cf390dff89 build: silence gcc7's implicit fallthrough warning
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.

625488ace5 util: Work around (virtual) memory exhaustion on 32-bit w/ glibc
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.

e141aa4ba6 Add mallocinfo mode to getmemoryinfo RPC
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.

c459d509b7 build: Probe MSG_DONTWAIT in the same way as MSG_NOSIGNAL
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.

224e6eb089 util: Specific GetOSRandom for Linux/FreeBSD/OpenBSD
These are available in sandboxes without access to files or
devices. Also [they are safer and more straightforward](https://en.wikipedia.org/wiki/Entropy-supplying_system_calls)
to use than `/dev/urandom` as reading from a file has quite a few edge
cases:

- Linux: `getrandom(buf, buflen, 0)`. [getrandom(2)](http://man7.org/linux/man-pages/man2/getrandom.2.html)
  was introduced in version 3.17 of the Linux kernel.
- OpenBSD: `getentropy(buf, buflen)`. The [getentropy(2)](http://man.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/getentropy.2)
  function appeared in OpenBSD 5.6.
- FreeBSD and NetBSD: `sysctl(KERN_ARND)`. Not sure when this was added
  but it has existed for quite a while.

Alternatives:

- 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`.

Closes: #9676

This reverts commit caf6150e97.

getaddrinfo_a has a nasty tendency to segfault internally in its
background thread, on every version of glibc I tested, especially
under helgrind.

a92bf4af66 bitcoind: Daemonize using daemon(3)
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.

Original code by Matthew King, adapted by Wladimir van der Laan.
