* Add GetUTXOsByBalances command to rpc * Fix wrong commands in GetBalanceByAddress * Moved calculation of TransactionMass out of TransactionValidator, so t that it can be used in kaspawallet * Allow CreateUnsignedTransaction to return multiple transactions * Start working on split * Implement maybeSplitTransactionInner * estimateMassIncreaseForSignatures should multiply by the number of inputs * Implement createSplitTransaction * Implement mergeTransactions * Broadcast all transaction, not only 1 * workaround missing UTXOEntry in partially signed transaction * Bugfix in broadcast loop * Add underscores in some constants * Make all nets RelayNonStdTxs: false * Change estimateMassIncreaseForSignatures to estimateMassAfterSignatures * Allow situations where merge transaction doesn't have enough funds to pay fees * Add comments * A few of renames * Handle missed errors * Fix clone of PubKeySignaturePair to properly clone nil signatures * Add sanity check to make sure originalTransaction has exactly two outputs * Re-use change address for splitAddress * Add one more utxo if the total amount is smaller then what we need to send due to fees * Fix off-by-1 error in splitTrasnaction * Add a comment to maybeAutoCompoundTransaction * Add comment on why we are increasing inputCountPerSplit * Add comment explaining while originalTransaction has 1 or 2 outputs * Move oneMoreUTXOForMergeTransaction to split_transaction.go * Allow to add multiple utxos to pay fee for mergeTransactions, if needed * calculate split input counts and sizes properly * Allow multiple transactions inside the create-unsigned-transaction -> sign -> broadcast workflow * Print the number of transaction which was sent, in case there were multiple * Rename broadcastConfig.Transaction(File) to Transactions(File) * Convert alreadySelectedUTXOs to a map * Fix a typo * Add comment explaining that we assume all inputs are the same * Revert over-refactor of rename of config.Transaction -> config.Transactions * Rename: inputPerSplitCount -> inputsPerSplitCount * Add comment for splitAndInputPerSplitCounts * Use createSplitTransaction to calculate the upper bound of mass for split transactions
