172213be5b Add GetNewDestination to CWallet to fetch new destinations
Instead of having the same multiple lines of code everywhere
that new destinations are fetched, introduce GetNewDestination as
a member function of CWallet which does the key fetching, label
setting, script generation, and destination generation.

37a79a4fcc Move various SigningProviders to signingprovider.{cpp,h}
Moves all of the various SigningProviders out of sign.{cpp,h} and
keystore.{cpp,h}. As such, keystore.{cpp,h} is also removed.

Includes and the Makefile are updated to reflect this. Includes were largely
changed using:
git grep -l "keystore.h" | xargs sed -i -e 's;keystore.h;script/signingprovider.h;g'

50cede3f5a [mempool] Allow one extra single-ancestor transaction per package
This implements the proposed policy change from [1], which allows
certain classes of contract protocols involving revocation
punishments to use CPFP. Note that some such use-cases may still
want some form of one-deep package relay, though even this alone
may greatly simplify some lightning fee negotiation.

64fee48944 qt: Assert QMetaObject::invokeMethod result (João Barbosa)
f27bd96b5f gui: Fix missing qRegisterMetaType(WalletModel*) (João Barbosa)

Pull request description:

  Invalid/wrong dynamic calls aren't verified by the compiler. This PR asserts those dynamic calls. Once we bump Qt to at least 5.10 these can be refactored to use the `invokeMethod` overload that allows connecting to lambdas or member pointers, which are compile checked.

  For reference, one of the overloaded versions is https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-5.

Merge #16128: Delete error-prone CScript constructor only used with FindAndDelete
e1a55690e6 Delete error-prone CScript constructor (Gregory Sanders)

Pull request description:

  The behavior of this constructor is not the expected behavior compared to the other constructors which directly interpret the vector as a CScript, rather than serialize it into a new CScript. It has only four uses in the entire codebase. Delete this constructor and replace its four uses with the more clear serialization construction.

Pull request description:

  Make single parameter constructors `explicit` (C++11).

  Rationale from the developer notes:

  > - By default, declare single-argument constructors `explicit`.
  >   - *Rationale*: This is a precaution to avoid unintended conversions that might

613c46fe9e refactoring: move block metadata structures into BlockManager
Separate out the management of chain-agnostic block metadata from any given
CChainState instance. This allows us to avoid duplicating data like
`mapBlockIndex` unnecessarily for multiple chainstates.

This also adds a CChainState constructor that accepts and sets m_blockman.
Ultimately this reference will point to a BlockMan instance that
is shared across CChainStates.

3bf2b3a37b test: Split tool_wallet.py test into subtests (Jon Atack)
1eb13f09a9 test: Add log messages to test/functional/tool_wallet.py (Jon Atack)

Pull request description:

  This pull request adds test coverage in `test/functional/tool_wallet.py` to reproduce unexpected writes to the wallet as described in https://github.com/bitcoin/bitcoin/issues/15608 and serve as a benchmark for fixing the issue:

  - Wallet tool `info` unexpectedly writes to the wallet file if the wallet file permissions are read/write.

  - Wallet tool `info` raises with "Error loading . Is wallet being used by another process?" if the wallet file permissions are read-only.

  Goals:

  1. Reproduce the reported issue, define the current unexpected behavior, and add test coverage to guide a future fix. Add debug-level logging for sanity checking and commented-out assertions to be uncommented when fixing the issue. Add the same coverage to the wallet tool create test and the getwalletinfo test as regression tests while fixing the issue.

  2. Add info log messages as there are currently none in the test file.

  3. Split the tests out to separate functions as per review feedback.

  Thanks to Marco Falke for pointing me in the right direction.

e8fabd9253 build: prune dbus from depends (fanquake)

Pull request description:

  Since #8210 (59d063d076), we've been passing `-dbus-runtime` when configuring Qt.

  ```
  qtbase-opensource-src-5.9.7 $ ./configure -h | grep -i dbus
    -no-dbus ............. Do not build the Qt D-Bus module
    -dbus-linked ......... Build Qt D-Bus and link to libdbus-1 [auto]
    -dbus-runtime ........ Build Qt D-Bus and dynamically load libdbus-1 [no]
  ```

  This means we don't actually seem to be using the `D-Bus` we build in depends. This was pointed out by theuni at the time, [here](https://github.com/bitcoin/bitcoin/pull/7993#issuecomment-223114395) and [here](https://github.com/bitcoin/bitcoin/pull/8210#issuecomment-226930545), but was never followed up. dongcarl also bought it up as part of #16150.

  I've tested building and running `bitcoin-qt` using depends on Debian. Needs further testing.

test: Tool wallet test coverage for unexpected writes to wallet
This commit adds test coverage in `test/functional/tool_wallet.py` to reproduce unexpected writes to the wallet as described in https://github.com/bitcoin/bitcoin/issues/15608:

    - wallet tool `info` unexpectedly writes to the wallet file if the wallet file permissions are read/write.

    - wallet tool `info` raises with "Error loading . Is wallet being used by another process?" if the wallet file permissions are read-only.

1. Reproduce the reported issue, define the current unexpected behavior, and add test coverage to guide a future fix in the form of commented-out assertions to be uncommented when testing/fixing.

2. Provisionally extend the same coverage to the wallet tool create test and the getwalletinfo test as regression tests while fixing the issue.

3. Add some logging for sanity checking.

------

Changes after rebase:

5. Make wallet_path an instance method instead of a function in tool_wallet.py as per Marco Falke review suggestion.

6. Assert wallet permissions instead of logging them in tool_wallet.py. This ran into an issue with Appveyor keeping permissions at 666 so allowed for 666 as a workaround.

7. Change the added logging from info to debug level.

8. More helpful assertions order in tool_wallet.py#assert_tool_output. This change makes #assert_tool_output raise "Error loading wallet.dat. Is wallet being used by another process?" rather than a less-helpful message when debugging the read-only wallet permissions issue.
