Bluecherry solo6x10 driver

The mpg4 data coming from the driver sometimes contains corrupted mpg4 frames that are not conform to mpg4 standard. In order to avoid those frames the attached patch detects and eliminates most of these bad frames in the driver. The patch also fixes some errors in Mpg4 VOL headers and fixes the PAL-M issue.

The bad frames are mostly detected by size inconsistencies. This raises the impression that the errors are caused by timing issues in the communication between driver and hardware. The patch does not fix these issues, it just eliminates the corrupted frames.
