Pull request description:

  The args have been deprecated since 0.17 (maybe longer) and since we reject unknown args, there is no need to add deprecated args to the list of hidden args and then hand-craft an error message if a user provides them.

Merge #13152: [rpc] Add getnodeaddresses RPC command
a2eb6f5405 [rpc] Add getnodeaddresses RPC command (chris-belcher)

Pull request description:

  Implements issue https://github.com/bitcoin/bitcoin/issues/9463

  New getnodeaddresses call gives access via RPC to the peers known by the node. It may be useful for bitcoin wallets to broadcast their transactions over tor for improved privacy without using the centralized DNS seeds. getnodeaddresses is very similar to the getaddr p2p method.

  Please advise me on the best approach for writing an automated test. By my reading the getaddr p2p method also isn't really tested.

New getnodeaddresses call gives access via RPC to the peers known by
the node. It may be useful for bitcoin wallets to broadcast their
transactions over tor for improved privacy without using the
centralized DNS seeds. getnodeaddresses is very similar to the getaddr
p2p method.

Tests the new rpc call by feeding IP address to a test node via the p2p
protocol, then obtaining someone of those addresses with
getnodeaddresses and checking that they are a subset.

Merge #14236: qa: generate --> generatetoaddress change to allow tests run without wallet
0ca4c8b3c6 Changed functional tests which do not require wallets to run without (sanket1729)

Pull request description:

  Addresses #14216 . Changed Changed `get_deterministic_priv_key()` to return named tuple`(address, key)`
  I have tried to be exhaustive as possible in maximum coverage for non-wallet mode without affecting any coverage for wallet mode.

  However, I could not check the tests in wallet mode because of timeout issues. Hopefully, travis job checks those.

  Tests `feature_block.py`, `feature_logging.py` and `feature_reindex.py` were skipping despite having no direct dependency on any wallet functions. So, I have also disabled the `skip_test_no_wallet()` for those files too.

Merge #13578: [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions
f1bd03eb01 [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions (mruddy)

Pull request description:

  Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5.

  This PR Follows the lead of https://github.com/bitcoin/bitcoin/pull/11986.

  I upgraded both patch files to correspond to the version `4.2.5` libzmq files.
  I assume doing so is still necessary and correct.

  Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.:
  ```
  /bitcoin/depends> make zeromq
  Extracting zeromq...
  /bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK
  Preprocessing zeromq...
  patching file src/windows.hpp
  Hunk #1 succeeded at 58 (offset 3 lines).
  patching file src/thread.cpp
  Hunk #1 succeeded at 307 with fuzz 2 (offset 87 lines).
  Hunk #2 succeeded at 323 with fuzz 2 (offset 90 lines).
  ```
  Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.

  More info: https://github.com/zeromq/libzmq/releases/tag/v4.2.5

Merge #14227: integer division instead of implicit double conversion
be54f42e5f use integer division instead of double conversion and multiplication for computing amounts (Arvid Norberg)

Pull request description:

  use integer division instead of double conversion and multiplication for computing amounts. This will most likely generate identical code.

  My main argument in favour of this change is one of purity, that we should not rely on implicit conversion from `CAmount` -> `double` and back again. Today this implicit conversion can happen because `CAmount` is just a typedef to `int64_t`. However, I envision a future where `CAmount` is a proper type that does not allow suspicious implicit conversions like these.

5d296ac810 Add function to close all Db's and reload the databae environment (Andrew Chow)
a769461d5e Move BerkeleyEnvironment deletion from internal method to callsite (Andrew Chow)

Pull request description:

  This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).

  Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.

  To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).

  As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

e413c2ddd1 qa: Fix codespell error and have lint-spelling error instead of warn (MarcoFalke)

Pull request description:

  Currently the functional tests require the wallet module to be compiled into the Bitcoin Core executable. For example the premine (or datadir cache) to speed up tests when run in parallel would mine a bunch of blocks and store the private keys to sign the coinbase tx outputs in a wallet. There is no need to have the overhead of the whole wallet module by using keys that are deterministic for all runs.

  Note that this change most likely requires the `./test/cache/` to be cleared.

Pull request description:

  The second commit in #13439 made the `TODO` in the first commit impossible to solve.

  The meaning of `fNewBlock` changed from "This is the first time we process this block" to "We are about to write the new *valid* block".

  So whenever `fNewBlock` is true, the block was valid. And whenever the `fNewBlock` is false, the block is either valid or invalid. If it was valid and not new, we know it is a `"duplicate"`. In all other cases, the `BIP22ValidationResult()` will return the reason why it is invalid.

  I don't understand why `-help-debug` would be useful without requesting the help, and I've made this particular mistake one time too many.

9a565a8282 Pass export privkey DER compression flag correctly
By passing a bitfield where a boolean was expected, the result was
always compressed. Fix this.

Merge #14209: logging: Replace LogPrint macros with regular functions
fae3fbd61a logging: Replace LogPrint macros with regular functions (MarcoFalke)

Pull request description:

  It is not possible to run the full test suite when configured with `--enable-lcov`, since logging is disabled currently so that "unnecessary branches are not analyzed". (See c8914b9dbb)

  Fix this instead by replacing the macros with functions.

d0b1cee1fe doc: -help-debug implies -help
I don't understand why `-help-debug` would be useful without requesting
the help, and I've made this particular mistake one time too many.

(ok, so apparently the original reason that -help-debug is an option is
to show debug options in the GUI option overview? that seems very
unlikely to ever be used, if someone wants to add a way to show debug
options in the GUI it'd be better to have a check box)

Pull request description:

  Move interfaces/* from libbitcoin_util to libbitcoin_server.

  Usage of these is shared between `bitcoind` and `bitcoin-qt`. It is unnecessary for them to be linked against the other utilities. Also semantically they belong with the server/node, I think.
