Vitaly Minko to slouken

Hi all,

I wrote a patch, which allows user to rotate the screen in case of fbcon driver.
The rotation angle is controlled by SDL_VIDEO_FBCON_ROTATION environment variable and possible values are:
not set        - Not rotating, no shadow.
"NONE"    - Not rotating, but still using shadow.
"CW"         - Rotating screen clockwise.
"UD"          - Rotating screen upside down.
"CCW"      - Rotating screen counter clockwise.

The patch is based on wscons driver, written by Staffan Ulfberg.

I tested it on
Device:                Sharp Zaurus SL-C1000
SDL version:       1.2.13
Kernel version:    2.6.24.4

Best regards,
Vitaly.
