This is a revised set of the on-line resizing patches after my
cleanups. I've folded some patches together, as well as collapsed a few
functions to make the code easier to understatnd/maintain.
I've also fixed up the English in a few places in the commit
descriptions and in the comments, as well as made some style fix ups.
Finally, I've added some error checking to make sure the on-line
resizing code doesn't try to resize file systems that it can't handle
(most notably, meta_bg file systems). We do need to add meta_bg support
into the on-line resize, but this patch series has enough benefits that
we should get this merged first, and then we can add the meta_bg support
later.
