Simple benchmarking framework
Benchmarking framework, loosely based on google's micro-benchmarking
library (https://github.com/google/benchmark)
Wny not use the Google Benchmark framework? Because adding Even More Dependencies
isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate
timings of threaded code then switching to the full-blown Google Benchmark library
should be considered.
The benchmark framework is hard-coded to run each benchmark for one wall-clock second,
and then spits out .csv-format timing information to stdout. It is left as an
exercise for later (or maybe never) to add command-line arguments to specify which
benchmark(s) to run, how long to run them for, how to format results, etc etc etc.
Again, see the Google Benchmark framework for where that might end up.
See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks
'sleep 100 milliseconds.'
To compile and run benchmarks:
cd src; make bench
Sample output:
Benchmark,count,min,max,average
Sleep100ms,10,0.101854,0.105059,0.103881

build: quiet annoying warnings without adding new ones
Disabling warnings can be tricky, because doing so can cause a different
compiler to create new warnings about unsupported disable flags. Also, some
warnings don't surface until they're paired with another warning (gcc). For
example, adding "-Wno-foo" won't cause any trouble, but if there's a legitimate
warning emitted, the "unknown option -Wno-foo" will show up as well.
Work around this in 2 ways:
1. When checking to see if -Wno-foo is supported, check for "-Wfoo" instead.
2. Enable -Werror while checking 1.
If "-Werror -Wfoo" compiles, "-Wno-foo" is almost guaranteed to be supported.
-Werror itself is also checked. If that fails to compile by itself, it likely
means that the user added a flag that adds a warning. In that case, -Werror
won't be used while checking, and the build may be extra noisy. The user would
need to fix the bad input flag.
Also, silence 2 more additional warnings that can show up post-c++11.

dnl Check for a flag to turn compiler warnings into errors. This is helpful for checks which may
dnl appear to succeed because by default they merely emit warnings when they fail.
dnl
dnl Note that this is not necessarily a check to see if -Werror is supported, but rather to see if
dnl a compile with -Werror can succeed. This is important because the compiler may already be
dnl warning about something unrelated, for example about some path issue. If that is the case,
dnl -Werror cannot be used because all of those warnings would be turned into errors.
build: quiet annoying warnings without adding new ones
Disabling warnings can be tricky, because doing so can cause a different
compiler to create new warnings about unsupported disable flags. Also, some
warnings don't surface until they're paired with another warning (gcc). For
example, adding "-Wno-foo" won't cause any trouble, but if there's a legitimate
warning emitted, the "unknown option -Wno-foo" will show up as well.
Work around this in 2 ways:
1. When checking to see if -Wno-foo is supported, check for "-Wfoo" instead.
2. Enable -Werror while checking 1.
If "-Werror -Wfoo" compiles, "-Wno-foo" is almost guaranteed to be supported.
-Werror itself is also checked. If that fails to compile by itself, it likely
means that the user added a flag that adds a warning. In that case, -Werror
won't be used while checking, and the build may be extra noisy. The user would
need to fix the bad input flag.
Also, silence 2 more additional warnings that can show up post-c++11.

5d4999951ee32e333b511245862628e80f83b703 prevector: Avoid unnamed struct, which is a GNU extension (DesWurstes)
Pull request description:
Since we [started using](https://github.com/bitcoin/bitcoin/pull/7165) the `ax_cxx_compile_stdcxx.m4` macro we've been passing `[noext]` to indicate that we don't want to use an extended mode, i.e GNU extensions. Speaking to Cory he clarified that the intention was to "require only vanilla c++11 and turn _off_ extension support so they would fail to compile".
However in the codebase we are currently making use of some GNU extensions. We should either remove there usage, or at least amend our CXX compiler checks. I'd prefer the former.
#### anonymous structs
```bash
./prevector.h:153:9: warning: anonymous structs are a GNU extension [-Wgnu-anonymous-struct]
struct {
```
This is fixed in https://github.com/bitcoin/bitcoin/commit/b849212c1ec01cc8633b8cdcd390da9b1051be0d.
#### variadic macros
```bash
./undo.h:57:50: warning: must specify at least one argument for '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]
::Unserialize(s, VARINT(nVersionDummy));
```
This is taken care of in #18087.
The `LOG_TIME_*` macros introduced in #16805 make use of a [GNU extension](https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html).
```bash

BCLog::Timer<std::chrono::seconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__)
^
6 warnings generated.
```
This is fixed in 081a0ab64eb442bc85c4d4a4d3bc2c8e97ac2a6d and 612e8e138b97fc5ad2f38847300132a8fc423c3f.
#### prevention
To ensure that usage doesn't creep back in we can add [`-Wgnu`](https://clang.llvm.org/docs/DiagnosticsReference.html#wgnu) to our compile time flags, which will make Clang warn whenever it encounters GNU extensions.
This would close #14130.
Also related to #17230, where it's suggested we use a GNU extension, the `gnu::pure` attribute.

build: quiet annoying warnings without adding new ones
Disabling warnings can be tricky, because doing so can cause a different
compiler to create new warnings about unsupported disable flags. Also, some
warnings don't surface until they're paired with another warning (gcc). For
example, adding "-Wno-foo" won't cause any trouble, but if there's a legitimate
warning emitted, the "unknown option -Wno-foo" will show up as well.
Work around this in 2 ways:
1. When checking to see if -Wno-foo is supported, check for "-Wfoo" instead.
2. Enable -Werror while checking 1.
If "-Werror -Wfoo" compiles, "-Wno-foo" is almost guaranteed to be supported.
-Werror itself is also checked. If that fails to compile by itself, it likely
means that the user added a flag that adds a warning. In that case, -Werror
won't be used while checking, and the build may be extra noisy. The user would
need to fix the bad input flag.
Also, silence 2 more additional warnings that can show up post-c++11.

Merge #19356: build: Fix search for brew-installed BDB 4 on OS X
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.

e9189a750b237eba1befc6b16c12c2cee3e0176c build: more robustly check for fcf-protection support (fanquake)
Pull request description:
When using Clang 7, we may end up trying to use the flag when it won't
work properly, which can lead to confusing errors. i.e:
```bash
/usr/bin/ld: error: ... <corrupt x86 feature size: 0x8>
```
Use `AX_CHECK_LINK_FLAG` & `--fatal-warnings` to ensure we wont use the flag in this case.
We do this as even when the error is emitted, compilation succeeds, and the binaries produced will run. This means we can't just check if the compiler accepts the flag, or if compilation succeeds (without or without `-Werror`, and/or passing `-Wl,--fatal-warnings`, which may not be passed through to the linker).
This was reported by someone configuring for fuzzing, on Debian 10, where Clang 7 is the default.
See here for a minimal example of the problematic behaviour:

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
..

1136: 5d pop %rbp

1132: 5d pop %rbp
1133: c3 retq
1134: 66 2e 0f 1f 84 00 00 nopw %cs:0x0(%rax,%rax,1)
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).

1bdbbbdc46c4e50bf07bc362e7e391ea1a53ea2f build: suppress array-bounds errors in libxkbcommon (fanquake)
Pull request description:
2 changes to better support building with GCC 12, which out of the box, is currently broken if you want to build using depends.
Prevent `-Warray-bounds` errors when building libxkbcommon. i.e:
```bash
src/xkbcomp/ast-build.c:82:27: error: array subscript 'ExprDef[0]' is partly outside array bounds of 'unsigned char[32]' [-Werror=array-bounds]
82 | expr->expr.value_type = type;
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~~
src/xkbcomp/ast-build.c:75:21: note: object of size 32 allocated by 'malloc'
75 | ExprDef *expr = malloc(size);
| ^~~~~~~~~~~~
```
It might be the case that these would be fixed by updating the
package, but that would also require installing new build tools (meson),
as well as potentially more dependencies (wayland), and it'd need
testing with Qt. For now, just turn the errors into wanrings.
Define `BOOST_NO_CXX98_FUNCTION_BASE` to prevent GCC warning about the use of `std::unary_function`. i.e:
```bash
/bitcoin/depends/aarch64-unknown-linux-gnu/include/boost/container_hash/hash.hpp:131:33:
warning: 'template<class _Arg, class _Result> struct std::unary_function' is deprecated [-Wdeprecated-declarations]
131 | struct hash_base : std::unary_function<T, std::size_t> {};
| ^~~~~~~~~~~~~~
In file included from /usr/include/c++/12/bits/unique_ptr.h:37,
from /usr/include/c++/12/memory:76,
from ./init.h:10,
from init.cpp:10:
/usr/include/c++/12/bits/stl_function.h:117:12: note: declared here
117 | struct unary_function
```
Boost `container_hash` (included via functional -> multi_index) uses
[`std::unary_function`, which was deprecated in C++11](https://en.cppreference.com/w/cpp/utility/functional/unary_function), and "removed" in
C++17. It's use causes warnings with newer compilers, i.e GCC 12.1.
Use the MACRO outlined in https://github.com/boostorg/container_hash/issues/22, and added to Boost Config for GCC 12 in https://github.com/boostorg/config/pull/430, to prevent it's use.
[BOOST_NO_CXX98_FUNCTION_BASE](https://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html):
> The standard library no longer supports std::unary_function and std::binary_function.
> They were deprecated in C++11 and is removed from C++14.

Simple benchmarking framework
Benchmarking framework, loosely based on google's micro-benchmarking
library (https://github.com/google/benchmark)
Wny not use the Google Benchmark framework? Because adding Even More Dependencies
isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate
timings of threaded code then switching to the full-blown Google Benchmark library
should be considered.
The benchmark framework is hard-coded to run each benchmark for one wall-clock second,
and then spits out .csv-format timing information to stdout. It is left as an
exercise for later (or maybe never) to add command-line arguments to specify which
benchmark(s) to run, how long to run them for, how to format results, etc etc etc.
Again, see the Google Benchmark framework for where that might end up.
See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks
'sleep 100 milliseconds.'
To compile and run benchmarks:
cd src; make bench
Sample output:
Benchmark,count,min,max,average
Sleep100ms,10,0.101854,0.105059,0.103881

dnl Until this is fixed upstream and we've synced, we'll just un-export them.
