…, and fix OpenBSD 6.2 build

1d4cbd2 test: Add unit test for LockDirectory (Wladimir J. van der Laan)
fc888bf util: Fix multiple use of LockDirectory (Wladimir J. van der Laan)

Pull request description:

  Wrap the `boost::interprocess::file_lock` in a `std::unique_ptr` inside the map that keeps track of per-directory locks.

  This fixes a build issue with the clang 4.0.0+boost-1.58.0p8 version combo on OpenBSD 6.2, and should have no effect otherwise.

  Also add a unit test, make the function thread-safe, and fix Linux versus Windows behavior inconsistency.

  Meant to fix bitcoin#12413.

40c5886 Fix illegal default `addProxy` and `addrSeparateProxyTor` settings. (251)

Pull request description:

  In f05d349 the value of the `addrProxy` and `addrSeparateProxyTor` settings is set to an illegal default value, because the value of `DEFAULT_GUI_PROXY_PORT ` is passed to the `fieldWidth` parameter of the `QString QString::arg(const QString &a, int fieldWidth = 0, QChar fillChar = QLatin1Char( ' ' )) const` method:

  https://github.com/bitcoin/bitcoin/blob/29fad97c320c892ab6a480c81e2078ec22ab354b/src/qt/optionsmodel.cpp#L139

  This will create a default proxy setting that consists of 9053 characters and ends with the string `127.0.0.1:%2`.

  This PR attempts to resolve bitcoin#12623 by setting the correct value for the `addrProxy` and `addrSeparateProxyTor` settings (i) if the proxy setting does not exist; or (ii) if the proxy setting has an illegal value caused by to the aforementioned bug.

  The second condition is *only* relevant if we don't want Bitcoin Core 0.16.0 users to explicitly reset their settings to see the correct default proxy port value.

…aller ends.

7d8a8cc Avoid launching as admin when NSIS installer ends. (JeremyRand)

Pull request description:

  The Bitcoin Core NSIS script runs with elevated privileges.  Unfortunately, this means that it launches Bitcoin Core itself with elevated privileges when the user chooses to launch Bitcoin Core at the end of the installation procedure.  This PR works around the issue by having `explorer.exe` launch Bitcoin Core.  Seems to be a similar approach to what http://nsis.sourceforge.net/ShellExecAsUser_plug-in does, but without a plugin.

  I've tested this with Sysinternals Process Explorer on Windows 10 32-bit.  I wouldn't expect any differences in behavior on other Windows releases, but if anyone would like to test on other Windows releases, feel free.

  h/t to "UK" at https://mdb-blog.blogspot.se/2013/01/nsis-lunch-program-as-user-from-uac.html?showComment=1410158039989#c2463780017054126736 for the sample code.

  Fixes bitcoin#7990.

…ompat w/o config

150b2f0 Default to defining endian-conversion DECLs in compat w/o config (Matt Corallo)

Pull request description:

  While this isn't a supported build configuration, some build
  systems need to build without going through our autotools steps,
  so defaulting to something sane may make it easier to build.

  Specifically, this fixes the inability to build
  rust-bitcoinconsensus on some non-x86 platforms. It needs to build
  without our autotools/configure steps to ensure correct compile
  args are passed from the rust build system to gcc. Converting the
  args from the rust build system to gcc would be a lot of
  unmaintainable work.

Pull request description:

  Several tests call disconnect_nodes() on each node-pair in rapid
  succession, resulting in a race condition if a node disconnects a peer
  in-between the calculation of the nodeid's to disconnect and the
  invocation of the disconnectnode rpc call.  Handle this.

…nt counts

f30e9be RPC Docs: gettxout*: clarify bestblock and unspent counts (David A. Harding)

Pull request description:

  Expounds on two things I've seen confuse inexperienced users:

  - transactions/outputs in `gettxoutsetinfo`: a user thought this was the total number of transactions or outputs ever seen on the chain, whereas it's only the number in the UTXO.

  - bestblock in `gettxout`: a user thought this was the block that included the output, not realizing it was the tip of the current best block chain.  I also copied this text to `gettxoutsetinfo` for congruency.  I skimmed other uses of "bestblock" in the RPC docs and they seemed clear to me.
