Merge #17578: rpc: simplify getaddressinfo labels, deprecate previous behavior
8925df86c4 doc: update release notes (Jon Atack)
8bb405bbad test: getaddressinfo labels purpose deprecation test (Jon Atack)
60aba1f2f1 rpc: simplify getaddressinfo labels, deprecate previous behavior (Jon Atack)
7851f14ccf rpc: incorporate review feedback from PR 17283 (Jon Atack)

Pull request description:

  This PR builds on #17283 (now merged) and is followed by #17585.

  It modifies the value returned by rpc getaddressinfo `labels` to an array of label name strings and deprecates the previous behavior of returning an array of JSON hash structures containing label `name` and address `purpose` key/value pairs.

  before
  ```
    "labels": [
      {
        "name": "DOUBLE SPEND",
        "purpose": "receive"
      }
  ```
  after
  ```
    "labels": [
      "DOUBLE SPEND"
    ]
  ```

  The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=labelspurpose`.

  For context, see:
  - https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001
  - http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-13.html#l-425 (lines 425-427)
  - http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622

  Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=labelspurpose` flag while verifying the rpc getaddressinfo help text and `labels` output.

  Next steps: deprecate the rpc getaddressinfo `label` field (EDIT: done in #17585) and add support for multiple labels per address. This PR will unblock those.

b77d5ad59f build: Disallow dynamic linking against c++ library (Wladimir J. van der Laan)

Pull request description:

  Closes: #17525. Taken over from #17531.

  Debian 8 (Jessie) has:
  - g++ version 4.9.2
  - libc version 2.19

  CentOS 7 has:
  - g++ version 4.8.5
  - libc version 2.17

  Ubuntu 16.04.4 (Xenial, oldest supported Ubuntu) has:
  - g++ version 5.3.1
  - libc version 2.23.0

  Taking the minimum of these as our target. According to [GNU ABI document](https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html) this corresponds to:

  - GCC 4.8.5: GCC_4.8.0
  - (glibc)    GLIBC_2_17

  This also contains a (long needed) commit to disallow dynamic linking to stdc++, as our releases statically link against that.

Merge #16669: build: use new fork of osslsigncode for windows gitian signing
feb5075777 build: use osslsigncode 2.0 in gitian (fanquake)

Pull request description:

  The original osslsigncode project, https://sourceforge.net/projects/osslsigncode, has been marked as abandonware:
  > This is now - and has been for a long while - abandonware. Feel free to create your own forks etc.".

  However, a fork has emerged, https://github.com/mtrojnar/osslsigncode, that has incorporated
  theuni's patches ([add the -pem option in extract-signature mode ](36715c1183) & [add the attach-signature command](3be7eb1676)) as well as updated the tool to work with OpenSSL 1.1 and other improvements.

  This commit switches the windows signer descriptor to use this new version of `osslsigncode`.

  I've tested using this new version of `osslsigncode` while doing a 0.18.1 gitian build, and it "seems" to work. However this needs a look over from Cory, to check if the tool is still compatible with his usage in the [`detached-sig-create.sh`](https://github.com/bitcoin/bitcoin/blob/master/contrib/windeploy/detached-sig-create.sh) script, as well as some review of the changes to `osslsigncode` itself. Hence WIP and chasing Concept ACKs / NACKs.

dce032ce29 Make IsTrusted scan parents recursively (Jeremy Rubin)

Pull request description:

  This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.

  This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.

  This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.

  The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.

          # Before `test_balance()`, we have had two nodes with a balance of 50
          # each and then we:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 60 from node B to node A with fee 0.01
          #
          # Then we check the balances:
          #
          # 1) As is
          # 2) With transaction 2 from above with 2x the fee
          #
          # Prior to #16766, in this situation, the node would immediately report
          # a balance of 30 on node B as unconfirmed and trusted.
          #
          # After #16766, we show that balance as unconfirmed.
          #
          # The balance is indeed "trusted" and "confirmed" insofar as removing
          # the mempool transactions would return at least that much money. But
          # the algorithm after #16766 marks it as unconfirmed because the 'taint'
          # tracking of transaction trust for summing balances doesn't consider
          # which inputs belong to a user. In this case, the change output in
          # question could be "destroyed" by replace the 1st transaction above.
          #
          # The post #16766 behavior is correct; we shouldn't be treating those
          # funds as confirmed. If you want to rely on that specific UTXO existing
          # which has given you that balance, you cannot, as a third party
          # spending the other input would destroy that unconfirmed.
          #
          # For example, if the test transactions were:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 10 from node B to node A with fee 0.01
          #
          # Then our node would report a confirmed balance of 40 + 50 - 10 = 80
          # BTC, which is more than would be available if transaction 1 were
          # replaced.

  The release notes have been updated to note the new behavior.

Merge #17285: doc: Bip70 removal follow-up
3ed8e3d079 doc: Remove explicit network name references (Fabian Jahr)
d6e493f0c2 wallet: Remove left-over BIP70 comment (Fabian Jahr)

Pull request description:

  A small follow-up to #17165 which removed BIP70 support.

  1. Removes one leftover mention of BIP70 in a comment.
  2. Removes BIP70 reference in comments on network/chain name strings. These can be removed as they are not really helpful and also incorrect: BIP70 only defines "main" and "test" but not "regtest". If/When signet gets merged we will add another name to the list that is not defined in BIP70. Mostly there is also an exhaustive list of the options included in the comment anyway.

  If we would like to keep an identifier for this naming scheme, I would suggest switching to something more generic, like 'short chain name'. Happy to implement that if that is preferred. Alternatively, we could add a reference to `CBaseChainParams`. That would also mean we don't have to change these lines again for signet.
