399d84da3708719b063953107bab0f5f6493addb build: Only allow ASCII identifiers (Wladimir J. van der Laan)
Pull request description:
While emoji and other symbols in C++ identifers (as accepted by newer compilers) are fun, they might create confusion during code review, for example because some symbols look very similar. Forbid such extended identifiers for now.
This is done by providing `-fno-extended-identifiers`. Thanks to sipa for suggesting this compiler flag.

e8a8cff07c409c7eecd478d3df36c7ba92c59730 build: enforce minimum required Windows version (7) (fanquake)
Pull request description:
Instruct the linker to set the major & minor subsystem versions in the PE
header to 6 & 1 (NT 6.1 which corresponds to Windows 7). Similar to
the behaviour on macOS, the binary will now refuse to run on
unsupported versions of Windows, which, for us, is XP & Vista.

cd24f37ea9168bd56b8c518ea6125e242cc4213d doc: Better explain GNU ld's dislike of ld64's options (fanquake)
Pull request description:
There's also now more than a single option being special cased for
darwin. If we didn't special case these options they would still end
up on the link line and the binaries produced would just segfault.
I'm going to plug #17874 here as well, because adding
`-fatal-warnings` to our `AX_CHECK_LINK_FLAG` calls would
mostly prevent this sort of option mangling from happening.
An example of the warning behaviour:
```bash
echo "int main() {}" | g++ -x c++ -std=c++11 -Wl,-dead_strip -
/usr/bin/ld: warning: cannot find entry symbol ad_strip; defaulting to 0000000000001040

acd644b83d789a6cdfbeda19732119534d10058e build: remove --large-address-aware linker flag (fanquake)
Pull request description:
This flag was used when building 32-bit Windows executables, which we no-longer
do, and is not accepted by the linker for any of the hosts we currently build
for. i.e:
```bash
checking whether the linker accepts -Wl,--large-address-aware... no
```
--large-address-aware
If given, the appropriate bit in the "Characteristics" field of the COFF
header is set to indicate that this executable supports virtual addresses
greater than 2 gigabytes. This should be used in conjunction with the /3GB
or /USERVA=value megabytes switch in the "[operating systems]" section of
the BOOT .INI. Otherwise, this bit has no effect. [This option is specific
to PE targeted ports of the linker]
You can check that the appropriate bit in the COFF header of our 64-bit
Windows binaries is still be set using dumpbin. i.e:
```powershell
dumpbin /headers .\bitcoind.exe
FILE HEADER VALUES
<snip>
26 characteristics
Executable
Line numbers stripped
Application can handle large (>2GB) addresses

41a413b31746cc749f3c64ed8070cea9cc6cfdbe Define correct symbols for getauxval (Jonas Schnelli)
Pull request description:
PR #20358 made use of the two preprocessor symbols `HAVE_STRONG_GETAUXVAL` as well as `HAVE_WEAK_GETAUXVAL`.
These symbols have not been defined in configure.ac. They where only passed selective as CRC32 CPPFLAGS in https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.crc32c.include#L16.
PR #20358 would have broken the macOS build since `getauxval` is not supported on macOS (but weak-linking does pass).
This PR defines the two symbols correctly and reduces calls to `getauxval` to linux.

c78b123982d59fe2d633659f23d6893de627f3f6 build: add -bind_at_load to hardened LDFLAGS (fanquake)
Pull request description:
This performs the same function as `-Wl,-z,now`, except for ld on macOS.
You can check the binaries using `otool -l`, and looking for the `LC_DYLD_INFO_ONLY` section; `lazy_bind_off` and `lazy_bind_size` should both be 0.
This seems to be the case with our current release binaries. However we can make the check, and applying the flag explicit in configure.
man ld:
```bash
-bind_at_load
Sets a bit in the mach header of the resulting binary which tells dyld
to bind all symbols when the binary is loaded, rather than lazily.
```

f7453dcc0386a4a1162ced1a490c096afa13178a build: remove linking librt for backwards compatibility (fanquake)
Pull request description:
Now that we require glibc 2.17+, see #17538, we can remove linking librt
for backwards compatibility purposes. The `clock_*` functions from librt
were merged into glibc as part of the [2.17 release](https://sourceware.org/ml/libc-announce/2012/msg00001.html):
* The `clock_*` suite of functions (declared in <time.h>) is now available
directly in the main C library. Previously it was necessary to link with
-lrt to use these functions. This change has the effect that a
single-threaded program that uses a function such as `clock_gettime' (and
is not linked with -lrt) will no longer implicitly load the pthreads
library at runtime and so will not suffer the overheads associated with
multi-thread support in other code such as the C++ runtime library.
Note that `librt` is already unused by the RISC-V and AARCH64 binaries as their librts don't export any `clock_*` functions. As an example, you can find a diff of the arm32 vs arm64 librt symbols [here](https://gist.github.com/fanquake/b08cb1f0d14df3133395d7796ebf030c).
Below is the library usage for the `v0.19.0.1` release (can delete these tables pre-merge).

Pull request description:
This is based off of #11622 and adds a deprecation warning when a BIP70 URL is used.
Rational:
- BIP70 increases attack surface in multiple ways and is difficult for third party wallets to implement in a secure manner
- Very few merchants use the standard BIP70 variant supported by Bitcoin Core
- The one major payment processor that doesn't support BIP21 and currently uses a customized non-standard version of BIP70 has indicated that "Unfortunately the original BIP70 is not useful for us."

895e6bbb2241e9175463734f3677398a9f38f0f8 build: if VERSION_BUILD is non-zero, include it in the package version (Andrew Chow)
Pull request description:
As noted on IRC, the filenames of the gitian build results do not contain the 4th digit of the version number if it has one, e.g. 0.17.0.1 produces files with the number 0.17.0. Furthermore, when RC's are built, the resulting filenames are of the release version and do not include `rc` in them. This occurs because `configure.ac` is written to create version numbers of the form `major.minor.rev` instead of `major.minor.rev.build` and without any rc version as it does not handle rc numbers.
This PR changes `configure.ac` to include the build number if it is greater than 0. It will also include the rc number if it is greater than 0. So the filenames of the gitian builds will now contain the full version number.
This behavior can be tested by setting `_CLIENT_VERSION_BUILD` and `_CLIENT_VERSION_RC` to non-zero values and then doing `make dist`. A tar file should be created with the correct versioning.

7abac98d3e3c1bc8ad66cb5c05184b9c5cc674d5 configure: Support -f{debug,macro}-prefix-map (Anthony Towns)
Pull request description:
When bitcoin is checked out in two directories (eg via git worktree) object files between the two will differ due to the full path being included in the debug section. `-fdebug-prefix-map` is used to replace this with "." to avoid this unnecessary difference and allow ccache to share objects between worktrees (provided the source and compile options are the same).
Also provide `-fmacro-prefix-map` if supported so that the working dir is not encoded in `__FILE__` macros.

ef3d4ce4c301caa57946f772f554678cd872fca8 build: call AC_PATH_TOOL for dsymutil in macOS cross-compile (fanquake)
Pull request description:
While testing #19530 I noticed that we couldn't call [`dsymutil`](https://www.llvm.org/docs/CommandGuide/dsymutil.html) after LTO:
```bash
../libtool: line 10643: x86_64-apple-darwin16-dsymutil: command not found
```
This updates configure to call `AC_PATH_TOOL` so that we end up with the
full path to dsymutil, similar to `otool` and `install_name_tool`, ie:
`/bitcoin/depends/x86_64-apple-darwin16/share/../native/bin/x86_64-apple-darwin16-dsymutil`.

0c63f808542ba02fc41aa90b1d96e9123f16d8ad build: Suppress -Wdeprecated-copy warnings (Hennadii Stepanov)
Pull request description:
Tomorrow, on Apr 23 the Ubuntu 20.04 release is expected. It packaged with Qt 5.12 LTS that has a nasty peculiarity to cause modern compilers, including Clang 10.0 and GCC 9.3, to emit spammy `-Wdeprecated-copy` warnings (#15822, #18419).
This PR suppress such warnings _temporarily_, until the [upstream is fixed](https://codereview.qt-project.org/c/qt/qtbase/+/272258).
Here are some affected systems (with system packages):
- Ubuntu 20.04 LTS + Qt 5.12.8 LTS + { Clang 10.0 | GCC 9.3 }
- Fedora 32 + Qt 5.13.2 + Clang 10.0
Reference: [QTBUG-75210](https://bugreports.qt.io/browse/QTBUG-75210)

ACK 0c63f808542ba02fc41aa90b1d96e9123f16d8ad seems fine to disable this warning for the 0.21.0 release temporarily and then enable it for 0.22.0, when boost is removed.
fanquake:
ACK 0c63f808542ba02fc41aa90b1d96e9123f16d8ad - I think it's ok to suppress these for now, given that `-Wdeprecated-copy` is enabled (via `-Wextra`) in GCC 9 and Clang 10. The Qt output is pretty noisy, and there's a few warnings from Boost as well.

a029805f57fa9a4ab9867c0d1e865675d57537c7 build: remove -Qunused-arguments workaround for clang + ccache (fanquake)
Pull request description:
This was added in 386efb7695 to address spammy Clang warnings when building with ccache.
The issue was addressed in [ccache 3.2](https://bugzilla.samba.org/show_bug.cgi?id=8118), and from a look at most major distros, it's only Debian Jessie that has a version of ccache older than that ([3.1](https://packages.debian.org/jessie/ccache)).
Therefore I think it's acceptable to drop this workaround, and re-enable warnings for unused driver arguments (when compiling using Clang and ccache).

4f4ae6f97e210fa0a2aa274bcd2a77a226fe6a7e build: set AC_PREREQ to 2.69 (fanquake)
Pull request description:
We use build macros such as `AX_CHECK_LINK_FLAG`, that require >=2.64, so our configure should also require Autoconf >= 2.64. The build would already blow up if 2.64 wasn't available. i.e:
```bash
configure.ac:320: error: Autoconf version 2.64 or higher is required
build-aux/m4/ax_check_link_flag.m4:74: AX_CHECK_LINK_FLAG is expanded from...
```
For reference, Autoconf 2.69 was released in [April of 2012](https://lists.gnu.org/archive/html/autoconf/2012-04/msg00041.html).

ddc7e42d600a0cb3e763cda0dc04a1f2f34e9440 build: Set minimum Automake version to 1.13 (Hennadii Stepanov)
Pull request description:
This PR suggests to set the required minimum Automake version to `1.13` explicitly for the following reasons:
- it guarantees that [CVE-2012-3386](https://lists.gnu.org/archive/html/automake/2012-07/msg00023.html) has been fixed
- `AC_CONFIG_MACRO_DIR` macro support, which we already use; from the [release notes](https://lists.gnu.org/archive/html/automake/2012-12/msg00038.html):
> Improvements to aclocal and related rebuilds rules:
> - Autoconf-provided macros AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS are now traced by aclocal, and can be used to declare the local m4 include directories. Formerly, one had to specify it with an explicit '-I' option to the 'aclocal' invocation.
- `AM_SILENT_RULES` macro support (since version `1.11`)
Automake `1.13` requires Autoconf `2.65` or greater. We already have `2.69` since #17769.
---
For reference, Automake `1.13` was released in [December of 2012](https://lists.gnu.org/archive/html/automake/2012-12/msg00038.html).
CentOS 7 uses Automake [`1.13.4`](https://centos.pkgs.org/7/centos-x86_64/automake-1.13.4-3.el7.noarch.rpm.html)

44f7a8d7a774f82417106c452d793e6f091bc23e Disable _FORTIFY_SOURCE when enable-debug (Andrew Chow)
Pull request description:
The `_FORTIFY_SOURCE` macro is enabled by default when hardening is enabled, but it requires optimization in order to be used. Since we disable all optimization with `--enable-debug`, this macro doesn't actually do anything and instead just causes a lot of warnings to be printed. This PR explicitly disables `_FORTIFY_SOURCE` so that these useless warnings aren't printed.

d6ac25bdd96589a71006e3ab3f303b091ffaa9e4 autoconf: Sane --enable-debug defaults. (Carl Dong)
Pull request description:
```
Don't optimize even if variables adhere to as-if rule. This is a
somewhat sane default for debugging.
```
-----
Fixes: #14830
This is more of a "do something dumb and have people correct you" kind of PR. The end goal is to have a configure flag that will allow for debugging without annoying "optimized out" messages, for developer experiences' sake. This is the minimal diff, but people have suggested `--enable-debug-slow` in the past.
