fs: API changes enabling extra parameter to return size of type loff_t
The sandbox/ext4/fat/generic fs commands do not gracefully deal with files greater than 2GB. Negative values are returned in such cases. To handle this, the fs functions have been modified to take an additional parameter of type "* loff_t" which is then populated. The return value of the fs functions are used only for error conditions.
