Prepare to allow to disable latency-compensation

Previously "zero custom/user latency" meant "default plugin latency".
This is now saved in a separate boolean allowing a user to reduce a
processor's latency to zero.

This also prepares for a global switch to use zero latency throughout
the whole session.
