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

056aba2b4f Remove fallbacks for boost_filesystem < v3
Minimum boost version was bumped to 1.47.0 in #8920, which
means the configure step won't even pass with older boost.

This version has boost filesystem v3, which means the
(crappy) fallbacks for older versions can go.

84f7ab08d2 Remove member variable hadNoDependencies from CTxMemPoolEntry
Fee estimation can just check its own mapMemPoolTxs to determine the same information.  Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.

b50cd7a67e Fix dangerous condition in ModifyNewCoins.
We were marking coins FRESH before being sure they were not overwriting dirty undo data. This condition was never reached in existing code because undo data was always flushed before UpdateCoins was called with new transactions, but could have been exposed in an otherwise safe refactor.
Clarify in the comments the assumptions made in ModifyNewCoins.
Add ability to undo transactions to UpdateCoins unit test.
Thanks to Russ Yanofsky for suggestion on how to make logic clearer and fixing up the ccoins_modify_new test cases.
