Currently the only source for amount_asset is the value getter on a tx output, and we don't hand it too far around (mainly ignoring it if it isn't the chain's main currency). Eventually we could bubble them up to the wallet, use them to select outputs or actually support assets in the channels. Since we don't hand them around too widely I thought it was ok for them to be pass-by-value rather than having to allocate them and pass them around by reference. They're just 41 bytes currently so the overhead should be ok. Signed-off-by: Christian Decker <@cdecker>
