68400d8b96 tests: Use explicit imports (practicalswift)
Pull request description:
Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.
Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.
An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Pull request description:
### qa: Close stdout and stderr file when node stops
Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.
Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)
### qa: Run gen_rpcauth with sys.executable
Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)
### qa: Use files for stdout/stderr to support Windows
It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.

https://github.com/bitcoin/bitcoin/pull/13715 introduced a new check
for _transport.is_closing() in mininode's P2PConnection's. This function
is only available from Python 3.4.4, though, while Bitcoin is supposed
to support all Python 3.4 versions.
In this change, we make the check conditional on is_closing() being
available. If it is not, then we revert to the behaviour before the
check was introduced; this means that
https://github.com/bitcoin/bitcoin/issues/13579 is not fixed for old
systems, but at least the tests work as they used to do before.
This includes a small refactoring from a one-line lambda to an
inline function, because this makes the code easier to read with more
and more conditions being added.
Fixes https://github.com/bitcoin/bitcoin/issues/13745.

Pull request description:
This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.
Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.
This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

d280617bf5 [qa] Add a test for merkle proof malleation (Suhas Daftuar)
ed82f17000 have verifytxoutproof check the number of txns in proof structure (Gregory Sanders)
Pull request description:
Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/
This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.
The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

`importprunedfunds` needs this check as well. Can expand it to cover this if people like the idea.

invocation of the disconnectnode rpc call. Handle this.

By default, libc will print fatal errors to /dev/tty instead of stderr.
Adding the LIBC_FATAL_STDERR_ to the environment variables allows
us to catch libc errors in stderr and test for them.

891beb0 [test] fundrawtransaction: lock watch-only shared address (Karl-Johan Alm)
Pull request description:
`self.nodes[0]` creates an address which is watch-only-shared with `self.nodes[3]`. If `nodes[0]` spends the associated UTXO during any of its sends later, the watchonly test will fail, as `nodes[3]` now has insufficient funds.
I ran into this in #12257 and this commit is in that PR as well, but I figured I'd split it out (and remove from there once/if merged).

Pull request description:
This removes the need to override the executable locations by just reading them from the config file. Beside making the code easier to read, running individual test on Windows is now possible by default (without providing further command line arguments).
Note: Of course, it is still possible to manually specify the location through the `BITCOIND` environment variable, e.g. `bitcoin-qt`.
