wallet: introduce -discardthreshold
Creates a wallet-specific, configurable dust limit that enables
gradual implementation of the dust limit. Each transaction created
with the wallet will adhere to this threshold rather than the dust
limits used for relay, so that the wallet stays usable while the
network changes (lowers) its dust limits.

This change only implements the parameter but does not change its
default value.
