    Labels: channel future stream throttle  (was: channel stream throttle)

> Add configurable automatic channel output stream throttling control

> Following SSHD-754 and SSHD-768 an optional throttling mechanism has been introduced
for STDIN/STDOUT/STDERR channel streams. This mechanism is currently *optional* and requires
initial setup by the user code. We should consider reversing this and making it automatic
(unless disabled by the user). The following mechanisms should be considered:
> * {{none}} - same as current situation
> * {{default}} - {{ThrottlingPacketWriter}} (?)
> * {{window-based}} - One that examines the window size and decides according to some
(?) threshold whether to throttle or not (and how). *Note:* in this context, we would need
to be made aware when the window size changes due to {{SSH_MSG_CHANNEL_WINDOW_ADJUST}} messages
(see {{AbstractChannel#handleWindowAdjust}}).
> * {{client-based}} - Detect (?) the used client and apply throttling policy (?) accordingly
(e.g., {{TortoisePlink}})
