Right now when you want to use `subprocess.STARTUPINFO`, you need to do something like this: 

    si = subprocess.STARTUPINFO()
    si.dwFlags = subprocess.STARTF_USESTDHANDLES
    subprocess.Popen(['whatever'], startupinfo=si)

It would be much nicer to do this: 


So I suggest that the `STARTUPINFO` constructor take an optional argument that sets the flags on it.

STARTUPINFO is a class whose instances have 5 attributes.  Being able to set attributes on creation is pretty normal.  If one can optionally be set in __init__, same should be true for all.  I would recommend that params be keyword-only.

Agreed on keywords-only.
