The case-insensitive implementations in f2fs and ext4 have quite a bit of duplicated code. This series simplifies the ext4 version, with the goal of extracting ext4_ci_compare into a helper library that can be used by both filesystems. It also reduces the clutter from many codeguards for CONFIG_UNICODE; as requested by Linus, they are part of the codeflow now. While there, I noticed we can leverage the utf8 functions to detect encoded names that are corrupted in the filesystem. Therefore, it also adds an ext4 error on that scenario, to mark the filesystem as corrupted. This series survived passes of xfstests -g quick.
