Svarog a2b69a84f4 [NOD-48] Make wire.NewMsgTx recieve all paramaters that go into MsgTx, and compute what can be computed. (#216 )

* [NOD-48] Update wire.NewMsgTx to recieve all fields in msgTx

* [NOD-48] Fix all compilation errors resulting from modification of wire.NewMsgTx

* [NOD-48] Calculate payloadHash iff subnetworkID is not native

* [NOD-48] Update all places the instantiate wire.MsgTx to use wire.NewMsgTx

* [NOD-48] Remove 'wire.' calls inside wire package

* [NOD-48] Made newMsgTx with all parameters private, and added a few public functions that take various arguments for all common use-cases

* [NOD-48] Explicitly pass SubnetworkIDNative instead of nil to newMsgTx

* [NOD-48] Remove option to pass nil to newMsgTx

txscript

Package txscript implements the bitcoin transaction script language. There is a comprehensive test suite.

This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate bitcoin transaction scripts.

Bitcoin Scripts

Bitcoin provides a stack-based, FORTH-like language for the scripts in the bitcoin transactions. This language is not turing complete although it is still fairly powerful. A description of the language can be found at https://en.bitcoin.it/wiki/Script

Installation and Updating

$ go get -u github.com/daglabs/btcd/txscript

Examples

Standard Pay-to-pubkey-hash Script
Demonstrates creating a script which pays to a bitcoin address. It also prints the created script hex and uses the DisasmString function to display the disassembled script.
Extracting Details from Standard Scripts
Demonstrates extracting information from a standard public key script.
Manually Signing a Transaction Output
Demonstrates manually creating and signing a redeem transaction.

GPG Verification Key

All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from the btcsuite developers. To verify the signature perform the following:

Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
Import the public key into your GPG keyring:
```
gpg --import GIT-GPG-KEY-conformal.txt
```
Verify the release tag with the following command where TAG_NAME is a placeholder for the specific tag:
```
git tag -v TAG_NAME
```
