* test case added to avoid adding them later

realpath() may return false in case the directory does not exist since we can not be sure how different PHP versions may behave here we do an additional check whether realpath returned false

php can only parse filesize units up to gigabytes, not terabytes or petabytes.

Instead of leave two decimal places which is confusing, round the byte
values correctly to the closest byte.

instead of used space when used space exceeds the quota (soft quota).

init_var and init_radio  where only used in the installation template

Added argument to getFileInfo() to disable adding the size of
mountpoints to a directory's size.
