This merge commit adds the following code from the github.com/decred/dcrutil package into a new github.com/decred/dcrd/dcrutil package: * Address handling * Amount type * AppDataDir func * bitflags functions * Block wrapper type * Hash160 func * Tx wrapper type * WIF type as well as all tests for this code. The old github.com/decred/dcrutil/hdkeychain package has also been merged and moved to github.com/decred/dcrd/dcrutil/hdkeychain. dcrd packages have been updated to use the new packages and the dep files have been updated for this change.

chaincfg
Package chaincfg defines chain configuration parameters for the three standard Decred networks and provides the ability for callers to define their own custom Decred networks.
Although this package was primarily written for dcrd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use parameters for the standard Decred networks or for projects needing to define their own network.
Sample Use
package main
import (
"flag"
"fmt"
"log"
"github.com/decred/dcrd/dcrutil"
"github.com/decred/dcrd/chaincfg"
)
var testnet = flag.Bool("testnet", false, "operate on the testnet Decred network")
// By default (without -testnet), use mainnet.
var chainParams = &chaincfg.MainNetParams
func main() {
flag.Parse()
// Modify active network parameters if operating on testnet.
if *testnet {
chainParams = &chaincfg.TestNetParams
}
// later...
// Create and print new payment address, specific to the active network.
pubKeyHash := make([]byte, 20)
addr, err := btcutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
if err != nil {
log.Fatal(err)
}
fmt.Println(addr)
}
