Windows: better -legacy-stdio-prompts fidelity.

Browse Source 
In 0.81, some prompts (such as host-key prompts) went to stderr, while
others (such as username and password prompts) went to stdout.
With -legacy-stdio-prompts (or if we otherwise couldn't get console
handles), we were sending all such prompts to stdout, which might have
messed up someone's workflow if they were interacting with the
non-username/password prompts programmatically.
