ocfs2: Add a name indexed b-tree to directory inodes
This patch makes use of Ocfs2's flexible btree code to add an additional tree to directory inodes. The new tree stores an array of small, fixed-length records in each leaf block. Each record stores a hash value, and pointer to a block in the traditional (unindexed) directory tree where a dirent with the given name hash resides. Lookup exclusively uses this tree to find dirents, thus providing us with constant time name lookups. Some of the hashing code was copied from ext3. Unfortunately, it has lots of unfixed checkpatch errors. I left that as-is so that tracking changes would be easier.
