Pull request description:

  mac_alias and ds_store have moved from Bitbucket to GitHub.
  See https://github.com/al45tair/mac_alias and https://github.com/al45tair/ds_store.

  mac_alias has been updated to be compatible with Python 3? ~~~so we should be able to drop our patch.~~~ I've dropped some of the patch for now.

  Quickly tested on macOS, because depends building is broken with latest the Xcode see #11461.
  Related #8134.

Merge #10853: [tests] Fix RPC failure testing (again)
47ba8cf71 scripted-diff: rename assert_raises_jsonrpc to assert_raises_rpc error (John Newbery)
677d893ff [tests] do not allow assert_raises_message to be called with JSONRPCException (John Newbery)
5864e9c16 [tests] remove direct testing on JSONRPCException from individual test cases (John Newbery)

Pull request description:

  I did this a few months ago (here: #9707), but a few new examples have crept back in.

  When testing RPC failures, the test case should always assert the error value and message, to ensure that the failure was for the correct reason. Not doing that can hide bugs in the test code and mean that the test is not testing the correct behaviour.

  RPC failure testing should use the utility function `assert_raises_jsonrpc()` (renamed in the final commit of this PR to `assert_raises_rpc_error()`.

  This PR does the following:
  - changes all remaining instances of tests directly testing on `JSONRPCException` to calls to `assert_raises_jsonrpc()`
  - prevents `assert_raises_message()` from being called with `JSONRPCException`
  - scripted-diff changes `assert_raises_jsonrpc()` to `assert_raises_rpc_error()`

Pull request description:

  ```c++
  &vchRet[vchRet.size() - 4]

Merge #11437: [Docs] Update Windows build instructions for using WSL and Ubuntu 17.04
696ce46 [Docs] Update Windows build instructions for using WSL and Ubuntu 17.04 (fanquake)
4f890ba Add new step to clean $PATH var by removing /mnt specific Window's %PATH% paths that cause issues with the make system (Donal OConnor)

Pull request description:

  This updates the Windows build documentation with the workaround required to build using Ubuntu 17.04 on WSL, and makes it's explicit that building on Ubuntu 16.04 is broken, and not recommended.

  This includes a commit from @donaloconnor in #11244, and is mostly the investigative work of @laanwj throughout #8732, #8653 and quite a few other issues.

  I tested building on 14.04, 16.04.3 and 17.04 [here](https://github.com/bitcoin/bitcoin/pull/11244#issuecomment-327990251) and got the results we expect.

  Built master at c22a53cd63 on a Windows 10 VM (Version 1607, OS Build 14393.1593) using WSL with Ubuntu 14.04.

  Upgraded WSL to 16.04.3, and tried building c22a53cd63 using these instructions. The result is as expected.
  ![ubuntu 16 04 3](https://user-images.githubusercontent.com/863730/30235670-b9bf36bc-953d-11e7-8c1d-4debf7113032.png)

  Upgraded WSL to 17.04 and tried building 3255d6347b using these instructions.

  If someone else could also verify that builds are working on both 14.04 and 17.04 with these instructions, that would be great.

Merge #11406: Add state message print to AcceptBlock failure message.
6643b80 Add state message print to AcceptBlock failure message. (Matt Corallo)

Pull request description:

  This should make it easier to debug issues where the CheckBlock at
  the top of ProcessNewBlock fails (which does not print, in contrast
  to AcceptBlock, which always prints).

  This was motivated by #11371 which appears to be exactly such a case, and is not debuggable from the information provided. Not sure how much this would have helped in that case, but it is kinda weird that we can reject a block without ever printing why.

This fixes a bug in coverage logging that's been around since the logging was
introduced.

Merge #11419: Utils: Fix launchctl not being able to stop bitcoind
ab5bba778 Fix launchctl not being able to stop bitcoind (Alejandro Avilés)

Pull request description:

  `bitcoind` should not be launched as daemon from the Launch Agent. Otherwise, the process cannot be stopped from `launchctl stop`/`launchctl unload`.

  To reproduce the issue:

  ```console
  $ launchctl load ~/Library/LaunchAgents/org.bitcoin.bitcoind.plist
  $ pgrep -fla bitcoin
  60225 /usr/local/opt/bitcoin/bin/bitcoind
  $ launchctl unload ~/Library/LaunchAgents/org.bitcoin.bitcoind.plist
  ```

  Wait a few seconds and then run `pgrep` again:

  ```console
  $ pgrep -fla bitcoin
  60225 /usr/local/opt/bitcoin/bin/bitcoind
  ```

  The node is still running. This happens because Launch Agent is not supposed to run programs as daemons, since the agent makes sure they run in the background. Running them as daemons makes the Launch Agent lose control of the process and, so, it cannot be stopped.

ce2418fa4c [gui] reset addrProxy/addrSeparateProxyTor if colon char missing
If addrProxy or addrSeparateProxyTor do not have a colon in the string
somewhere in the QSettings storage, then attempting to open the options
dialog will cause the entire program to crash.

9f67646f17 Make AuthServiceProxy._batch method usable
Split off AuthServiceProxy.get_request method to make it easier to batch RPC
requests without duplicating code and remove leading underscore from _batch
method.

This does not change any existing behavior.

Merge #11433: qa: Restore bitcoin-util-test py2 compatibility
fafff1220 qa: Restore bitcoin-util-test py2 compatibility (MarcoFalke)

Pull request description:

  Currently `./configure && make check` will look for python3, then python2. As long as we support python2 (and use it as fallback), `make check` should run fine with both python2 and python3.

  Fixes #11352 by @Zenitur

e02007aade Limit AuthServiceProxyWrapper.__getattr__ wrapping
Change AuthServiceProxyWrapper.__getattr__ to only wrap proxied attributes, not
real attributes. This way AuthServiceProxyWrapper can continue logging RPC
calls without complicating other object usages, and special case handling for
the .url property can be dropped.

edafc718ad Fix uninitialized URI in batch RPC requests
This fixes "Wallet file not specified" errors when making batch wallet RPC
calls with more than one wallet loaded. This issue was reported by
NicolasDorier <nicolas.dorier@gmail.com>
https://github.com/bitcoin/bitcoin/issues/11257

Request URI is not used for anything except multiwallet request dispatching, so
this change has no other effects.

Fixes #11257

a2be3b66b5 [net] Ignore getheaders requests for very old side blocks
Sending a getheaders message with an empty locator and a stop hash
is a request for a single header by hash. The node will respond with
headers for blocks not in the main chain as well as those in the main
chain. To avoid fingerprinting, the node should, however, ignore
requests for headers on side branches that are too old.

Merge #11293: Deduplicate CMerkleBlock construction code, add test coverage
46ce223d1 Add tests for CMerkleBlock usage with txids specified (James O'Beirne)
5ab586f90 Consolidate CMerkleBlock constructor into a single method (James O'Beirne)

Pull request description:

  What started as a simple task to add test coverage ended up giving way to a light refactoring. This consolidates the mostly-identical `CMerkleBlock` constructors into one (using C++11 constructor delegation) and adds coverage for the by-txids construction case.
