Dave Collins 3942a116e4 docs: Make various README.md files consistent.

First, it removes the documentation section from all the README.md files
and instead puts a web-based godoc badge and link at the top with the
other badges.  This is being done since the local godoc tool no longer
ships with Go by default, so the instructions no longer work without
first installing godoc. Due to this, pretty much everyone uses the
web-based godoc these days anyways.  Anyone who has manually installed
godoc won't need instructions.

Second, it makes sure the ISC license badge is at the top with the other
badges and removes the textual reference in the overview section.

Finally, it's modifies the Installation section to Installation and
Updating and adds a '-u' to the 'go get' command since it works for both
and thus is simpler.

Package chaincfg defines chain configuration parameters for the three standard Bitcoin networks and provides the ability for callers to define their own custom Bitcoin networks.

Although this package was primarily written for btcd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use parameters for the standard Bitcoin networks or for projects needing to define their own network.

Sample Use

package main

import (
	"flag"
	"fmt"
	"log"

	"github.com/btcsuite/btcutil"
	"github.com/btcsuite/btcd/chaincfg"
)

var testnet = flag.Bool("testnet", false, "operate on the testnet Bitcoin 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.TestNet3Params
	}

	// 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)
}

Installation and Updating

$ go get -u github.com/btcsuite/btcd/chaincfg
