A new configuration flag -maxapsfee has been added, which sets the max allowed
avoid partial spends (APS) fee. It defaults to 0 (i.e. fee is the same with
and without APS). Setting it to -1 will disable APS, unless -avoidpartialspends
is set. (#14582)
The wallet will now avoid partial spends (APS) by default, if this does not result
in a difference in fees compared to the non-APS variant. The allowed fee threshold
can be adjusted using the new -maxapsfee configuration option. (#14582)
