Wallet changes
--------------
When creating a transaction with a fee above `-maxtxfee` (default 0.1 BTC),
the RPC commands `walletcreatefundedpsbt` and  `fundrawtransaction` will now fail
instead of rounding down the fee. Beware that the `feeRate` argument is specified
in BTC per kilobyte, not satoshi per byte.
[wallet] abort when attempting to fund a transaction above maxtxfee FundTransaction calls GetMinimumFee which, when the fee rate is absurdly high, quietly reduced the fee to -maxtxfee. Becaue an absurdly high fee rate is usually the result of a fat finger, aborting seems safer behavior. 2019-06-28 22:44:38 -04:00			`Wallet changes`
