Make a list out of an argument.
Values from `distutils` argument parsing are always single strings;
values from `optparse` parsing may be lists of strings that may need
to be further split.
No matter the input, this function returns a flat list of whitespace-trimmed
strings, with `None` values filtered out.
>>> listify_value("foo bar")
['foo', 'bar']
>>> listify_value(["foo bar"])
['foo', 'bar']
>>> listify_value([["foo"], "bar"])
['foo', 'bar']
>>> listify_value([["foo"], ["bar", None, "foo"]])
['foo', 'bar', 'foo']
>>> listify_value("foo, bar, quux", ",")
['foo', 'bar', 'quux']
:param arg: A string or a list of strings
:param split: The argument to pass to `str.split()`.
