Allow individual ports to use alternate pin settings (swap dsr & cd)
via the new DIGIIO_SETALTPIN ioctl, and allow the port's ALTPIN setting
to be queried via DIGIIO_GETALTPIN.

The initial state and lock devices are normally used to set and/or
lock ALTPIN settings although the device itself may also be used.

ALTPIN settings are applied per-device and apply to both the callin
and callout device at the same time.
