Subject:	B20 patch: ioctl modes for fhandler_console

Hi!

The class fhandler_console implements `tcgetattr()' and
`tcsetattr()' with modes TCSANOW, TCSADRAIN and TCSAFLUSH.

The corresponding ioctl calls TCGETA, TCSETA, TCSETAW and
TCSETAF are missing. Older sources use them instead of the
above functions.

The following patch adds the ioctl calls by calling the
corresponding tc[gs]etattr function.

Regards,
Corinna
