Summary: Response 381 is invalid except for AUTHINFO USER

Initial Comment:
Hi,

Following RFC4643, in particular see: http://tools.ietf.org/html/rfc4643#section-2.3.1

381 Password required is only valid for «AUTHINFO USER».

My understanding is that the only place where it is valid to return
NEWSNNTP_WARNING_REQUEST_AUTHORIZATION_PASSWORD is in newsnntp_authinfo_username()
[src/low_level/nntp/newsnntp.c], and that any 381 encountered elsewhere should be treated as NEWSNNTP_ERROR_UNEXPECTED_RESPONSE.

I've attached the corresponding patch.
