Merge #13079: Fix rescanblockchain rpc to properly report progress
16be13345 Fix rescanblockchain rpc to property report progress (Ben Woosley)

Pull request description:

  Previously it assumed tip in all cases. This also extracts a RescanVerificationProgress helper object whose role is to manage reporting, in order to simplify ScanForWalletTransactions - more lines in total, but much simpler to follow the core logic.

Merge #13180: Fix re-declared scoped enum as unscoped (Causes issues with some compilers)
43f3dec00 Remove enum specifier (to avoid re-declare scoped enum as unscoped) (donaloconnor)

Pull request description:

  MSVC fails to compile with the changes made in #10742

  The problem is enum types were changed to scoped (`enum class`) but in some places `enum` as an unscoped is used.

  This is a very simple fix and I've tested it.

  Edit: Had to remove enum altogether - `enum class` doesn't compile on clang.

fad63eb [logging] Don't incorrectly log that REJECT messages are unknown. (John Newbery)

Pull request description:

  Reject messages are logged to debug.log if NET debug logging is enabled.

  Because of the way the `ProcessMessages()` function is structured,
  processing for REJECT messages will also drop through to the default
  branch and incorrectly log `Unknown command "reject" from peer-?`. Fix
  that by exiting from `ProcessMessages()` early.

a59dac3 refactor: Avoid extra lookups of mapAddressBook in listunspent RPC (João Barbosa)
d76962e rpc: Reduce cs_main lock in listunspent (João Barbosa)

Pull request description:

  On my system, where the wallet has 10000 unspents, the `cs_main` lock duration changed from 191ms to 36ms. The loop that generates the response takes around 155ms. So, the lock duration is reduced to around 20%.

Merge #12729: Get rid of ambiguous OutputType::NONE value
1e46d8a Get rid of ambiguous OutputType::NONE value (Russell Yanofsky)

Pull request description:

  Based on suggestion by @sipa https://github.com/bitcoin/bitcoin/pull/12119#issuecomment-357982763

  After #12119, the NONE output type was overloaded to refer to either an output type that couldn't be parsed, or to an automatic change output mode.  This change drops the NONE enum and uses a simple bool to indicate parse failure, and a new CHANGE_AUTO enum to refer the change output type.

  This change is almost a pure refactoring except it makes RPCs reject empty string ("") address types instead of treating them like they were unset. This simplifies the parsing code a little bit and could prevent RPC usage mistakes. It's noted in the release notes.

  Follows up #12408 by @MarcoFalke

  Followups for future PRs:

  - [ ] Add explicit support for specifying "auto" in `ParseOutputType` as suggested by promag and sipa: https://github.com/bitcoin/bitcoin/pull/12729#issuecomment-374799567 and https://github.com/bitcoin/bitcoin/pull/12729#discussion_r175969481

50b6533 scripted-diff: Rename SetBestChain callback ChainStateFlushed (Matt Corallo)

Pull request description:

  Previously, ChainStateFlushed would fire either if a full flush
  completed (which can happen due to memory limits, forced flush, or
  on its own DATABASE_WRITE_INTERVAL timer) *or* on a
  ChainStateFlushed-specific DATABASE_WRITE_INTERVAL timer. This is
  both less clear for clients (as there are no guarantees about a
  flush having actually happened prior to the call), and reults in
  extra flushes not clearly intended by the code. We drop the second
  case, providing a strong guarantee without removing the periodit
  timer-based flushing.

  This is a follow-up to discussion in #11857.

66dc662c8a Add compile time checking for all cs_KeyStore runtime locking assertions (practicalswift)

Pull request description:

  Add compile time checking for all `cs_KeyStore` runtime locking assertions.

  This PR is a subset of #12665. The PR was broken up to make reviewing easier.

  The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.

  Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
  first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
  * It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
  * It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

9cb6cdc59f Simplify semantics of ChainStateFlushed callback
Previously, ChainStateFlushed would fire either if a full flush
completed (which can happen due to memory limits, forced flush, or
on its own DATABASE_WRITE_INTERVAL timer) *or* on a
ChainStateFlushed-specific DATABASE_WRITE_INTERVAL timer. This is
both less clear for clients (as there are no guarantees about a
flush having actually happened prior to the call), and reults in
extra flushes not clearly intended by the code. We drop the second
case, providing a strong guarantee without removing the periodit
timer-based flushing.

Merge #13090: Remove Safe mode (achow101)
d8e9a2a Remove "rpc" category from GetWarnings (Wladimir J. van der Laan)
7da3b0a rpc: Move RPC_FORBIDDEN_BY_SAFE_MODE code to reserved section (Wladimir J. van der Laan)
2ae705d Remove Safe mode (Andrew Chow)

Pull request description:

  Rebase of #10563. Safe mode was [disabled by default and deprecated in 0.16](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.16.0.md#safe-mode-disabled-by-default), so probably should be removed for 0.17.

  > Rationale:
  >
  > Safe mode is useless. It only disables some RPC commands when large work forks are detected. Nothing else is affected by safe mode. It seems that very few people would be affected by safe mode. The people who use Core as a wallet are primarily using it through the GUI, which safe mode does not effect. In the GUI, transactions will still be made as normal; only a warning is displayed.
  >
  > I also don't think that we should be disabling RPC commands or any functionality in general. If we do, it should be done consistently, which safe mode is not. If we want to keep the idea of a safe mode around, I think that the current system needs to go first before a new system can be implemented.

d8e9a2ac74 Remove "rpc" category from GetWarnings
No longer used after removing safe mode.

This function can likely be simplified more, but I'll leave that
for later to make this easy to review.

7da3b0adb8 rpc: Move RPC_FORBIDDEN_BY_SAFE_MODE code to reserved section
Although this code is no longer ever sent back after removing safe mode,
it would be unwise to remove it from the header.

For one, it would be bad to accidentally re-use the number.

Also some API documentation / bindings are directly generated from the .h
file - this is why the "Aliases for backward compatibility" are there. We don't
want to break code that relies on this error code existing, even if it's never
generated.

So keep it around but move it to a reserved section.

Pull request description:

  Currently our wallet code will treat bare multisig outputs (meaning scriptPubKeys with multiple public keys + `OP_CHECKMULTISIG` operator in it) as ours without the user asking for it, as long as all private keys in it are in our wallet.

  This is a pointless feature. As it only works when all private keys are in one place, it's useless compared to single key outputs (P2PK, P2PKH, P2WPKH, P2SH-P2WPKH), and worse in terms of space, cost, UTXO size, and ability to test (due to lack of address format for them).

  Furthermore, they are problematic in that producing a list of all `scriptPubKeys` we accept is not tractable (it involves all combinations of all public keys that are ours). In further wallet changes I'd like to move to a model where all scriptPubKeys that are treated as ours are explicit, rather than defined by whatever keys we have. The current behavior of the wallet is very hard to model in such a design, so I'd like to get rid of it.

  I think there are two options:
  * Remove it entirely (do not ever accept bare multisig outputs as ours, unless watched)
  * Only accept bare multisig outputs in situations where the P2SH version of that output would also be acceptable

  This PR implements the first option. The second option was explored in #12874.
