Recursively measures the disk usage of file.
This is essentially an analog of the 'du' command, but it also reports the number of directories and non-directory files encountered (including things like symbolic links).
By default, errors are only reported against the toplevel file itself. Errors found while recursing are silently ignored, unless G_FILE_MEASURE_REPORT_ANY_ERROR is given in flags.
The returned size, disk_usage, is in bytes and should be formatted with g_format_size() in order to get something reasonable for showing in a user interface.
progress_callback and progress_data can be given to request periodic progress updates while scanning. See the documentation for GFileMeasureProgressCallback for information about when and how the callback will be invoked.
