Make count sigops always count up to the point of parse failure.
...
We do this by allowing the parser to return the list of parsed objects
(it is an internal only api anyway) and then we use this in the sigops
counting and ignore the error. This change due to bitcoind
compatability.

...
matches how bitcoind behaves.

fix ScriptToAddress when called with 0 length script.
...
It did work by luck before, but now it works no matter what the template
tables say. Add tests for the other error cases and internal data
assertions.

Add functions to count the number of signature operations in a script.
...
To be usd for validation. Most of the codepaths teste, a few tests
missing for cases needed tests in the validation codepaths too. To be
worked on in tree.

Stop modifying the passed tx in NewScript.
...
The only time we need to zero out scripts is for calcScriptHash which operates
on a deep copy anyway. This should make the tx passed to us unmodified now.

Factor the end-of-script error handling into a function.
...
Use it to reduce code dpulication in the bip16 case.
In addition we export it so that that a user could run:
for !done && err == nil {
done, err = s.Step()
}
err = s.CheckErrorCondition()
manually instead of having to run Execute().
