Merge #12572: [script] lint-whitespace: find errors more easily
0fbed98e42 [script] lint-whitespace: improve print linenumber (Akio Nakamura)

Pull request description:

  Before this PR, the linenumber infomaition is output if trailing-space or tab code was found, but the output occurence is only per a file.
  This PR separates the output timing of file name and line number.
  As a result, users will find where they need to fix more easily.

  example:

Merge #12567: util: Print timestamp strings in logs using ISO 8601 formatting
a7324bd79 Format timestamps using ISO 8601 formatting (e.g. "2018-02-28T12:34:56Z") (practicalswift)

Pull request description:

  Print timestamp strings in logs using [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) formatting (e.g. `2018-02-28T12:34:56Z`):
  * `Z` is the zone designator for the zero [UTC](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) offset.
  * `T` is the delimiter used to separate date and time.

  This makes it clear for the end-user that the date/time logged is specified in UTC and not in the local time zone.

b4bc32a451 [wallet] Get rid of CWalletTx default constructor
No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.

This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.

Pull request description:

Merge #11687: External wallet files
be8ab7d08 Create new wallet databases as directories rather than files (Russell Yanofsky)
26c06f24e Allow wallet files not in -walletdir directory (Russell Yanofsky)
d8a99f65e Allow wallet files in multiple directories (Russell Yanofsky)

Pull request description:

  This change consists of three commits:

  * The first commit is a pure refactoring that removes the restriction that two wallets can only be opened at the same time if they are contained in the same directory.
  * The second commit removes the restriction that `-wallet` filenames can only refer to files in the `-walletdir` directory.
  * The third commit makes second commit a little safer by changing bitcoin to create wallet databases as directories rather than files, so they can be safely backed up.

  All three commits should be straightforward:

  *  The first commit adds around 20 lines of new code and then updates a bunch of function signatures (generally updating them to take plain fs::path parameters, instead of combinations of strings, fs::paths, and objects like CDBEnv and CWalletDBWrapper).
  * The second commit removes two `-wallet` filename checks and adds some test cases to the multiwallet unit test.
  * The third commit just changes the mapping from specified wallet paths to bdb environment & data paths.

  **Note:** For anybody looking at this PR for the first time, I think you can skip the comments before _20 Nov_ and start reading at https://github.com/bitcoin/bitcoin/pull/11687#issuecomment-345625565. Comments before  _20 Nov_ were about an earlier version of the PR that didn't include the third commit, and then confusion from not seeing the first commit.

Pull request description:

  This PR contains some of the changes left as TODO in #11167 (and built on top of that PR). They are not intended for backporting.

  This removes the `CBase58`, `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey` classes, in favor of simple `Encode`/`Decode` functions. Furthermore, all Bitcoin-specific logic (addresses, WIF, BIP32) is moved to `key_io.{h,cpp}`, leaving `base58.{h,cpp}` as a pure utility that implements the base58 encoding/decoding logic.

Merge #12098: [scripts] lint-whitespace: add param to check last N commits
8dbf740f8 [scripts] lint-whitespace: check last N commits or unstaged changes (Sjors Provoost)

Pull request description:

  E.g. before you push three commits to Github and upset Travis, check if you didn't make any whitespace mistakes:
  ```sh
  contrib/devtools/lint-whitespace.sh 3
  ```

  This is slightly more convenient than doing:
  ```sh
  TRAVIS_COMMIT_RANGE=HEAD~3...HEAD contrib/devtools/lint-whitespace.sh
  ```

Give hint about gitian not able to download
Gitian fails to perform downloads right now on my set up. This can be circumvented by first checking out the tag being built and then doing the depends download step before running `gbuild`.

Merge #12097: [scripts] lint-whitespace: use perl instead of grep -P
40b17f5f9 [scripts] lint-whitespace: use perl instead of grep -P (Sjors Provoost)

Pull request description:

  MacOS does not support `grep -P` out of the box. This change makes
  it easier for developers to check for whitespace problems locally.

  Based on [this](https://stackoverflow.com/a/16658690) and [this](https://serverfault.com/a/504387) Stack Exchange answer.

  Tested with:
  ```sh
  export TRAVIS_COMMIT_RANGE='fe78c9a...62e0453'
  contrib/devtools/lint-whitespace.sh
  This diff appears to have added new lines with tab characters instead of spaces.

Merge #12479: RPC: Add child transactions to getrawmempool verbose output
1dfb4e7d7 [Tests] Check output of parent/child tx list from getrawmempool, getmempooldescendants, getmempoolancestors, and REST interface (Conor Scott)
fc44cb108 [RPC] Add list of child transactions to verbose output of getrawmempool (Conor Scott)

Pull request description:

  `bitcoin-cli getrawmempool true` only lists a transaction's parents in the `depends` field. This change adds a `spentby` field to the json response, which lists the transaction's children in the mempool.

  Currently the only way to find child transactions is to use `getrawmempool` or make another call to `getmempooldescendants` and search the response for transactions that list the parent_txid in the `depends` list, which is inefficient.

  This change allows direct lookup of children.

  Example Output
  ```
