Use ext2fs_cpu_to_be32() instead of cpu_to_be32() in kernel-jbd.h

Avoid compatibility problems by using the byte swapping functions
defined by e2fsprogs, instead of the ones defined in the system header
files.  We use them everywhere else, so we should use them in
kernel-jbd.h too.

resize2fs: move bitmaps if shrinking would orphan them

It is possible to have a flex_bg filesystem with block groups
which have inode & block bitmaps at some point well past the
start of the group.

If an offline shrink puts the new size somewhere between
the start of the block group and the (old) location of
the bitmaps, they can be left beyond the end of the filesystem,
i.e. result in fs corruption.

Check each remaining block group for whether its bitmaps
are beyond the end of the new filesystem, and reallocate
them in a new location if needed.

mke2fs: calculate journal blocks just after fs initialize

We can calculate journal blocks as soon as blocksize is set.
It will help to figure out wrong journal blocks count earlier.
This will save some un-necessary initialization.

Without patch output =>
mke2fs /dev/sdc1 -J size=1048576
