Marcel Moolenaar 3bde119b1e Fix LINUX_TIOC{S|G}SERIAL implementation. Both do not copy data in or out 
of kernel space. Remove the ioctl supporting functions, and move the actual
code to the switch-statement. Now everybody can clearly see that the
implementation is really poor.

Also fix a typo in LINUX_TIOCGETD. The underlying function was given command
TIOCSETD instead op TIOCGETD...
