Pull request description:
Writing tests should be straightforward and with little side-effects as possible.
I don't see how this is needed and can not be achieved with `self.num_nodes` (and `self.extra_args` et al.)

It seems we don't need a custom visitor pattern anymore to find what keys are affected by a script. Instead, infer the descriptor, and see which keys it expands to.

faead93c6c test: Make g_insecure_rand_ctx thread_local (MarcoFalke)
Pull request description:
Some tests might spin up several threads and `FastRandomContext` is not thread safe.
Fix that by giving each thread their own randomness context (as opposed to e.g. making `FastRandomContext` thread safe or add locks elsewhere).
Also, add the `g_` prefix to it (according to developer notes), since I am touching it anyway.

a46c8476e9 depends: disable unused qt features (fanquake)
73b46eeb7e depends: qt 5.9.7 (fanquake)
095e765975 depends: expat 2.2.6 (fanquake)
Pull request description:
This PR upgrades `expat` and `qt` in depends. The intention is to upgrade Qt in master to the latest point release of the current Qt LTS. This change can then be back-ported to the 0.17 branch (wether it makes it into 0.17.1 or not).
Then, sometime before the 0.18.0 release, we could move to using Qt 5.12+ in depends (which is also LTS). That discussion, as well as minimum supported Qt versions is in #13478.
### Qt 5.9.7
[Release announcement](https://blog.qt.io/blog/2018/10/23/qt-5-9-7-released/)
[Changelog](https://bugreports.qt.io/browse/QTBUG-70888?filter=20149)
### Expat 2.2.6
* Avoid doing arithmetic with NULL pointers in XML_GetBuffer
* Fix 2.2.5 regression with suspend-resume while parsing a document like <root/>
Full changelog [here](https://github.com/libexpat/libexpat/blob/R_2_2_6/expat/Changes)
a46c8476e9 disables a bunch of qt features we aren't currently using. This speeds up the qt depends build slightly (also decreases the size of the built `qt-5.9.7` tar by about 2%). The disabling is somewhat unintuitive, hence `[wip]` until after a travis run and gitian build.

Pull request description:
This improves a few minor issues with the RNG code:
* Avoid calling `GetRand*()` functions (which currently invoke OpenSSL, later may switch to using our own RNG pool) inside loops in addrman, networking code, `KnapsackSolver`, and `LimitOrphanSize`
* Fix a currently unreachable bug in `FastRandomContext::randbytes`.
* Make a number of simplifications to the unit tests' randomness code (some tests unnecessarily used their own RNG or the OpenSSL one, instead of using the unit test specific `insecure_rand_ctx`).
* As a precaution, make it illegal to copy a `FastRandomContext`.

dcb70b1522 Indicate -rpcauth option password hashing alg (Carl Dong)
Pull request description:
By indicating the password hashing algorithm, users of bitcoin distributions without the script in `share/rpcauth` and users who don't want to rely on said script can use alternative means to generate the password hash.
Question for reviewers: perhaps we should also indicate that it is specifically a HMAC-SHA-256 of the _**UTF-8**_ encoding of their password?

This introduces various changes to the importmulti logic:
* Instead of processing input and importing things at the same time, first
process all input data and verify it, so no changes are made in case of
an error.
* Verify that no superfluous information is provided (no keys or scripts
that don't contribute to solvability in particular).
* Add way more sanity checks, by means of descending into all involved
scripts.
8db0c3d42b Removed implicit CTransaction conversion from benchmaks (lucash-dev)
ed61abedb2 Removed implicit CTransaction constructor from tests (lucash-dev)
Pull request description:
This PR was split from #14906 and is a prerequisite for it.
It updates tests and benchmarks, removing all implicit calls to `CTransaction(CMutableTransaction&)` constructors. This will make possible making the constructor explicit in the next PR.
The original rationale for making the constructor explicit:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

Make lint/check-doc.py Python 3.4 compatible.
Also add .python-version for pyenv which will cause tests with too
modern syntax to fail on developer machine rather than on Travis.

6be0fb4b3 [refactor] Add a base DescriptorImpl with most common logic (Pieter Wuille)
Pull request description:
This patch modifies the internal `Descriptor` class to optionally construct and use an "expansion cache". Such a cache is a byte array that encodes all information necessary to expand a `Descriptor` a second time without access to private keys, and without the need to perform expensive BIP32 derivations. For all currently defined descriptors, the cache simply contains a concatenation of all public keys used.
This is motivated by the goal of importing a descriptor into the wallet and using it as a replacement for the keypool, where it would be impossible to expand descriptors if they use hardened derivation.
