[PATCH 5/6] gatchat: support for auth NONE

[Giacinto Cifelli <gciofono@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1650 bytes --]

Added authentication method G_AT_PPP_AUTH_METHOD_NONE and its handling.

This method is already used in the code, and
the patch is just allowing its explicit use, on top of the implicit
selection done when username is empty.
