Merge #15226: Allow creating blank (empty) wallets (alternative) 
7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)

Pull request description:

  Alternative (kind of) to #14938

  This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.

  Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.

  Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".

  This is built on top of #15225 in order to fix GUI issues.

Miscellaneous RPC changes

  • The RPC createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HD seed. They cannot be opened in software older than 0.18. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 0.17.x. Encrypting a blank wallet will also set a HD seed for it.
