Set unallocated space when performing simple operations (#499202) 

When pasting a copied partition into an existing partition set its space
utilisation so that any unallocated space is displayed correctly before
the operation is applied.  If the destination partition is larger the
file system will be grown to fill the partition.

NOTE:
GParted will attempt to grow the the file system in this situation
regardless of whether the file system supports it or not.  These file
systems: exfat, hfs, hfs+, reiser4 and ufs can't be grown and will fail
with "growing is not available for this file system".  The preview will
also be wrong in this case for the same reason.  Everything will be
depicted correctly after the refresh.

When formatting an existing partition default its space utilisation to
unknown for display before the operation is applied.

Bug 499202 - gparted does not see the difference if partition size
             differs from filesystem size
