== TTY Layer ==
1. Rework our current TTY layer into a module
1. Create an API that fulfills the need of a serial port
* traditional RS232
* serial over USB.
1. Integrate the new API into the serial drivers that are already in our
repository,
1. Make sure everything works as expected.
1. Until now the serial port was reserved for kernel debugging, but it is
now time for proper userland support.

Comment (by mmlr):
I've implemented a generic tty module based on the tty driver in r39760
and ported over usb_serial to it in r39762. The pc_serial (RS232) driver
still needs to be ported and the tty driver should now be reworked to use
the tty module and only provide the driver specific code that was left out
in the generic module. I'm going to work on the tty driver but will leave
the pc_serial driver alone. François still wanted to keep backwards
compatibility for now and I myself don't have any real serial ports where
I could test it on anymore.
