Merge #18082: logging: enable thread_local usage on macOS
d76894987d logging: enable thread_local usage on macOS (fanquake)

Pull request description:

  Now that we're building against a newer SDK (`10.14`), we should be able to enable `thread_local` usage on macOS. Have tested building and running locally, as well as cross-compiling and running the binaries on a macOS 10.14 system.

Pull request description:

  This updates leveldb to currently newest upstream commit 0c40829872:

  - CRC32C hardware acceleration is now an external library [crc32c](https://github.com/google/crc32c). This adds acceleration on ARM, and should be faster on x86 because of using prefetch. It also makes it easy to support similar instruction sets on other platforms in the future.
  - Thread handling uses C++11, instead of platform specific code.
  - Native windows environment was added. No need to maintain our own hacky one, anymore.
  - Upstream now builds using CMake. This doesn't mean we need to use that (phew), but internal configuration changed to a a series of checks, instead of OS profiles. This means the blanket error "Cannot build leveldb for $host. Please file a bug report' is removed.

  All changes: a53934a3ae...0c40829872

  Pretty much all our changes have been subsumed by upstream, so we figured it was cleaner to start over with a new branch from upstream with the still-relevant patches applied: https://github.com/bitcoin-core/leveldb/tree/bitcoin-fork-new

  There's quite some testing to be done (see below). See https://github.com/bitcoin-core/leveldb/issues/25 and https://github.com/bitcoin-core/leveldb/pull/26 for more history and context.

  TODO:
  - [x] Subtree `crc32c`
  - [x] Make linters happy about crc32 subtree
  - [x] Integrate `crc32c` library into build system
  - [x] MSVC build system

fanquake acd644b83d build: remove --large-address-aware linker flag
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 current
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

Merge #17738: build: remove linking librt for backwards compatibility
f7453dcc03 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).

fanquake 4f4ae6f97e build: set AC_PREREQ to 2.69
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:

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.

c78b123982 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.

fanquake bd44711e1b build: pass -dead_strip_dylibs to ld on macOS
This strips some unused dylibs from bitcoin-qt.

From man ld:
Remove dylibs that are unreachable by the entry point or exported symbols. 
That is, suppresses the generation of load command commands for dylibs 
which supplied no symbols during the link. This option should not be 
used when linking against a dylib which is required at runtime for 
some indirect reason such as the dylib has an important initializer.

b51bae1a5a doc: minor corrections in random.cpp (fanquake)

Pull request description:

  This introduces a new `randomenv` module that queries varies non-cryptographic (and non-RNG) sources of entropy available on the system; things like user IDs, system configuration, time, statistics, CPUID data.

  The idea is that these provide a fallback in scenarios where system entropy is somehow broken (note that if system entropy *fails* we will abort regardless; this is only meant to function as a last resort against undetected failure). It includes some data sources OpenSSL currently uses, and more.

  The separation between random and randomenv is a bit arbitrary, but I felt that all this "non-essential" functionality deserved to be separated from the core random module.

44f7a8d7a7 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.

instead produces a bunch of useless warnings. So explicitly disable
it when enable-debug so that those warnings are not produced.

  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.

Merge #15285: build: Prefer Python 3.4 even if newer versions are present on the system
0890339fb3 build: prefer python3.4 even if newer versions are present on the system (Sjors Provoost)

Pull request description:

  Python 3.4 is this mimimum supported version according to [doc/dependencies.md](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md)

  Systems with [PyEnv](https://github.com/pyenv/pyenv) ensure (via [.python-version](https://github.com/bitcoin/bitcoin/blob/master/.python-version)) that Python 3.4 is used
  for the functional tests. However `make check` calls `bitcoin-util-test.py`
  using the Python command found by `configure.ac`, which looks system wide.

  On systems with multiple versions of Python this would cause `make check`
  to fail, as it tries to call a version of Python that PyEnv blocks.

  This is solved by preferring python3.4 in `configure.ac`.

  I missed this in #14884, so ideally this should be tagged 0.18

3c3e31c3a4 [tests] Add wallet-tool test (João Barbosa)
49d2374acf [tools] Add wallet inspection and modification tool (Jonas Schnelli)

Pull request description:

  Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.

  Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.

  Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.

  * Using SSE4 (master, #10821): 4.6ms
  * Using 4-way SSE4 specialized for 64-byte inputs (#13191): 2.8ms
  * Using 8-way AVX2 specialized for 64-byte inputs (#13191): 2.1ms
  * Using 2-way SHA-NI specialized for 64-byte inputs (this PR): 0.56ms
