efs: move headers out of include/linux/ Merge include/linux/efs_fs{_i,_dir}.h into fs/efs/efs.h. efs_vh.h remains there because this is the IRIX volume header and shouldn't really be handled by efs but by the partitioning code. efs_sb.h remains there for now because it's exported to userspace. Of course this wrong and aboot should have a copy of it's own, but I'll leave that to a separate patch to avoid any contention.
