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

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).

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.

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.

Since enable-debug disables optimization entirely, _FORTIFY_SOURCE
does nothing as it requires some kind of optimization enabled. It
instead produces a bunch of useless warnings. So explicitly disable
it when enable-debug so that those warnings are not produced.
Since libtool 1.5.2, on Linux libtool no longer sets RPATH for any
directories in the dynamic linker search path, so there is no longer an
issue.

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.

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.

When the build number (CLIENT_VERSION_BUILD) is non-zero, we want
to include that in the package version number so the resulting binaries
are named with the correct version.
This patch adds a --disable-bip70 configure option that disables BIP70
payment request support. When disabled, this removes the dependency of
the GUI on OpenSSL and Protobuf.

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.

bctest.py is only used as an import by bitcoin-util-test.py. There's no
value in keeping it as a separate module, so let's merge them into a
single module to keep building and packaging simpler.
bitcoin-test-util is importable as a module, so if any future modules
really want to import the code from bctest.py, they can import
bitcoin-test-util and call the bctest functions by name.
This is a well-intentioned but realistically annoying warning. Unfortunately,
it's too easy for a warning in one header to cause dozens of repeated warnings.
The functional tests and util tests both require a config file that is
generated by ./configure. This commit merges those two config
files into a single configuration file that can be shared by both tests.
The config from config.ini is put into a Namespace object to maintain
the interface with bctest.py. A future commit could change this
interface to use a dictionary instead of a namespace.
glibc-specific: On 32-bit systems set the number of arenas to 1. By
default, since glibc 2.10, the C library will create up to two heap
arenas per core. This is known to cause excessive virtual address space
usage in our usage. Work around it by setting the maximum number of
arenas to 1.
This adds a mode argument to `getmemoryinfo`. By default the output
will remain the same. However if a mode argument of `mallocinfo` is
provided the result of glibc `malloc_info` (if available) will
be returned as a string, as-is.
This is useful for tracking heap usage over time or troubleshooting
memory fragmentation issues.
Instead of the WIN32-specific workaround, detect lack of `MSG_DONTWAIT`
in the build system. This allows other platforms without `MSG_DONTWAIT`
to work too.

- Linux has sysctl `CTL_KERN` / `KERN_RANDOM` / `RANDOM_UUID`
which gives 16 bytes of randomness. This may be available
on older kernels, however [sysctl is deprecated on Linux](https://lwn.net/Articles/605392/)
and even removed in some distros so we shouldn't use it.
Add tests for `GetOSRand()`:
- Test that no error happens (otherwise `RandFailure()` which aborts)
- Test that all 32 bytes are overwritten (initialize with zeros, try multiple times)
Discussion:
- When to use these? Currently they are always used when available.
Another option would be to use them only when `/dev/urandom` is not
available. But this would mean these code paths receive less testing,
and I'm not sure there is any reason to prefer `/dev/urandom`.

OBJCXX's std flags don't get defined by our cxx macro. Rather than hard-coding
to c++11, just force OBJCXX to be the same as CXX unless the user specified
otherwise.
Simplified version of #8278. Assumes that every OS that (a) is supported
by Bitcoin Core (b) supports daemonization has the `daemon()` function
in its C library.
- Removes the fallback path for operating systems that support
daemonization but not `daemon()`. This prevents never-exercised code from
ending up in the repository (see discussion here:
https://github.com/bitcoin/bitcoin/pull/8278#issuecomment-242704745).
- Removes the windows-specific path. Windows doesn't support `daemon()`,
so it don't support daemonization there, automatically.

- LevelDB platform was not guessed correctly (it ended up defining
`-DOS_OPENBSD59` instead of `-DOS_OPENBSD`)
- On OpenBSD there is no convenience link from `python3.5` to `python3`:
add detection for other python interpreter names.
- If it has to guess the LevelDB OS, print a autoconf warning so that
the user can check.
