1. Use transaction time in streams code, similarly to how we do it in other commands.
Stop using mstime() and delete unused redis code.
2. Check for sequence overflow issue when passing huge sequence ids.
Add a test.

The old code relied on c strtod function that expected some sort of delimiter
at the end. Coincidently my unit-testing code always passed proper c strings so
strod worked as expected. EVAL passes slices to non-c string and this is why the bug was
discovered via eval call. Fixes#148.
