Pull request description:

  based on top of
  - [x] #1662

  This introduces a new wallet function, `CWallet::FundTransaction()` (and exposes it via RPC with `fundrawtransaction`), to fill a tx containing only vouts (or not enough vins to cover the vouts) with unspent coins from the wallet.

  `fundrawtransaction` will not modify existing inputs, and will add one change output (if needed) to the outputs. It will not sign the inputs (so can include also watch-only or multi-sig inputs, if enabled).

  adapting the tests for the (more recent) framework.

  [`*`] Note: this has been included to be able to call `fundrawtransaction` without the need for an unencrypted wallet (for the change address key)

…bt also lock manually selected coins

6d1f513 [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)

Pull request description:

  When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.

  Note that when  creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.

  See bitcoin#7518 for historical background.
