ext4fixup tool to fix wonky filesystems made by old version of make_ext4fs

The filesystems made by make_ext4fs for the Gingerbread and initial Honeycomb
releases did not round up the number of inodes/block_group to use all the
space available.  This worked, but newer kernels have additional code that
refuses to write to these filesystems.  There is a kernel patch available
to fix the problem in the kernel, but this tool was also written to fixup
the filesystems to be compliant with the new kernels.
