Merge #14559: appveyor: Enable multiwallet tests
4dca7d0a98 appveyor: Enable multiwallet test (Chun Kuan Lee)

Pull request description:

  Based on #14320

  This PR enable multiwallet test on appveyor. Also re-enable symlink tests on Windows which is available after Windows Vista.

  I disable these tests in #13964 because I suppose that Windows does not support symlink, but I was wrong.

Merge #14320: [bugfix] wallet: Fix duplicate fileid detection
4ea77320c5 tests: add test case for loading copied wallet twice (Chun Kuan Lee)
2d796faf62 wallet: Fix duplicate fileid (Chun Kuan Lee)

Pull request description:

  The implementation in current master can not detect if the file ID is duplicate with flushed `BerkeleyEnvironment`. This PR would store the file ID in a global variable `g_fileids` and release it when the `BerkeleyDatabase` close. So it won't have to rely on a `Db*`.

  Fix #14304

Merge #14451: Add BIP70 deprecation warning and allow building GUI without BIP70 support

Pull request description:

  This is based off of #11622 and adds a deprecation warning when a BIP70 URL is used.

  Rational:

  - BIP70 increases attack surface in multiple ways and is difficult for third party wallets to implement in a secure manner
  - Very few merchants use the standard BIP70 variant supported by Bitcoin Core
  - The one major payment processor that doesn't support BIP21 and currently uses a customized non-standard version of BIP70 has indicated that "Unfortunately the original BIP70 is not useful for us."

ff37459abc Add tests for key origin support (Pieter Wuille)
2c6281f180 Add key origin support to descriptors (Pieter Wuille)

Pull request description:

  This adds support for [key origin](https://gist.github.com/sipa/e3d23d498c430bb601c5bca83523fa82#key-origin-identification) information to the descriptor parser, and exposes the resulting key path information through `FlatSigningProvider`.

  There is no observable functionality from this right now, except having the `scantxoutset` RPC accept descriptors that include key origin information.

  Longer term this feature helps with a potential descriptors-based walletless PSBT updater, or for importing hardware wallet xpubs (once the wallet can import descriptors).

Agreeing with @laanwj that this mention of the storage requirement could be removed, I did so and changed the wording accordingly.

Pull request description:

  Small change motivated by frustrations while writing `feature_block` tests; when a timeout is passed to `send_blocks_and_test` it isn't forwarded onto constituent waiting calls - you can end up waiting 60 seconds when you articulated e.g. 5. Respect the given timeout all the way down.

Merge #14011: Disable wallet and address book Qt tests on macOS minimal platform

  Stack trace from test crash: https://gist.github.com/ryanofsky/3401fb63c52d13d5585e7fc777361f1e
