wallet RPC now uses wallet2::create_transactions and wallet2::commit_tx instead of wallet2::transfer. This made it possible to add the RPC call /transfer_split, which will split transactions automatically if they are too large. The old call to /transfer will return an error stating to use /transfer_split if multiple transactions are needed to fulfill the request.
