Every failed SG_IO request is replayed second time without data

Updates to use the new ac97

This is the newer audio used in later ALi chipsets.

This is used by some MIPS systems

This deals with several things
- Codecs that think they are modems but are not
- Abstracting modem detection out of drivers
- Abstracting digital switching out of drivers
- Codecs that have no volume control
- Codec plugins for specific setups
- Codec plugins for things like touchscreen/batmon on AC97
- More codec handlers

The plugin API is intentionally modelled on the other driver_register
type interfaces.
