Build and packaging library

Jan Lindemann a739eb0763 lib.Result: Initialize with status = None ... Define default parameter values for Result's constructor, namely None for exit status, stdout and stderr. Instantiating a Result object without parameters signifies "this object doesn't contain data from a real process's exit event". Up to now, similar meaning has been hand-crafted by ExecContext's run() and friends by using an error exit status (1) to make sure it wasn't mistaken for success. This commit formalizes that into the Result structure itself, but uses None instead for the exit status. Controlling default values in Result itself also means that the Result class gets better awareness of what it contains, and its log messages and stdin / stdout can be more fitting: - If a real process failed, make stdout return at least b'' - If a real process succeeded, make stdout return at least b'' Returning something from .stdout on success fixes a real bug: An attempt to access what "rpm -U somepackage.rpm" returns, namely nothing, raises a bogus exception, because stdout is None.
