[glib-networking/mcatanzaro/tls-exporter: 1/2] Finalize implementation of G_TLS_CHANNEL_BINDING_TLS_EXPORTER

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 286df976d538970a30a1d9c0ffedebe40bdeab19
Author: Michael Catanzaro <mcatanzaro redhat com>

    Finalize implementation of G_TLS_CHANNEL_BINDING_TLS_EXPORTER
    
    Instead of hiding it behind a secret dummy value, let's implement the
    real deal.
    
    Depends on: glib!2853
    
    Fixes #191
