d92204c900 build: add warning to detect hidden copies in range-for loops (Cory Fields)
466e16e0e8 cleanup: avoid hidden copies in range-for loops (Cory Fields)
Pull request description:
Following-up on #13241, which was itself a follow-up of #12169.
See title. Fixing these would otherwise be a continuous process, adding the warning should keep them from cropping up.
Note that the warning seems to be Clang-only for now.

0df017889b Benchmark Merkle root computation (Pieter Wuille)
Pull request description:
This introduces a framework for specialized double-SHA256 with 64 byte inputs. 4 different implementations are provided:
* Generic C++ (reusing the normal SHA256 code)
* Specialized C++ for 64-byte inputs, but no special instructions
* 4-way using SSE4.1 intrinsics
* 8-way using AVX2 intrinsics
On my own system (AVX2 capable), I get these benchmarks for computing the Merkle root of 9001 leaves (supported lengths / special instructions / parallellism):
* 7.2 ms with varsize/naive/1way (master, non-SSE4 hardware)
* 5.8 ms with size64/naive/1way (this PR, non-SSE4 capable systems)
* 4.8 ms with varsize/SSE4/1way (master, SSE4 hardware)
* 2.9 ms with size64/SSE4/4way (this PR, SSE4 hardware)
* 1.1 ms with size64/AVX2/8way (this PR, AVX2 hardware)

9e49db2 Make --enable-debug to pick better options (Evan Klitzke)
Pull request description:
Cherry-picked (and rebased) 94189645e67f364c4445d62e2b00c282d885cbbf from the "up for grabs" PR: "[build] Make --enable-debug pick better options" (#12695).
See previous review in #12695.

Various changes:
* Don't check $GCC and $GXX
* Prefer -Og instead of -O0
* If -g3 isn't available, use -g
This also incidentally fixes compiler warnings with GCC and glibc when using
--enable-debug, as the old default values mixed poorly with the hardening flags.
This PR solves #12867 (needs to run autogen.sh && ./configure)
clang (Apple LLVM version 9.1.0 (clang-902.0.39.1)) warns unused
argument '-pie' during compilation.
So we check for warnings in the test using $CXXFLAG_WERROR.
Windows is alse default-pie and was special-cased because it also
warned, but we can also eliminate that case if warnings are caught.
It is redundant to check for the presence of MSG_NOSIGNAL macro in
configure.ac, define HAVE_MSG_NOSIGNAL and then check whether the later
is defined in the source code. Instead we can check directly whether
MSG_NOSIGNAL is defined. Same for MSG_DONTWAIT.
In addition to that, the checks we had in configure.ac produce a
compiler warning about unused variable and thus could fail if
-Werror is present and erroneously proclaim that the macros are
not available.
8172d3a configure: UniValue 1.0.4 is required for pushKV(, bool) (Luke Dashjr)
Pull request description:
The breaking changes (#12193) are already merged, so this blocks 0.17.0.
It depends on jgarzik/univalue#42 or jgarzik/univalue#50 being merged and released in UniValue 1.0.4.

912da1dcc Use AC_ARG_VAR to set ARFLAGS. (René Nyffenegger)
Pull request description:
Override the default of ARFLAGS of `cru` to `cr`.
When building, ar produces a warning for each archive, for example
```
AR libbitcoin_server.a
/usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')
```
Since `u` is the default anyway, it cannot hurt to remove it.
