Subject: [PATCH 1/2 e2fsprogs] support for large EAs

Hi,

This patch adds large EA support for e2fsprogs.

- add EXT4_FEATURE_INCOMPAT_EA_INODE feature
- inode_ea_map bitmap is added for tracking non-orphan EA inodes. Orphan EA inodes get linked to lost+found.
- xattr handling is needed for deleting corrupt EA entries

Ted, this patch is actually based on top of the e2fsprogs-expand-extra-isize.patch I had sent about a month back. If you are satisfied with the approach, I can send a patch series which applies to the tip of the e2fsprogs tree.
