better latency handling in the new tunnel modules

Description
Various fixes to improve latency handling (see the patches). What's missing is:
-
No pre-emptive latency increase, like the ALSA module does with its watermark. Perhaps we need to have the same approach? Or is there some other value we can monitor? Right now it will have to glitch before it responds.
-
Once increased, the latency can never be reduced. Because every increase is after we've glitched, it's not really safe to start reducing the latency again.
