Handle a new type of data block that has a 32-bit offset. These are identical to the normal blocks except that the offset is now in the 32-bit field that was previously 'sr'. A new file version of 3 indicates that it is mandatory to process the long-offset blocks, so that older code without that support will reject the file. The original 'sr' field was never used by the driver so it has been renamed offset32.
