Subject: e2fsprogs: Patches to resize2fs

The following patches fix resize2fs support for uninit_bg filesystems,
as well as a rather embarassing bug which I had introduced while
making mke2fs -j more efficient.  The final patch prohibits resizing
filesystems that have flex_bg enabled and do not have the resize_inode
feature enabled, since my testing has found a nasty bug in the flex_bg
&& !resize_inode case, and I fix isn't going to be coming right away.

In any case, this should make e2fsprogs work much better; at this
point resizing should be in good shape except for:

1)  flex_bg with on-line resizing

and

2)  flex_bg && !resize_inode with off-line resizing.

There may also be problems with flex_bg && uninit_bg; more testing is
needed there to be 100% sure there's nothing hiding in that particular
feature set combination.
