Daemon interactive mode is now working again.
RPC mapped calls in daemon and wallet have both had connection_context
removed as an argument as that argument was not being used anywhere.
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.
