Don't waste CPU time on the master or headphone output if no device is enabled for master or headphone.

[RJ Skerry-Ryan]

If no master or headphone device is selected, we should just not calculate the master or headphone output.

(Depends on being able to detect when the sidechain is active).

[RJ Skerry-Ryan (rryan)]

We should also provide COs that represent when a master or headphone output is active so we could hide or disable the relevant parts of the mixer section.

I will try to fix this along with Bug #1203249.

It is hard to find out from the hardware preferences if master and/or headphone is required, because recording feature and headphone mix.
I will add dedicated preference option, to disable master mix.

I guess I would prefer to revert this unless there's a compelling usecase or performance implication. It's confusing and there are lots of situations where a master mix is required even if there's no master output
