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?

Pull request description:

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.

24d3a7b3a [refactor] Use DescriptorImpl internally, permitting access to new methods (Pieter Wuille)
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.

Pull request description:
https://github.com/bitcoin/bitcoin/pull/14565 needs test coverage. This PR refactors wallet_importmulti.py to the following pattern:
1. Add `get_key()` and `get_multisig()` methods, which generate keys on node0 and return the priv/pubkeys and all scriptPubKey and address variants.
2. Add `test_importmulti()` method, which takes an importmulti request, sends it to node1 and tests against success and error codes/messages.
3. Add `test_address()` method, which takes an address, sends it as a getaddressinfo request to node1 and tests the values returned.
This does not add any specific testing for #14565, but makes it very straightforward to add that testing: `test_importmulti()` can be easily updated to test for returned warnings, and `test_address()` can be called multiple times against the different address variants for a singlesig/multisig.

522b80b33f add `--retry 5` to curl opts in install_db4.sh (qubenix)
Pull request description:
I ran into some network issue that caused the clang patch to not download and the script exited. A retry would have solved it. The fallback choice, `wget`, has a default 20 retries.
I chose 5 retries because `curl` backs of after each try, starting at one second and doubling each time. 5 retries means that worst case scenario would be a total of 31 seconds waiting between attempts. IMO that should be enough tries if internet is working, but not too much if internet is not working.

Calling getblocktemplate without the segwit rule specified is most
likely a client error, since it results in lower fees for the miner.
Prevent this client error by failing getblocktemplate if called without
the segwit rule specified.
