Port a series ext2 balloc patches from Hugh to ext3/4. The first 6
patches are against ext3, and the rest are aginst ext4.
------------------------------------------------------
Subject: ext2 balloc: reset windowsz when full
From: Hugh Dickins <[EMAIL PROTECTED]>
ext2_new_blocks should reset the reservation window size to 0 when squeezing
the last blocks out of an almost full filesystem, so the retry doesn't skip
any groups with less than half that free, reporting ENOSPC too soon.

Sync up reservation fix from ext2
