Merge #16257: [wallet] abort when attempting to fund a transaction above -maxtxfee
806b0052c3b45415862f74f20ba5f389e5b673de [wallet] abort when attempting to fund a transaction above maxtxfee (Sjors Provoost)
Pull request description:
`FundTransaction` calls `GetMinimumFee` which, when the fee rate is absurdly high, quietly reduces the fee to `-maxtxfee`.
Becaue an absurdly high fee rate is usually the result of a fat finger, aborting seems safer behavior.
Before:
```
bitcoin-cli walletcreatefundedpsbt '[]' '[{"tb1q...": 0.01}]' 0 '{"feeRate": 10}' true
{
"psbt": "cHNidP8...gAA=",
"fee": 0.10000000,
"changepos": 1
}
```
After:
```
bitcoin-cli walletcreatefundedpsbt '[]' '[{"tb1q...": 0.01}]' 0 '{"feeRate": 10}' true
error code: -25
error message:
Fee exceeds maximum configured by -maxtxfee
```
QT still checks the max fee rate as expected:
