Looks for a file on the UDF disc/imagefile and returns the block number where it begins, or 0 if it is not found.

The filename should be an absolute pathname on the UDF filesystem, starting with '/'. For example, '/VIDEO_TS/VTS_01_1.IFO'. On success, filesize will be set to the size of the file in bytes.
