7c4f009195 [trivial] Rename feebumper variables according to project code style
Future PRs will completely refactor this translation unit and touch all
this code so we rename the variables to follow project stlye guidelines
in this preparation commit.

Don't use m_ prefixes for member variables since we're going to remove
the class entirely in the next commits.

Merge #10368: [wallet] Remove helper conversion operator from wallet
5a5e4e9 [wallet] Remove CTransaction&() helper conversion operator from wallet implementation. (Karl-Johan Alm)

Pull request description:

  The `CTransaction&()` operator in `CMerkleTx` makes conversion into `CTransaction`s transparent, but was marked as to-be-removed in favor of explicitly getting the `tx` ivar, presumably as the operator can lead to ambiguous behavior and makes the code harder to follow.

  This PR removes the operator and adapts callers. This includes some cases of `static_cast<CTransaction>(wtx)` → `*wtx.tx`, which is definitely an improvement.

Merge #11289: Add wallet backup text to import* and add* RPCs
c098c58 Wrap dumpwallet warning and note scripts aren't dumped (MeshCollider)
a38bfbc Add wallet backup text to import*, add* and dumpwallet RPCs (MeshCollider)

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/11243

  Adds "Requires a new wallet backup" text to `addwitnessaddress`, `importprivkey`, `importmulti`, `importaddress`, `importpubkey`, and `addmultisigaddress`. Also adds a warning to `dumpwallet` that backing up the seed alone is not sufficient to back up non-HD addresses

Merge #11590: [Wallet] always show help-line of wallet encryption calls
720d9e8fa [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)

Pull request description:

  We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
  In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.

  This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.

  IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.

  Fixes #11588

  Apologies for the mostly code move only PR. This is a pre-req for both #10740 and #10762

  All wallet component initialization/destruction functions are now in their own `wallet/init.cpp` translation unit and are no longer static functions on the CWallet class. The bitcoin_server also no longer has any knowledge that there are multiple wallets in vpwallet.

  There should be no changes in behavior from this PR.

47ba2c312 Fix currency/fee-rate unit string in the help text (Akio Nakamura)

Pull request description:

  1. The RPC help text should use the constant `CURRENCY_UNIT` defined in `policy/feerate.cpp` instead of the literal `'BTC'`.
    In the following 2 RPC commands, `'BTC'` is written directly in the help text.
    This commit changes them to use that constant.
       1) `estimatesmartfee`
       2) `estimaterawfee`

  2. Some RPC command use `'satoshis'` as the unit.

47ba2c312a Fix currency/fee-rate unit string in the help text
1. The RPC help text should use the constant CURRENCY_UNIT defined in
  policy/feerate.cpp instead of the literal 'BTC'. In the following
  2 RPC commands, 'BTC' is written directly in the help text.
    1) estimatesmartfee
    2) estimaterawfee
  And also, for these help strings, the notation
  'fee-per-kilobyte (in BTC)' is somewhat ambiguous.

  To write more precisely, this commit changes to 'fee rate in BTC/kB'
  with using the constant CURRENCY_UNIT.

2. Some RPC command use 'satoshis' as the unit. It should be written
  as 'satoshis' instead of 'Satoshis' in the RPC help text.

  So, this commit fixes this typo in getblocktemplate.

3. The phrase that '... feerate (BTC per KB) ...'  is used to explain
  the fee rate in the help text of following 2 RPC commands.
    1) getmempoolinfo
    2) fundrawtransaction
  But they are different from other similar help text of the RPCs.
  And also, 'KB' implies Kibibyte (2^10 byte).

  To unify and to clarify, this commit changes these phrase to
  '... fee rate in BTC/kB ...'.
  (BTC references the constant 'CURRENCY_UNIT')

ec6902d0ea rpc: Push down safe mode checks
This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.

This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.

e7fe320 MOVEONLY: Fee functions wallet/wallet.cpp -> wallet/fees.cpp (Russell Yanofsky)
d97fe20 Move some static functions out of wallet.h/cpp (Russell Yanofsky)

Pull request description:

  This just moves some static wallet fee and init functions out of `wallet/wallet.cpp` and into new `wallet/fees.cpp` and `wallet/init.cpp` source files. There is one commit updating declarations and callers, followed by two MOVEONLY commits actually moving the function bodies.

  This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization.

  Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

Pull request description:

  This is a followup to #10783.

  - The first commit doesn't change behavior at all, just simplifies code.
  - The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
  - The third commit updates developer notes after the cleanup.
  - The forth commit does some additional code cleanup in `getbalance`.

  Followup changes that should happen in future PRs:

  - [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
  - [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133

e067673f4e Avoid treating null RPC arguments different from missing arguments
This changes RPC methods to treat null arguments the same as missing arguments,
instead of throwing type errors. Specifically:

- `getbalance` method now returns the wallet balance when the `account` param
  is null instead of throwing a type error (same as when parameter is missing).
  It is still an error to supply `minconf` or `watchonly` options when the
  account is null.

- `addnode` and `setban` methods now return help text instead of type errors if
  `command` params are null (same as when params are missing).

- `sendrawtransaction`, `setaccount`, `movecmd`, `sendfrom`,
  `addmultisigaddress`, `listaccounts`, `lockunspent` methods accept null
  default values where missing values were previously allowed, and treat them
  the same.

90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)

Pull request description:

  Since C++11 the macro `NULL` may be:
  * an integer literal with value zero, or
  * a prvalue of type `std::nullptr_t`

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

  For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
  Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf

  With this patch applied there are no `NULL` macro usages left in the repo:

  ```
  $ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
  0
  ```

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
  * `0` → `nullptr` is handled in PR #10645 (manual)

Merge #9622: [rpc] listsinceblock should include lost transactions when parameter is a reorg'd block
876e92b Testing: listsinceblock should display all transactions that were affected since the given block, including transactions that were removed due to a reorg. (Karl-Johan Alm)
f999c46 listsinceblock: optionally find and list any transactions that were undone due to reorg when requesting a non-main chain block in a new 'removed' array. (Karl-Johan Alm)

Pull request description:

  The following scenario will not notify the caller of the fact `tx0` has been dropped:

  1. User 1 receives BTC in tx0 from utxo1 in block aa1.
  2. User 2 receives BTC in tx1 from utxo1 (same) in block bb1
  3. User 1 sees 2 confirmations at block aa3.
  4. Reorg into bb chain.
  5. User 1 asks `listsinceblock aa3` and does not see that tx0 is now invalidated.

  See `listsinceblock.py` commit for related test.

  The proposed fix is to iterate from the given block down to the fork point, and to check each transaction in the blocks against the wallet, in addition to including all transactions from the fork point to the active chain tip (the current behavior). Any transactions that were present will now also be listed in the `listsinceblock` output in a new `replaced` array. This operation may be a bit heavy but the circumstances (and perceived frequency of occurrence) warrant it, I believe.

  Example output:
  ```Python
  {
    'transactions': [],
    'replaced': [
      {
        'walletconflicts': [],
        'vout': 1,
        'account': '',
        'timereceived': 1485234857,
        'time': 1485234857,
        'amount': '1.00000000',
        'bip125-replaceable': 'unknown',
        'trusted': False,
        'category': 'receive',
        'txid': 'ce673859a30dee1d2ebdb3c05f2eea7b1da54baf68f93bb8bfe37c5f09ed22ff',
        'address': 'miqEt4kWp9zSizwGGuUWLAmxEcTW9bFUnQ',
        'label': '',
        'confirmations': -7
      }
    ],
    'lastblock': '7a388f27d09e3699102a4ebf81597d974fc4c72093eeaa02adffbbf7527f6715'
  }
  ```

  I believe this addresses the comment by @luke-jr in https://github.com/bitcoin/bitcoin/pull/9516#issuecomment-274190081 but I could be wrong..

9508761ed6 [wallet] [rpc] Add listwallets RPC
This commit adds a listwallets RPC, which lists the names of the
currently loaded wallets. This command intentionally shows no
information about the wallet other then the name. Information on
individual wallets can be obtained using the getwalletinfo RPC.

Merge #10783: [RPC] Various rpc argument fixes
4dc1915 check for null values in rpc args and handle appropriately (Gregory Sanders)
999ef20 importmulti options are optional (Gregory Sanders)
a70d025 fixup some rpc param counting for rpc help (Gregory Sanders)

Pull request description:

  Audited where named args will fail to use correct default values or may fail when additional optional arguments are added.

  Previously for these parameters, it was fine to omit them as positional arguments, but it would trigger UniValue runtime errors to set them to null, or to omit them while passing named parameters with greater positions (which would internally set earlier missing arguments to null). Now null values are treated the same as missing values so these errors do not occur.

  Included a few other small fixes while working on it.

  I didn't bother fixing account-based rpc calls.
