gpio-test updated for interrupt tests
- Reorganize gpio initialisation
- no longer need to use gpio output
- push global structure onto the heap memory
- use tasklet and trigger it from interrupt service routine
- add test-gpio target to Makefile

spi_parport and gpio_parport first release
spi_parport:
- fully rework of the spi_parport
- first real test done
gpio_parport:
- add compile feature 'use parport exclusive'
- add compile feature 'claim parport' as a hack to share one parport
by both drivers gpio_parport and spi_parport.
- correct GPIO signals, which are inverted used
- add module parameter for force setting interrupt line
- add module parameter for force setting GPIO base address

Add gpio_parport and gpio_test
Correct some compile errors in spi_parport.
Note: spi_parport just compiles and is not yet tested functional.
Getting more familiar with GPIO handling using the GPIO lib
of kernel with the GPIO controller driver and gpio_test driver.
Both drivers gpio_parport and spi_parport should work later
close together or should share the same parport device.

spi_parport
Start using list struct instead of ugly global struct.
Add missing SPI mode functions.
Note: The driver is just compiled and not tested!

Rename spi_tty into spi_parport
Just rename spi_tty.c into spi_parport.c need for
git to keep track version history.
Update the Makefile accordingly.

Test modalias with spi_tty
Also add some comments and marks things, which currently unclear.
Spi_tty is just a test driver to become more comfortable with the
SPI master controller and the parport.

SPI Parport controller forked from spi_butterfly
It is just the first try to get a feeling, how the SPI
Parport controller can work on the parport.
