ocfs2: Add xattr lookup code xattr btrees
Add code to lookup a given extended attribute in the xattr btree. Lookup
follows this general scheme:
1. Use ocfs2_xattr_get_rec to find the xattr extent record
2. Find the xattr bucket within the extent which may contain this xattr
3. Iterate the bucket to find the xattr. In ocfs2_xattr_block_get(), we need
to recalcuate the block offset and name offset for the right position of
name/value.
