[PATCH] reiserfs endianness: clone struct reiserfs_key
struct reiserfs_key cloned; (currently) identical struct in_core_key added. Places that expect host-endian data in reiserfs_key switched to in_core_key. Basically, we get annotation of reiserfs_key users and keep the resulting tree obviously equivalent to original.
