[PATCH 2/5] sasl: Emit vnc-auth-failure signal on SASL auth failures

[Christophe Fergeau <cfergeau redhat com>]

When the SASL username or password are wrong, at the moment client
application will not get any specific notification for it, they will
just know that the remote connection was closed because of an error.

This commit adds the emission of the vnc-auth-failure signal when
vnc_connection_perform_auth_sasl() fails.
