0f09eb779d dummywallet: Reformat ignored wallet options list (Luke Dashjr)

Pull request description:

  When building w/o wallet support, we add all the wallet options as hidden options to avoid throwing errors/warnings that they're unknown.

  `-ignorepartialspends` is missing from this list. This PR adds it.

  (This seems like a good candidate for a linter? Or maybe we can autogenerate it?)

  Also reformats the dummywallet options list across multiple lines to make conflicts less often.

6ad372a97 wallet: log on rescan completion (andrewtoth)

Pull request description:

  Currently there is nothing logged when a rescan completes successfully. This leaves the last log message something like:
  ```
   Still rescanning. At block 573037. Progress=0.998415
  ```
  It is unclear when the rescan actually finished. This adds a `Rescan completed.` message to make it more clear.

Merge #15846: [POLICY] Make sending to future native witness outputs standard
c634b1e20 [POLICY] Make sending to future native witness outputs standard (Pieter Wuille)

Pull request description:

  As discussed in the April 18 2019 IRC meeting.

  This makes sending to future Segwit versions via native outputs (bech32) standard for relay, mempool acceptance, and mining. The reasons are:
  * This may interfere with smooth adoption of future segwit versions, if they're defined (by the sender wallet/node).
  * It violates BIP173 ("Version 0 witness addresses are always 42 or 62 characters, but implementations MUST allow the use of any version."), though admittedly this code was written before BIP173.
  * It doesn't protect much, as P2SH-embedded segwit cannot be filtered in this way.
  * As a general policy, the sender shouldn't care what the receiver likes his outputs to be.

  Note that _spending_ such outputs (including P2SH-embedded ones) remains nonstandard, as that is actually required for softfork safety.

Merge #14039: Disallow extended encoding for non-witness transactions
bb530efa18 Disallow extended encoding for non-witness transactions (Pieter Wuille)

Pull request description:

  BIP144 specifies that transactions without witness should use the legacy encoding, which is currently not enforced.

  This rule was present in the original SegWit implementation (https://github.com/bitcoin/bitcoin/pull/8149), but was subsequently dropped (https://github.com/bitcoin/bitcoin/pull/8589).

  As all hashes, txids, and weights are always computed over a reserialized version of a transaction, it is mostly harmless to permit extended encoding for non-segwit transactions, but I'd rather strictly follow the BIP.

Merge #14818: Bugfix: test/functional/rpc_psbt: Remove check for specific error message that depends on uncertain assumptions
c87fc71f7e Bugfix: test/functional/rpc_psbt: Correct test description comment (Luke Dashjr)
097c4aa379 Bugfix: test/functional/rpc_psbt: Remove check for specific error message that depends on uncertain assumptions (Luke Dashjr)

Pull request description:

  When converttopsbt is called with a signed transaction, it either fails with "TX decode failed" if one or more inputs were segwit, or "Inputs must not have scriptSigs and scriptWitnesses" otherwise.
  Since no effort is made by the test to ensure the inputs are segwit or not, avoid checking the exact message used.
  The error code is still checked to ensure it is of the correct kind of failure.
