Bug 195310 – Web Inspector: Protocol: add type checking when commands are called via invoke

[Devin Rousso]

Right now we only do type checking for when it is called like a normal function.

Good change but.. it needs to be tested. Please update inspector-backend-invocation-return-value.html to exercise the invoke() code paths.

Could we just require the first argument is always an object to simplify this a bit:

    if (typeof commandArguments !== "object")
        return deliverFailure(`invoke expects an object for command arguments but it was a '${typeof commandArguments}'.`);

    let parameters = {};
    for (let {name, type, optional} of instance.callSignature) {
        if ((!name in commandArguments && !optional)
            return deliverFailure(`Missing argument '${name}' for command '${instance.qualifiedName}'.`);
        ...
    }

In other words I don't think we should allow calling invoke with no object (even if there are no required arguments).

I'm fine with that.  I wasn't sure which approach we wanted to take, so I just matched the existing functionality.
