[35/36] Large blocksize support for ext2

From: clameter

This adds support for a block size of up to 64k on any platform.
It enables the mounting filesystems that have a larger blocksize
than the page size.

F.e. the following is possible on x86_64 and i386 that have only a 4k page
size:

mke2fs -b 16384 /dev/hdd2 <Ignore warning about too large block size>

mount /dev/hdd2 /media
ls -l /media

.... Do more things with the volume that uses a 16k page cache size on
a 4k page sized platform..

Hmmm... Actually there is nothing additional to be done after the earlier
cleanup of the macros. So just modify copyright.
