR contains one important fix that I need (to make Bitcoin Core build cleanly on my system without shenanigans), plus some related general cleanup that is not really necessary, and could be annoying. (I am prepared to defend my argument that BDB_CFLAGS is wrong here, and BDB_CPPFLAGS is right, but this could bite anybody who has gotten in the habit of -- or scripted -- setting the former.)~~
Ok, I have been convinced that I was too clever with the refactor and I have removed it. Now it's just the tiny change to fix the build on my local machine.
---
On OS X, when searching Homebrew keg-only packages for BDB 4.8, if we find it,
use BDB_CPPFLAGS and BDB_LIBS instead of CFLAGS and LIBS for the result. This
is (1) more correct, and (2) necessary in order to give this location
priority over other directories in the include search path, which may include
system include directories with other versions of BDB.

Pull request description:
Given that we went through a [gitian build](https://github.com/bitcoin/bitcoin/pull/18681) to remember why this is the case, we might as well make a note of it in configure.ac.
[From #18681](https://github.com/bitcoin/bitcoin/pull/18681#issuecomment-615526634):
Looking at the Linux build log, this has failed with:
```bash

```
`__cxa_thread_atexit_impl` is used for [thread_local variable destruction](https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables):
> To implement this support, glibc defines __cxa_thread_atexit_impl exclusively for use by libstdc++ (which has the __cxa_thread_atexit to wrap around it), that registers destructors for thread_local variables in a list. Upon thread or process exit, the destructors are called in reverse order in which they were added.
As suggested, this only became available in glibc 2.18. From the [2.18 release notes](https://sourceware.org/legacy-ml/libc-alpha/2013-08/msg00160.html):
> * Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.

Remove backticks - Their usage for the `bdb_prefix` and `qt5_prefix` commands may have improved backwards compatibility in some cases, however we now require recent versions of macOS. I'm not sure why they were being used in the `HAVE_STD__SYSTEM` and `HAVE_WSYSTEM` defines.

8f7b93047581c67f2133cdb8c7845471de66c30f 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.

e90e3e684ffa7b25f0dfb5b45e70bb0c358261fb build: fix sysctl() detection on macOS (fanquake)
Pull request description:
[`sysctl()` on *BSD](https://www.unix.com/man-page/FreeBSD/3/sysctl/) takes a "const int *name", whereas [`sysctl()` on macOS](https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/sysctl.3.html)
it takes an "int *name". So our configure check and `sysctl()` detection on
macOS currently fails:
```bash
/usr/include/sys/sysctl.h:759:9: note: candidate function not viable:
no known conversion from 'const int [2]' to 'int *' for 1st argument
int sysctl(int *, u_int, void *, size_t *, void *, size_t);
```
The simplest change seems to be to change the param to a "int *name", which
will work during configure on macOS and *BSD systems.
For consistency I've changed both calls, but note that macOS doesn't
have `KERN_ARND`, so that check will always fail regardless. We can revert/add
documentation if preferred.

f2747d1602ec4e1128356b861b2167daf66a845b build: Restrict check for CRC32C intrinsic to aarch64 (W. J. van der Laan)
Pull request description:
`crc32c`'s hardware accelerated code doesn't handle ARM 32-bit at all, but only 64-bit. Make the check in `configure.ac` check for this architecture explicitly. This change does not affect non-ARM architectures.
For the release binaries, the current `configure.ac` check happens to work: it enables it on aarch64 but disables it for armhf. However some combination of compiler version and settings can cause this check to succeed on armhf (as reported on IRC). So make the 64-bit platform requirement explicit.
(details: while the check already explicitly checks the `__crc32d` intrinsic, which strictly doesn't exist on 32-bit ARM, this is not enough! gcc happens to helpfully emulate it:
> These built-in intrinsics for the ARMv8-A CRC32 extension are available when the -march=armv8-a+crc switch is used "uint32_t __crc32d (uint32_t, uint64_t)" Form of expected instruction(s): Two crc32w r0, r0, r0 instructions for AArch32

- [x] Resolve the reported warnings. (819d03b932134ee91df3b0fe98a481a331ce57bf)
Currently, enabling this flag no longer reports the following warnings:

Pull request description:
This has been around since the introduction of autotools. However at
this point I'm not sure we'd ever want to suppress all warnings when
performing a build, and given that CXX FLAGS will have been overriden
when cross-compiling for Windows (using depends), this would rarely,
if-ever be used anyways.
