Support authentication indicators in GSSAPI

[Dmitry Belyavskiy]

Dear colleagues,

Some time ago Alex Bokovoy proposed a patch [1] to implement support
authentication indicators in GSSAPI (RFC 6680). This patch got positive
feedback both from libssh people and from our team. It also fixes the
long-term lack of functionality [2].

May I ask upstream to consider the proposed patch?
