genext2fs: support large files and filesystems without using large amounts of memor

Hi RP, Saul, Paul, Darren, Mark, Josh and joaohf and all, please comment.

Let's figure out if this big patch is accepatable or not...

With this patch, I can successfully create a 8.5GB .ext3 file with genext2fs. The speed is slow -- I spent about 1.5 hours.

The following changes since commit 265903bdffb10c95ceaf7a892151a50b67939c71:

procps: don't print error message with kernel 3.0+ (2012-03-28 10:16:30 +0100)
