    upstream: Implement channel inactivity timeouts
    
    This adds a sshd_config ChannelTimeouts directive that allows channels that
    have not seen traffic in a configurable interval to be automatically closed.
    Different timeouts may be applied to session, X11, agent and TCP forwarding
    channels.
    
    Note: this only affects channels over an opened SSH connection and not
    the connection itself. Most clients close the connection when their channels
    go away, with a notable exception being ssh(1) in multiplexing mode.

Date:   Fri Jan 6 02:42:34 2023 +0000

    upstream: Add channel_set_xtype()
    
    This sets an "extended" channel type after channel creation (e.g.
    "session:subsystem:sftp") that will be used for setting channel inactivity
    timeouts.

    upstream: tweak channel ctype names
    
    These are now used by sshd_config:ChannelTimeouts to specify timeouts by
    channel type, so force them all to use a similar format without whitespace.

    upstream: Add channel_force_close()
    
    This will forcibly close an open channel by simulating read/write errors,
    draining the IO buffers and calling the detach function.
    
    Previously the detach function was only ever called during channel garbage
    collection, but there was no way to signal the user of a channel (e.g.
    session.c) that its channel was being closed deliberately (vs. by the
    usual state-machine logic). So this adds an extra "force" argument to the
    channel cleanup callback to indicate this condition.
