[polari/wip/fmuellner/add-channel-error-prop] room: Add :channel-error property

[Florian Müllner <fmuellner src gnome org>]

commit 57a55d995ef998dd4a833e0a27afda70bcfc6507
Author: Florian Müllner <fmuellner gnome org>
Date:   Wed Feb 13 18:43:26 2019 +0100

    room: Add :channel-error property
    
    While we have TpAccount:connection-error to indicate problems with
    a network connection as a whole, we don't have any indication for
    errors that happen during channel creation (for example a full or
    invite-only room).
    
    Add a new :channel-error property that can be used to pass around
    such an error condition.
