Provide audio jack remapping

[nephele]

Haiku should provide a way to remap jacks on the motherboard as inputs and outputs. One example is my motherboarf has line in, line out and mic. I have remapped those to line out front side and center on ubuntu to connect a 5.1 sound system to it.

On linux this task can be done with hdajackretask

Somewhat like #6514 ?

To be totally honest, I have no idea what #6514 is about. If it's about software routing of audio we already do that, and something like an equilizer would be easy to add as a media node inbetween.

Anyhow, this ticket is only about configuring the physical jacks on the soundcard to behave differently.

Physical jacks, gotcha. Then for HDA hardware (do other soundcards allow to reconfigure jacks like HDA does ?) this ticket might benefit from my very early/exploratory patch over at #8476 .
